Removal of existing glazed roof to ground floor room. Installation of high level window. Build first floor extension matching existing roof line. New roof light. Re siting of gas boiler from bathroom to loft. Installation of new window to bathroom. Create new door opening in existing bathroom window location into extension. Create new door opening from bedroom into extension. Build partition wall in extension. External insulation to ground and first floor rear elevation. Two new roof lights to existing roof.

This is mid terraced and there is a party wall at ground level with neighbors ground floor room.

This extension will have two new walls one continuing the first floor wall of the bathroom and a return over the party wall. It is squaring the building at first floor level over the "missing corner"

Hope this makes sense. Regards John
