With any development, it is essential to be fully aware of all the costs of the self-build project at the beginning. Two of the most common items often not fully investigated are:
- Exact size and shape of the plot
- Slope of the site where the new house is to be build
Other constraints such as access positions, drainage and the location and height of adjacent properties are also recorded. Potton require a full measured and level survey (known as a topographical survey) of the site, including a Street Scene with levels to Ordnance Survey Datum.
The survey drawing will provide all the information & details necessary to enable Potton to accurately design & locate the new house within the plot and in keeping with adjacent properties.
The levels enables the slope of the site to be determined and these levels together with the ridge heights of adjacent properties enables a cross section through the site or a street scene to be drawn.
Local Authority Planning Departments now require that a topographical survey drawing, with levels, is submitted with the Planning Application.
If an existing property is being demolished, the Planning Department also require a floor plan and elevations of the existing property. The survey drawing is also used for Building Regulation Approval & enables the new building to be set out accurately.
