Mayfair is characterised by georgian townhouses, listed buildings, concentrated across W1J, W1K in the
Mayfair area. Mayfair is not uniform, but the georgian townhouses recurs often enough across W1J, W1K that the structural pattern is predictable once measured. Reading that across to Mayfair stock: georgian solid walls here cannot take standard cavity detailing, so Part L compliance is normally argued on a fabric-first basis with internal insulation and a condensation risk analysis. In W1J that determines the depth we can draw. Ridge and eaves lines along Mayfair streets are the reference Westminster City Council uses.
A Mayfair basement stands on its drainage and party wall evidence. If the W1J job later needs planning permission for W1J properties or loft conversion drawings, the existing drawings already carry the measurements.
What the Mayfair drawing pack contains
- construction floor plans for the Mayfair property
