Quick answer
Builderr delivers garage conversions across Hammersmith and Fulham — W6, W12, W14, SW6 and SW10 — £28,000–£65,000 typical. The borough's mix of Victorian terraces (Brackenbury, Parsons Green, Hurlingham) with no integral-garage stock and 1930s-onwards semi-detached and detached stock (Ravenscourt Park, Bedford Park fringe, Crabtree) means projects split roughly 60% mews + coach-house conversion to 40% integral 1930s garage. Build programmes 5–10 weeks. Mews conversions in Brook Green and Sulivan Court need full planning + change of use.
H&F has multiple mews streets (Sulivan Court Mews, Brook Mews, Wood Lane Mews, Verbena Gardens) where garage-to-habitable conversions need full planning + change of use B8→C3 + sometimes LBC where group-listed. Brackenbury (W6) + Crabtree (SW6) conservation areas restrict front-elevation alterations. Mansion-block parking-bay-to-storage conversions in earls-court-fringe SW10 + W14 Olympia need Licence to Alter from the landlord — typically not granted for change of use, only for internal storage upgrades.
