ASHLEY GREEN, Grove Farm House (SP 986 042)


Felling dates: Winter 1499/1500 and Spring 1499


Rafters 1499 (32C); 1481 (22); 1498 (21¼C); 1498 (29); Purlin 1493 (27); Lintel (0/1). Site Master 1368-1499 GROVEFM (t=8.6 MASTERAL; 8.4 HANTS97; 7.7 SOUTH)


Grove Farm is the only building standing within a medieval moat. Of three bays and built of brick and stone, the walls may possibly predate the roof which has here been dated to 1499/1500. One sample from a ground-floor window lintel proved undateable, so dendrochronology cannot resolve the question of phasing. The roof is of interest, with the centre trusses each containing a cranked tiebeam and raking struts under the junction of the single butt purlins. The principal rafters are suddenly diminished substantially near the apex, and the purlins are jowled about one foot from the ends in both planes. None of the timbers are decorated, except the V-struts which are chamfered with stepped run-out stops. The rafters in the centre bay have evidence in the form of diagonally aligned peg-holes for a large dormer or lower cross-gable, now lost. Another interesting feature is a pointed wooden arched doorhead leading from the end bay onto the present stairs, possibly relating to a removed stair tower or gardrobe. Dating commissioned by Mr A S Harman as part of an ongoing study of the site.

Roof joists/purlins 1612 (38C, 16¼C); 1613 (25C, 32C 19½C); 1614 (31C). Site Master 1450-1614 BOARSTL2 (t=9.7 MASTERAL; 8.6 CHAWTON1; 8.4 EASTMID)


The tower and the moat at Boarstall are all that remains of a moated manor house complex dating from the early 14th century. In 1998 the National Trust carried out repairs to the roof of the building and alterations to the adjoining annexe and as part of this work commissioned Oxford Archaeological Unit to maintain an archaeological watching brief. The Trust also commissioned dendrochronology, hoping to establish the construction date of the present roof structure and possibly the original tower.

Cores taken from ceiling joists at ground floor level gave a felling date of winter 1312/13. This ties in precisely with a licence to crenellate the manor at Boarstall awarded in 1312. Cores taken from the roof joists gave a felling date of 1614/15. It would appear that the top storey of the building was substantially rebuilt at this date when the height of the parapet was raised. Archaeological evidence from the watching brief has confirmed that the existing crenellated parapet was built directly over the 14th century parapet, thereby encasing the embrasures of the original crenellations. The tower and the manor house are depicted in superb detail on an engraving dating from 1695 and it seems likely that the tower was raised in height to provide a viewing point over the formal garden landscape surrounding the manor house.

BRILL, Brill Post Mill (SP 652 141)


(a) Meal beam Felling dates: Winter 1685/6


(b) Phase two Felling date range: (OxCal modelled) 1719-33 (unrefined 1713-45)


(c) Phase three Felling dates: Winter 1759/60


All timbers (8/13). (a) Meal beam 1685(23C); (b) Crown tree 1706(9); Side girts 1707(h/s), 1708(h/s); (c) Frame member 1735(h/s); Main post 1746(7); Shear 1753(3); Windshaft 1759(25C). Site Master 1585-1759 BRILL1 (t = 10.5 HANTS02; 9.8 OXON93; 9.7 CRMASQ01)


As in many windmills several phases are evident in the existing structure. The meal beam was the only dated component of what appears to be the earliest extant phase of the buck, though a timber with ‘-68-’ carved on it has been interpreted as coming from the 1680s. Other components of the buck (b) represent a phase in the early eighteenth-century. In previous windmill studies the main post has been found to be the oldest surviving timber, but here it is part of the third phase, corresponding to the rebuilding indicated by documentary evidence that the mill was blown down in 1757. None of the trestle timbers could be dated. Dating commissioned by the Bonwick Milling Heritage Consultancy.

