Across England and Wales, homes extended by a typical 30 m² and then resold rose about 11.1% more than similar homes nearby over the same years (124,884 resales); in West Midlands, 8.9% (9,962 resales).

| Stamp duty on the new home | £7,550 |
|---|---|
| Estate agent on yours 1.2% + VAT | £4,176 |
| Solicitors, buying and selling | £3,000 |
| Survey | £600 |
| Removals | £1,500 |
| Money gone | £16,826 |
| Building, plus 15% for design, planning and contingency | £57,500 |
|---|---|
| Less what it adds to your home's value 60% of the local price | −£36,600 |
| Money gone | £20,900 |
On these figures, moving loses about £4,074 less. Moving also changes the area, the schools and the commute; extending means months of building work and depends on planning.
Building costs vary a lot (a single-storey rear extension is often £2,000–£3,000 per m², more in London). How much space adds depends on the home and street: what extensions added to resale prices. A guide, not advice; nothing you type leaves this page.

Not every extension shows here. We only see building work when a new energy certificate is lodged, which happens when a home is sold, let or newly built. A loft or extension added since then won't appear, even with planning permission and building control sign-off, because those records aren't published as open data outside London. Missing work doesn't mean missing paperwork.
From energy certificates: an extension where a later certificate shows more floor space, a loft conversion where roof rooms appear.
