Land Surveyor

A land surveyor is used to produce a survey of your existing site. This will consist of plans with levels (and elevations, if necessary) of your land, existing buildings, and/or any features such as trees, drainage, and different surfaces.

If you already have drawings of your existing house, or if you want a relatively small extension, you will probably not need to get a survey done, as most chartered design professionals can do this in-house. However, if you have a difficult site (e.g. awkward levels, disputed or unsure boundaries, tree conservation orders) then a full topographical survey will be necessary and will cost between £900 and £1200.