BUCKINGHAM, 12-16 Stratford Street Cottages (SP 700 343) Re-used timber


Felling date range: 1516-29


Re-used post 1516(28); Longitudinal beams (0/3), Corner post (0/1); Purlin (0/1). Site Master 1409-1516 srcb5 (t = 6.6 WILNGTN1; 5.6 EASTMID; 5.5 OXON)


The row of cottages was originally formed by the building of a three bay timber framed building (Nos. 12-15) with a small extension to the north-east end (No. 16). The rear wall still survives as a somewhat crude box-framed construction with wattle and daub infill. The three trusses have queen struts with wattle and daub infill. The only datable timber is a post which appears to have been part of a arch-braced roof, and does not represent the date of the present structures. Dating commissioned by Oxford Archaeology on behalf of the owners.

BUCKINGHAM, West Street, Castle House, (SP 694 340),


Rear west range Felling dates: Winter 1405/6; Winter 1406/7 Queen post 1373(+12NM);


Principal collars 1383(h/s), 1391(6); Windbrace 1406(16C); Tiebeams 1385(h/s), 1405(32C). Site Master 1272-1406 CASTLEHO (t = 10.1 ANGLIA03; 8.0 OXON93; 7.1 HANTS02) .


This large town house is Grade I listed. It consists of a main range built in 1708 with what are thought to be late-fifteenth-century wings to the rear on either side. The rear wings are known to have been altered around 1623, and the left (west) wing was altered in 1881. The roof of the rear west range contains three trusses from what was once an open hall. The two main trusses have double hollow-chamfered arch-braced and cambered tiebeams with queen posts to a principal cambered collar and to a secondary collar. Posts frame the arch bracing to the collars and are multi-foiled to the upper collars, meeting in an ogee arch. The lower end truss has an arch-braced-collar truss with foiled bracing to secondary collar. There are two tiers of clasped, windbraced purlins. The principal collars have been cut to give access to an attic room.

Chenies Manor, noted for its Tudor decorated brick chimney stacks, consists of a west and a south range. The west range is composed of two blocks at right angles to each other. A tower housing a spacious spiral staircase with moulded brick handrail in the south-east angle between the blocks gives access to both. Only the south block retained complete sapwood which provided precise felling dates ranging from spring 1537 to summer 1538. The felling date ranges for the northern block are consistent with the dates from the south block, demonstrating that the two are broadly contemporary. Their roof structures are very similar, the integral ceilings constructed of axial binders tenoned into the tiebeams carrying framed ceiling joists indicating that they were ceiled from the outset. No evidence could be found for the smoke-blackened timbers mentioned in a Country Life article of 1982.

The spiral staircase leads to an upper gallery, a small range connecting the west to the south range which houses the long gallery, known locally as the Armoury. Ten timbers were sampled in the long gallery, and three from the ceiling of the long room on the ground floor, demonstrating that the range is of one build. The felling dates suggest that the south range was constructed during 1552 or shortly after. The north block of the west range and the roof timbers in the long gallery have remains of red ochre-painted assembly marks, an unusual feature. The construction of the south range is of interest in that both major floor frames are composed of transverse beams with tall thin joists (only common after 1600). The earliest previously-known example of similar floor construction was from c.1562 (datestone) at 6-7 Canonbury Place, Islington, although the Wolsey kitchen at Hampton Court has similar undated ceiling joists which are thought to be original (Richard Bond, pers. comm.).

CHILTON, Easington Farmhouse (SU 687 103) 


(a) Ex situ mid-rail Felling date range: 1490-1522


(b) Roof and cellar Felling dates: Summer 1726 to Spring 1727


(a) Mid-rail 1481(H/S); (b) All timbers (5/7) Principal rafters 1725(13), 1726(14C); Common rafters 1726(24¼C), 1726(7C); Cellar beam 1725(18½C). Site Masters (a) 1383-1481 esf01 (t = 5.8 BRUTON3; 5.6 KGWBSQ01; 5.3 CHKSPQ01); (b) 1640-1726 EASNGTN (t = 8.5 WIGALL46; 7.8 CLAYDON; 7.5 OXON93).


A map of 1687 shows a house of roughly similar proportions on the site, and the single timber removed from the wall suggests a date for this structure. The present building however appears to have been largely rebuilt in 1727 or thereabouts. The house has a long roof of oak rafter couples and principal rafters above the ties, with chiselled assembly marks. Dating commissioned by the owner.

