Construct single storey rear extension to end-terrace house, 3m deep by 4.8m wide (full width). Existing rear door opening to become internal threshold into new room — no structural beam required.

Fit bifold doors across rear face. Pitched roof with skylight. Move back gate as required. Relocate or protect existing yard drain (serving downpipe and household waste) affected by build. Brickwork to closely match existing and tie into bond pattern — not butted (to match neighbouring extension on the opposite terrace - see photo).

Fully finish interior: plastering, electrics, heating, flooring. Building regulations compliance required.
