What are the hidden costs of building with timber?

Potential additional costs include: structural engineer fees for timber design (may be higher than masonry if engineer is less experienced with timber), crane hire for panel/module installation, temporary weather protection during construction, specialist fire engineering for multi-storey, acoustic testing and certification, and airtightness testing. Most of these are modest (1–3% of total cost) and are offset by programme savings.