HIGH WYCOMBE, Bradenham Manor (SU 825 970) 


Felling dates: Winter 1652/3 and Spring 1653


Principal rafters (4/8) 1652 (19C, 19¼C 22C, 25C); Purlins (2/7) 1652 (22¼C); 1643 (9); Hip rafters (1/2) 1646 (8). Site Master 1553-1652 BRADNM1 (t=8.8 MASTERAL; 7.2 OXON93; 7.1 WALES97)


During 1997, an archaeological watching brief was maintained at Bradenham Manor by the National Trust during work on the roof and dendro cores were taken from the principal members of the trusses. The house is not well documented but the earliest part - the south end of the building - was believed to date from c.1642 after the acquisition of the estate by Sir Edmund Pye. It was then substantially enlarged, possibly in the 1670s after the estate passed to Sir Edmund’s daughter, Marjery. The roof over the south section now has a single east-west ridge. However, the survival of a single redundant truss beneath the west range roof suggests that it was originally double ridged, the more northerly ridge having been removed and replaced by two major north-south ridges when the building was enlarged. However, felling dates of 1652/53 were obtained from both the east-west ridge and one of the north-south ridges. It is concluded that the east-west ridge is indeed the earliest i.e. 1652/53 and the later north-south ridges re-used some of the timbers from the 1652/53 roof. It also appears that the south section of the building dates from c.1652. Dating commissioned by Gary Marshall of the National Trust as part of the archaeological recording.

An interesting feature of the mill is the fine turning on the main post, both at the junction of the cross trees and where it protrudes into the meal floor. 1627 is carved on a side girt, and this has led to the claim that it is the oldest extant post mill in Britain. The dendro dating suggests that it is even earlier. Changes to the brickwork piers which support the cross trees indicate that the mill has been raised once, and possibly twice, the most recent being in the mid 1820s. Dating commissioned by the Pitstone Mill Committee.

LITTLE MISSENDEN, The Manor House (SU 922989)

(b) South wing Felling dates: Spring 1624


(a) Queen strut 1544(25¼C); Rafters (4/5) 1516, 1517, 1545(16¼C, 19½C); (b) Collar 1596(H/S); Principal rafters 1623(14¼, 15¼C); Purlin(0/1). Site Masters (a) 1425-1545 LMSSNDN1 (t = 6.4 CHENIES1; 5.7 NOSTELL1; 5.5 SENGLAND); (b) 1533-1623 LMSSDND2 (t = 6.5 MARLBORO; 6.2 SDSASQ02; 5.3 COTTESMR).


This complex building has two principal ranges, both apparently truncated and both heavily modified in the eighteenth and nineteenth centuries. The 1546 timber-framed wing (a) is set back behind the more dominant roadside range of 1624 (b). The latter is brick-built, of three-storeys, L-shaped on plan. The main roof has three trusses, the rafters being tenoned into the purlins and with the eastern end roofed at right angles like a cross-wing. The windows, where they have not been blocked, are mostly 12-pane sashes, replacing timber cross-windows. On the north side the stair turret has brick ovolo-mullioned cross-windows, with the bricks plastered to resemble stone. There are three main rooms, a service room at the east end, a kitchen in the centre and a parlour at the west end.. The fireplace to the kitchen has a chamfered wooden lintel with down-turned ends and is covered with many apotropaic marks and the initials TH. Above the fireplace are four arched recesses of unknown purpose.

A wide central entrance hall forms the base of this L-shaped range linking the roadside and earlier range. It is entered by a semi-octagonal porch added in the C18th. Behind this, in the angle, is the stair wing also of 1624 and containing a very fine open-well stair, which rises through two storeys to the top floor. It has turned balusters joined by semi-circular arches and square newel posts topped by huge pointed finials There is also a half balustrade against the wall, a feature only found in a few of the more important houses of the period (e.g. Blickling Hall, Norfolk and Hatfield House, Herts.) The lower flight of the stair has clearly been turned through 90 degrees to give a long straight flight down to the present entrance hall. The original arrangement would have been much better suited to a main entrance facing the adjacent church, with the stair being approached by the long passage, now somewhat redundant, flanking the kitchen and parlour and leading to what are now French windows in the west wall. Such an arrangement also implies a lost range to the north of this passage, forming a more imposing frontage onto the churchyard. Exposed timbers in the north passage wall tend to support this hypothesis.

