What data is included?
- The height of the roof above ground level, both the highest point and a typical roof height.
- The roof type: flat, pitched or a combination.
- The volume of the building and the area of flat and pitched roof sections.
- The area of walls the building shares with neighbouring buildings.
How reliable is it?
The values are calculated from a point cloud of laser height measurements and are therefore indicative. Dormers, chimneys and trees can affect the results, and a recent renovation may not yet have been measured. The year of measurement is shown with the data.
What is it useful for?
Shared walls say something about heat loss: a mid-terrace house loses less heat than a detached house. The roof area gives a first impression of the space available for solar panels, although an on-site inspection is needed for proper advice.
