Plans first, then the rear extension
Planning to enlarge the back of a Pinner or Hatch End house? The extension drawings can only be as accurate as the plans beneath them, so the survey comes first and costs from £200.
It returns existing plans of the house as built, to scale, and no opinion on condition. Read about rear extension drawings for the stage that follows, or the measured building survey service itself.