The ‘base’ of the L-shaped range is linked to the earlier timber-framed range of 1546, aligned east-west and extending eastwards beyond the semi-octagonal porch. Originally two storeys and of four bays, the outer bays have been converted to hipped ends. The roof has clasped purlins and curved windbraces. The central truss was originally closed, and had two queen struts. Of the wall-framing, only some close studding and some braces survives on the south side. The north wall appears to have had close-studding but at the east end of the wall-plate there are pegs and mortises only for two widely spaced studs. Some late C16th wall painting survives on the brace and the studs at the east end of the south wall. A stack was later inserted adjacent to the central truss, on the northern side, perhaps after the 1624 range was added at the expense of a former lateral stack on the south wall. The inserted stack was itself later removed, probably when the first floor was taken out in 1771 and the range converted into an apsidal-ended panelled room to house the paintings of the then owner, Dr Bates. The tiebeam/wall plate at the west end has no pegs for braces, which would imply it was an inside wall. The wing, now truncated by a C19th single-storey dining room range at right angles to it, may thus have originally extended westwards ‘hitting’ what may have been the proposed eastward extension of the roadside range. Thus the 1624 alterations by the Style family would have essentially created a courtyard-style plan but with the magnificent stair filling the central well. The dating was commissioned by the owner.

LONG CRENDON, The Courthouse (SP 698 091)


Felling date range: 1483-7


Joists (1/5) 1480 (14+5±2C) Site Master 1422-1480 lcch3 (t=5.0 HANTS97; 4.8 OVERTON2; 4.7 GROVEFM)


The Court House, Long Crendon, is a long five-bayed building jettied on the west end and the front, with the exception of the east bay where it is treated as a Wealden to allow it to function as an open kitchen. Each bay was separated on the ground floor to form individual rooms, but with the exception of the upper part of the kitchen and stairs, the first floor was originally one long open room, as it still remains today. The roof consists of alternating tiebeam and arch-braced collar trusses, all of slight scantling timbers. Virtually all of the timber within the building was unsuitable for dendrochronology; only five samples from the first floor joists had sufficient numbers of rings to be worth sampling, and only one with incomplete sapwood dated. The building was probably originally built as a church house, being adjacent to St Mary’s Church, with the top floor being used as a courtroom. Dating commissioned by Jeremy Bowden of the National Trust, as part of an ongoing programme of re-presentation of their properties.

LUDGERSHALL, The Hovel (SP 663 176) 


Felling dates: Spring 1812


Lodged ceiling beams (3/4) 1802 (32); 1811 (40¼C, 42¼C); Post (1783 (14). Site Master 1671-1811 THEHOVEL (t=12.5 ORIEL1; 11.6 MASTERAL; 10.3 HANTS97)


The Hovel is an extraordinary survival of a squatter’s cottage built on a low-lying site adjacent to a small brook. The small two-roomed cottage complete with central brick chimney stack and lobby entry is constructed of earth-fast posts with forked ends in which the wall plates are nestled. The walls are wattle-and-daub with some wychert, and the roof consists only of small twisted branches lodged on the wall plates supporting a solid thatch roof of twigs and brushwood. Given that virtually all of the wood used in the building is untrimmed roundwood of small scantling, it is remarkable that a 140-year chronology could be constructed producing exceptional matches with regional reference chronologies. Whilst the primitive construction of the cottage employing virtually no carpentry techniques might lend support to the tradition of squatters cottages being erected overnight on waste ground, an inscribed date of 1811 on a fireplace brick suggests that the sequence of construction here might be slightly more complicated. Renate John commissioned the dating on behalf of the owner.

