House extension around Richmond (TW9) is reviewed for fit, fabric and current capacity before anyone is programmed. Rear, side-return and wraparound options scoped for structure, drainage, junctions and planning path. Period fabric around Richmond often means layered alterations, solid walls and services that have been changed over decades — structure, weatherproofing, stairs or junctions, and consent path must be read from the unit, not from the neighbourhood name. The Richmond record headed “Petersham Road” belongs in the house extension brief where it intersects structure, weatherproofing, stairs or junctions, and consent path. That is a street often referenced for Richmond (TW9). Confirm the exact unit — not the street label alone. We confirm fit, availability and written terms before any visit — Hampstead Renovations or Hampstead Maintenance, never a marketplace.
