One firm across the whole build
Extensions
Rear, side-return, wraparound and two-storey. We take it from the drawings and building control through to the finished room — groundworks, structure, roof, openings, then the inside. On an older Surrey house the surprises are underground and in the existing structure, so the survey happens before the price, not after it.

Common questions
Q.01What does a house extension cost in Surrey?
It depends on the size, whether it is single or two storey, the specification, and what the groundworks turn out to be.
Q.02Do I need planning permission for an extension?
Sometimes, and sometimes not.