Door post 1794(h/s). Site Master 1719-94 kya10 (t = 8.7 HANTS97; 8.2 MASTERAL; 6.6 THEHOVEL)


The Kya was a small unlisted cottage in Ludgershall, Buckinghamshire which was recorded as a condition of planning approval prior to its demolition. The cottage was two bays wide and essentially single storey with a small inserted loft in one half. The walls were of cob (a constructional technique of some importance in Buckinghamshire), although the front wall had been rebuilt and stepped back; the roof was thatched. The roof contained a single central truss incorporating collar and raking struts with simple birds-mouth ends rather than mortice and tenon joints; the rafters used riven and cleaved timber. Seven oak rafters and two oak purlins all came from trees felled in the spring or early summer of 1569. The only other timber dated was a door post at the rear of the cottage. The rafters and purlins appear primary to the building, providing a good date for the construction of The Kya, while the door post probably indicates the construction date of a rear extension.

During 2000 English Heritage were commissioned to produce a survey of the buildings at Lodge Farm. Clustered around a large courtyard, this intriguing group of buildings owned by the National Trust occupies a commanding hill-top location overlooking the Thames Valley. The tall flint and brick house dates from the early 17th C and was probably built as a hunting lodge by the Borlases, owners of Bockmer House, 1.5 km north of the lodge. In the late seventeenth century it was downgraded to a farmhouse. Dormer windows were added to the roof to provide attic accommodation and a single storey outshut was added on the east side of the building to provide a kitchen. Despite its reduced status the building remained as a prominent eye-catcher, embellished by the addition of the dormers, which were executed in a style matching the original construction. Unfortunately the timbers from the house were all too fast-grown to be worth sampling for dendrochronology.

The farm buildings however were more promising. A stable range on the north side of the farmyard produced a felling date of 1561/2, with evidence for repairs between 1723 and 1726, and an extension eastwards in 1784/5. At about the same time as the stables were repaired, a three-bayed timber-framed barn on the east side of the farm yard was built, again using primarily re-used timbers. On the west side a large clunch barn of five bays with central porch was constructed of mainly re-used timbers, but the four tiebeams appeared primary and produced a felling date of 1564/5. These dates suggest that the lodge was added to an existing manorial farm.

Baylins Farm comprises a two-bay hall with a five-bay integral cross wing. The central truss to the hall had moulded posts and arch braces to the collar, and there were two sets of clasped purlins. The cross wing is exceptionally long, but appears to be of one phase. It contains five queen-strut and one king-strut trusses with short spandrel braces to the tiebeams, and has a single set of clasped purlins with wind braces. In 1562/3 the hall was floored over with both the joists and main beam of the ceiling being ovolo-moulded. Dating commissioned by Dr James Moir on behalf of the owner, Mr Oliver Heal.

Foundation beams 1613(4), 1614(9); Lower plate 1596; Braces 1612(2), 1625(14¼C). Site Master 1472–1625 OLNEY (t = 12.5 ANGLIA03, 11.1 OXON93, 10.5 WHITOWR7).


This is a large, approximately square, frame with eight bell pits, more or less fi lling the cross-section of the tower. Very large foundation beams, approximately 16 inches square, support the frame which is also constructed from very large timbers. Several of the timbers have been renewed or replaced over the years, although a good number of original elements remain in place. Dating commissioned by Olney PCC.

All timbers (16/20). (a) Wall plates 1684(1), 1716(24¼C); Principal rafters 1703(5), 1709(16), 1716(18½C); Purlins 1712(21), 1716(27¼C); (b) Tiebeam 1680(2); Mid-rail 1687(h/s); Brace 1698(h/s); Wall plate 1708(10); Posts 1710(12), 1710(23); (c) Principal rafter 1713(9); Purlin 1717(32¼C). Site Master 1586-1717 STOWE9 (t = 8.5 BLSBSQ01; 7.5 STOWE6; 7.4 OXON93)


The main building is listed as having been built in 1717-19 for Viscount Cobham. The buildings to the rear of the main range were of less certain age. On the west side, a timber-framed building now in a poor state of repair was thought possibly to have a much earlier origin as a precursor to the current main building, although it is here shown to be at most only a few years earlier. This study shows that a range of buildings to the east at the rear was built as part of the same campaign as the main range. Dating commissioned by the National Trust.

