Long Crendon’s High Street and the roads around the 14th-century courthouse are a conservation area containing some of the finest vernacular architecture in the Vale. Many properties are Grade II listed. The roofing stock reflects several centuries of building: Collyweston-type limestone slates on the oldest properties, hand-made clay plain tile on 17th and 18th century cottages, Welsh slate on later 19th century additions, and concrete tile on post-war infill. Each material requires specific repair knowledge, specific pointing mortars, and in some cases planning consent.
The village sits at a slightly elevated position above the Thame valley, with open exposure to south-westerly weather on the western and southern elevations. Properties on the north side of the High Street have north-facing pitches that accumulate heavy lichen and moss in the damp vale microclimate, and the organic debris from the village ’s mature elm and oak replacements loads valleys every autumn. Several Long Crendon properties also have lead-lined parapet gutters in original condition — these are high-value assets that should be maintained rather than replaced.
