House Extension in Streatham — Rear, Side-Return & Wraparound

House extension around Streatham (SW16) 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 Streatham 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. House extension decisions in Streatham should treat “Streatham Common” as a prompt, not a survey: That is a local reference often used when describing access, elevations or neighbouring fabric around Streatham. We confirm fit, availability and written terms before any visit — Hampstead Renovations or Hampstead Maintenance, never a marketplace.
