Rear, side and two-storey extensions

A terrace in Chiswick and a detached house in Ascot or Sunningdale are priced and built differently. The London job is usually tighter on access, party walls and parking. The Ascot or Sunningdale job is often larger, with more scope in the kitchen and the rear of the house.