STOWE, Stowe Landscape Gardens (SP 680 363), Corinthian arch


Felling dates: Spring 1765; Summer 1765; Spring 1766; and Summer 1766


Rafters 1764(19¼C, 20¼C, 21¼C, 23½C, 24¼C), 1765(24½C); Arch ribs 1764(23¼C), 1765(23¼C); Cornice packers 1765(26¼C, 30¼C); Purlin (0/1). Site Master 1653-1765 STOWE8 (t = 9.5 STOWE2; 8.2 STOWE7; 8.1 READING),


As part of its restoration of the garden and park buildings at Stowe, the National Trust has maintained an archaeological watching brief over all repairs and alterations, and carried out building recording and dendrochronology to provide evidence to assist the restoration. The latest building to be sampled is the Corinthian arch which closes the south vista from the house. Once planted, it also terminated the north end of the Buckingham Avenue. The arch contains two houses, originally for gatekeepers. Documents record that the arch was designed in 1765 for Earl Temple by his young cousin, Thomas Pitt, later Lord Camelford. Building accounts suggest that it was completed in 1767, confirmed by the dating.

STOWE, Stowe Landscape Gardens (SP 6695 3885), Haymanger Pond sluice


Felling date ranges: 1766-1798, 1780-1812


Ex situ board 1766 (9); Wedges 1770 (H/S), 1771 (H/S); Stakes (0/2); Beams (0/2). Site Master 1682-1771 STOWE3 (t=5.3 STOWE2; 5.0 STOWE1; 3.4 READING1)


In 1996 the Heritage Lottery Fund provided a grant to the National Trust to purchase the parkland surrounding Stowe Gardens in Buckinghamshire. An additional grant in 1998 has enabled a programme for the restoration of the former parkland features and buildings which is still in progress.

The Haymanger Pond was one of a chain of holding lakes for the estate sawmill. However, the dam was breached and the water drained during the 1940s. The area of water depicted on 19th century maps is believed to have incorporated a series of stew ponds recorded on an estate survey of 1630. However, it is unclear whether elements of these earlier features are incorporated within the dam undergoing restoration.

n order to provide information for the restoration of this feature an archaeological evaluation trench was cut through the breach. This examined a partially exposed timber framework, which was sampled for dendrochronological dating. The felling dates for the timbers sampled range from 1766-1798 and 1780-1812, and there are at least three phases of sluice construction after this. Unfortunately, not enough evidence survives for a comprehensive reconstruction of the former operation of the sluice. See following entry from 2004 for updated analysis and interpretation.

Home Farm is a National Trust property acquired in 1995. Until 1921 it had served as the principal farm for the Stowe Estate, providing meat and diary produce to the main house. The farm consists of four brick ranges arranged around a courtyard, accommodating such functions as animal housing, crop storage, etc. The brickwork is ingeniously laid as sloping courses following the lie of the land, though with vertical jambs to doorway and window openings. A building survey by Gary Marshall (‘Stowe Home Farm Vernacular Buildings Survey, 1997’) suggested a late eighteenth-century date for the farm, based on an account reference for digging foundations for a farm in 1791 and supplying 1,600 ‘Countess Slates’ in 1807.

The Haymanger Pond was one of a chain of holding lakes for the estate sawmill. The dam was breached and the water drained during the 1940s. The area of water depicted on nineteenth-century maps is believed to have incorporated a series of stew ponds recorded on a survey of 1633. However, it is unclear whether elements of these earlier features are incorporated within the dam. Structural evidence suggests that there were at least three phases after the construction of the dam sluice. Initial results were summarised in 2001 (D. H. Miles and M. J. Worthington, VA 32 (2001), 76). Further excavation of the dam by Oxford Archaeology during 2002 allowed further sampling, and the results are summarised here, superseding the 2001 VA entry.

