House Extension in Oval — Rear, Side-Return & Wraparound
House extension around Oval (SE11) 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 Oval 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 Oval record headed “Central London proximity” belongs in the house extension brief where it intersects structure, weatherproofing, stairs or junctions, and consent path. That is a local reference often used when describing access, elevations or neighbouring fabric around Oval. We confirm fit, availability and written terms before any visit — Hampstead Renovations or Hampstead Maintenance, never a marketplace.
