What is under your new home on Peregrine Road

Congratulations on your move to Peregrine Road.

We checked the ground under your new home: no trees close enough to reach it, and satellite readings nearby show the ground has been stable.

The area is classed as likely to have had underground mining, which is worth a line in your survey and your buildings cover.

Captured from Homedata's API and Lead Source on 17 Oct 2026. Solar figures are estimates from the roof's size and pitch. Rent is an estimate from nearby lettings. Its listing photos were tagged by an AI image model, 30 Sep to 3 Oct 2026: room types read at 80% confidence or more; the model's other tags are not shown. Price growth is for the NR7 district, not this home: the median sold price over the year to 22 May 2026 against the year before, captured 18 Oct 2026. Trees, ground movement and clay from our ground stability data, captured 18 Oct 2026: tree heights are measured, root reach is inferred; ground movement is the nearest satellite reading, for the area rather than this building.
