Rafters (1/2) 1476 (4); Collars 1475 (1); 1474 (H/S); 1470; Principal rafter 1474. Site Master 1292-1475 FRDABBY1 (t=7.2 HANTS97; 6.9 SHERFLD; 6.8 ASTNEYR3); Wall plates 1485; 1483 (H/S); 1414. Site Master 1386-1485 FRDABBY2 (t=6.1 OVERTON3; 5.5 KENT88; 5.4 HANTS97)
In 1521 the last Abbot of Forde Abbey, Thomas Chard, succeeded and embarked on an ambitious programme of restoration and improvements to the buildings which was cut short by the Dissolution in 1539. In 1997 repairs were undertaken to the roof of the Library, converted from the monastic Refectory or Frater. This roof comprises 13 arch-braced collar-trusses with curved V-struts alternating with straight cross-bracing, sitting on inner and outer wall-plates above which are four tiers of bare-faced butt purlins and a ridge piece. The high quality of the carpentry is emphasised by the liberal use of mouldings and chamfers on all exposed structural members, with the unusual feature of three tiers of straight cross-bracing between the purlins with the collars, arch-braces and ashlars all having their faces elaborately carved with sunk blind-tracery. The roof has typically been ascribed to the fifteenth century on stylistic grounds, but due to its unusual design, this dating was tentative at best. Two estimated felling date ranges for the roof straddle 1500. Dating commissioned by architect Rebecca Child of English Heritage’s Conservation South-west Team.

The Riding House is rectangular and stone-built, approximately 33.5 m by 9.1 m, originally with two ranges projecting at right angles. The first documented purpose-built riding house in England was erected for Prince Henry at St James’s Palace in AD 1607–9, and other examples followed in the early seventeenth century. Wolfeton is rather narrower than most other examples, and it had a ceiling, where most were open to the roof. The previously suggested date of around AD 1600 is now confirmed and it must be very similar in date to the St James’ Palace example, and possibly slightly earlier. Commissioned by English Heritage.

CORFE CASTLE, Uvedales House, 17-19 East Street (SY 961 811), main range roof
Felling date: Spring 1656
Purlins (2/4) 1613, 1618(h/s), 1647(25); Principal rafters (1/3) 1655(33¼C), Rafter (0/1). Site Master 1505-1655 UVEDALES (t = 6.7 HANTS02; 6.1 WIN42HSB; 5.9 S.ENGLAND98)
This is an irregular L-shaped block on the east side of East Street, originally a merchant’s house. The roof has double trenched purlins with downward wind braces to the lower purlin, and queen struts to the principal rafters with a slightly higher collar, clearly designed for habitation. Two timbers, a fireplace lintel and a frame member in the rear wing (15 East Street) were sampled, but neither dated. Dating commissioned by the National Trust.

WIMBORNE MINSTER, Priest’s House Museum, 23-27 High Street (SZ 010 000)
(a) Main range
Felling date: Summer/autumn 1634
Purlins (1/5) 1600 (H/S); Strut/post 1634 (29½C); Principal rafters (0/2). Site Master 1259-1634 WIMBORNE (t=9.0 MASTERAL; 7.1 EASTMID; 7.1 GIERTZ; 6.5 OXON93)
(b) Cross-wing
Felling date range: After 1555
Tiebeams (1/2) 1480; Strut/post (2/3) 1534, 1545; Principal rafters (0/2).
The Priest’s House Museum, Wimborne Minster, is a grade II* listed town house of considerable quality and interest. It is of flint and stone construction and of several phases, the first of which appears to be the main range which runs parallel to the street. To the north is a cross wing of similar construction, and to the south a second cross wing which retains some timber-framing. These were thought to date from the 16/17th century on stylistic grounds. In front of the main range a second range was built in the 18th century bringing the building out to the line of the northern cross wing. The roofs of the first two phases both have double butt purlins with collars and tiebeams, the struts/posts rising from them to the principal. It was the objective of the tree-ring dating to determine the chronological relationship of the first two phases of construction. Although a felling date of 1634 was obtained for one timber from the main range, no sapwood was present on the dated cross wing timber, therefore only a terminus post quem of 1555 could be given (Miles, D H, 1994 The tree-ring dating of the Priest's House Museum, 23-27 High Street, Wimborne Minster, Dorset, Anc Mon Lab Rep, 39/94).
