Forest Hill side return kitchen-diner

Brief

A couple in a 3-bed Victorian terrace on the edge of Forest Hill conservation area needed a family kitchen-diner that worked for cooking, eating and homework — and a small utility room to take laundry out of the kitchen. The brief: side return extension under Larger Home Extension prior approval; integrated utility; landscaped garden.

Challenge

The property sat just outside Forest Hill conservation area — by 40 metres. PD rights were available but the planning route was attractive for design freedom. We tested both routes at feasibility: prior approval (6 weeks) for a 6m single-storey rear vs full planning (10–13 weeks) for a more ambitious wraparound. Client chose prior approval to save time. Neighbour to the south objected during prior approval period — required Builderr to manage neighbour communication and minor design adjustment to a side window to mitigate overlooking.

Solution

Side return extension 5.6m long × 2.4m side return width; existing rear elevation kept (no full wraparound). 1.5 × 2.8m roof lantern over the dining area; 4m wide aluminium bifolds to rear with thermally-broken frames. Compact utility room (2.4 × 1.8m) carved from existing kitchen footprint with full-height shaker joinery, Belfast sink and washer/dryer stack. Open-plan kitchen-diner with island. Landscaped garden including stone patio, raised vegetable beds and a small garden office (under 2.5m to avoid planning).

Outcome

Internal ground floor floor area increased from 52m² to 67m² (+29%). Utility room took laundry, recycling and dog bowls out of the kitchen — single biggest quality-of-life win. Prior approval granted after minor design amendment (side window to obscure glass). Total programme 18 weeks, on time and on budget. Garden office gave the parents a quiet WFH space.
