A wraparound extension combines a side return and rear extension into a single L-shaped footprint. It's the largest possible single-storey ground floor on a Victorian or Edwardian terrace and turns the entire ground floor into an open-plan family hub — kitchen, dining and living rooms all flowing into each other with full garden views.
Every Redbridge project includes a free desk-based planning assessment before we quote. We know the local planning officers, party wall surveyors and approved inspectors by name.
