What building regulations drawings cover in Richmond upon Thames
Planning permission decides whether you can build; the Building Regulations decide that what you build is safe, warm and sound. They are two separate approvals, run by different bodies, and a Richmond upon Thames project usually needs both. The building regulations set is the technical layer beneath the planning drawings — construction sections, structural details, insulation build-ups and fire-safety provisions that a builder works from and a building control surveyor checks against the approved documents.
In practice that means Part A structure — beam and foundation details with the structural calculations behind them; Part B fire — escape, protected routes and, in a loft, a fire door and mains-linked alarms; Part L conservation of fuel and power — U-values, insulation and airtightness; plus drainage, ventilation and stairs. On Richmond upon Thames's stock, which runs to Victorian and Edwardian villas and terraces, Georgian houses near the river and interwar semis in the outer wards, the recurring challenge is meeting Part L in solid-walled period houses without ruining the room, and we detail the insulation to hit the numbers with the least intrusion.
Building control applies everywhere in Richmond upon Thames regardless of planning designation, but in conservation areas such as Richmond Green, Twickenham Riverside, Kew Green, Ham Common and East Sheen (Sheen Common) the two processes interact — insulation and window details often have to satisfy Part L and a planning condition at once. Richmond is one of London's most conservation-heavy boroughs, with widespread Article 4 directions — on many streets even minor external alterations that would be permitted development elsewhere need a full application. We draw the construction details to reconcile both.
