Quick answer
Builderr delivers side return and rear kitchen extensions across Hammersmith and Fulham — W6, W12, W14, SW6 and SW10. Typical H&F kitchen extension cost £60,000–£155,000 over 10–17 weeks including fitted kitchen. The deep Victorian closet-wing terraces of Fulham, Parsons Green, Barons Court and Brackenbury are textbook side-return territory: 1.4–1.8m side-return infill combined with 3.5–4.2m rear extension, structural ridge rooflight and Crittall W20 or Reynaers slim-frame sliding doors. Brackenbury Village, Bishops Park, Walham Green, Munster Village and Crabtree Estate CAs apply Design Code material rules — London stock brick (Petersfield / York Handmade), natural slate or zinc standing-seam, concealed parapet gutter, slim-frame steel rather than bulk aluminium. Brackenbury Article 4 direction removes most PD rights — every external alteration needs full planning. Determination outside CAs typically 9–11 weeks; pre-app advice (£290–£720) on CA streets routinely improves first-time approval. Fitted-kitchen spec from Plain English / deVOL / Roundhouse / Naked Kitchens determines £25k–£65k of the budget.
H&F Design Code (2018) requires 100mm cill, 35mm glazing bar and 6:6:1 sash proportions in CAs. RSJ structural opening of party wall £8,500–£15,000 with Victorian solid-brick propping methodology. Party Wall awards £900–£1,500 per neighbour, typically 2 awards on a side-return + rear combination. CIL H&F £180/m² Zone 2 (most residential), Zone 1 inner W6 £290/m².
