What can I build, and will it pay? The planning rules, what neighbours have built, planning decisions, energy upgrades, and whether extending pays.

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.
Planning applications outside London aren't published as open data yet, so search the council's own register: the drawings, the decision and the agent are there. Find the council's planning register on GOV.UK ↗

On these figures, moving loses about £15,732 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.
Where people extend most, and where the planning rules are tighter.
From energy certificates: an extension where a later certificate shows more floor space, a loft conversion where roof rooms appear.
