What Affects the Cost?
Extension costs in Godalming are shaped by build size (measured in m²), storey height, structural complexity, and ground conditions. Labour rates reflect South East demand and skilled-builder availability. Material quality, brick-matching to existing properties, planning permission requirements, and building regulation compliance add significant costs. Party wall agreements (often mandatory for semi-detached and terraced homes) involve surveyor fees. Site access, proximity to amenities, and seasonal weather also affect project duration and pricing.
Money-Saving Tips
Book extensions during winter months when builders have spare capacity and may negotiate rates. Choose standard designs over bespoke features; pre-approved party wall agreements save surveyor costs. Obtain three detailed quotes and compare specification carefully—cheaper isn't always better. Plan groundworks efficiently to minimise disruption and labour days on site.
