## Mortgages for wood-clad and non-standard construction barn conversions

Barn conversions and wood-clad houses are mortgageable, but they are often classed as non-standard construction, which reduces the pool of willing lenders. Non-standard construction means the property differs from conventional brick or stone walls with a tiled or slated roof, for example timber cladding, steel portal frames, or large glazed sections.

Lenders differ widely in how they treat non-standard elements. Some accept timber-clad barn conversions without issue where the underlying frame is sound; others restrict lending or require additional survey evidence. The valuer’s comments on construction, condition and re-saleability usually drive the decision, which is where whole-of-market advice adds the most value.