During the summer of 2002, the mill pond at Home Farm was cleared of a thick accumulation of silt. This pond served a saw mill at Home Farm, operating since the nineteenth century. During a watching brief, Oxford Archaeology discovered six boards within the silt. These produced a date of c.1900, significant in that these planks had been pit-sawn, proving that this method of conversion was still in use to the end of the nineteenth century at Stowe, and that water seasoning, or steeping, was employed. In this method freshly sawn oak was submerged in running water for a time to flush the sap from the pores, allowing it to dry out much more satisfactorily during the subsequent seasoning.

STOWE, The Rotonda, Stowe House (SP 674 371)


(a) Dome reconstruction Felling dates: Spring 1751 and Spring 1752


Ribs (3/6) 1751 (21¼C); 1750 (19¼C)2. Site Master 1610-1751 STOWE1 (t=5.4 EASTMID; 5.1 ORIEL1; 4.6 MASTERAL)


(b) Repair phase Felling date range: 1779-1811


Repairs to ribs (3/7) 1776 (6); 1770 (H/S); 1769. Site Master 1683-1776 STOWE2(t=7.0 MASTERAL; 7.0 ssj51; 6.4 ORIEL1)


The extensive programme of restoration by the National Trust of the gardens at Stowe includes the garden buildings. One of the earliest buildings is the Rotunda, erected c.1720 and attributed to the architect, Sir John Vanbrugh. Archaeological recording and excavation has been carried out during major repairs, including dendro sampling. The felling date of 1752 accords well with a detailed series of building accounts for the gardens which suggest that between 1752 and 1754 the original domed roof was removed and replaced by a dome with a much lower profile. The lower sections of the ribs had been repaired with curved pieces of oak tenoned into a wall plate and secured to the upper sections with hand wrought nails. These produced an estimated felling date of between 1779 and 1811, showing that these repairs were much earlier than previously thought. As a consequence these timbers were retained in situ as important evidence of late eighteenth-century repairs. (Miles and Worthington 1998, VA 29, list 90)

STATS


(b) Moving and reconstruction Felling dates: Spring 1763


(a) Wall plates (2/3) 1701(2), 1704(h/s). (b) Purlins 1747(h/s), 1748(1); Principal rafter 1745(1); Tiebeam 1741(h/s); Rafters 1762(24¼C), 1753(12). Site Master 1610-1762 STOWE6 (t = 7.6 CRBCR2; 6.7 THEHOVEL; 5.6 STOWE2)


The two lake pavilions form a backdrop to the Octagon Lake, and are thought to have been built as two ‘heathen temples’ by Vanbrugh in 1719. In 1764 Earl Temple moved the two pavilions further apart to accommodate the great broadening of the South Vista. At this time the temples were improved by the addition of Neo-classical details by Borra. Dating commissioned by the National Trust during re-roofing works to identify how much of the original timberwork survived from the pavilion’s original construction. It appears that the majority of the roof timbers date from the Borra reconstruction, with only the wall-plates reused from the Vanbrugh period.

WEST WYCOMBE, 25 High Street (SU 830 947) 


(a) East cross wing Felling dates: Winter 1450/51


First floor joist rear bay 1450(25C). Site Master 1384-1450 wwa7 (t=7.1 MAGDALN1; 6.3 MDM; 6.0 MDM9)


(b) West range Felling dates: Winter 1530/31, Winter 1531/2, Spring 1532


Tiebeam 1531(19C); Purlin 1531(28¼C); Strut 1530(19C); Joist 1531(25¼C); Stud 1531(20C); Axial beam 1531(7¼C). Site Master 1395-1531 WWYCOMB1 (t=7.8 SOUTH; 6.7 MASTERAL; 6.6 MC19)


25 High Street consists of two timber-framed buildings. From the two-bayed jettied cross wing to the east, only one timber dated, all the rest of the timbers being very fast grown and unsuitable for dendrochronology. Whilst the 1450/51 felling date is consistent with the architectural style of the building, some caution should be used in interpreting this as a construction date for the cross wing. The adjoining close-studded range to the west probably replaced a hall range in 1532. An elaborate moulding just inside the western elevation suggests that it too was a jettied building re-faced in brick. Dating commissioned by Gary Marshall for the National Trust.
