White is the building that was already there; mint is what we built: the rear extension and the side-return infill with its three rooflights, the folding doors, and the bathroom’s old door bricked up to a new window.
This is a ground-floor flat. The calculator prices work like it on the nearest house we draw, a terrace with a wraparound extension and a full renovation. Today’s guide prices, so your home and your job will differ.
The drawings
The whole flat at ground floor, drawn to scale from the architect’s planning drawing.
The back from the garden: 2,700mm to the roof behind a parapet, five folding door leaves.
Section A–A: how the two chimney breasts are carried on new steel.
The programme as issued: eleven stages across a five-month window.
