How you own it

Leasehold, over 300 years leftLand Registry title LA181059You own the property but not the ground under it. The lease runs so far beyond a normal lifetime that it behaves much like freehold, though the freeholder is still worth asking before structural work.

Your plot

213m²33% already built onThe land your house stands on. About 143m² of it is still open ground, and anything you build has to fit in that.

Garden depth

Roof height

Worth knowing before you plan work

• Very low from rivers, medium from surface water. That does not stop you building, but the council will want to see how floor levels and drainage handle water before they sign it off.
• The title carries a flood constraint, so the council will want to see how a new floor level and drainage deal with water.
• The plot falls in an SSSI impact zone. SSSI stands for Site of Special Scientific Interest, a protected piece of nature nearby. The zone means the council consults Natural England about large schemes; a house extension is not usually one of them.
• This is a radon area. Radon is a natural gas that rises out of the ground across much of the country. If you build a new ground floor, the builder lays a sheet barrier under it, which is a standard part of the job rather than a complication.
