Refurbished bathroom extension to a grade II listed terraced house

The house on Kelly Street, North London, built circa 1855, is a Grade II listed terrace and is a fine example of 19th Century domestic architecture.

The existing rear extension was in a very poor state of repair, inadequately insulated and badly equipped for its use as bathroom accommodation.

The works were solely to the existing rear extension where the internal layout was rearranged to create a fully functioning bathroom and utility space. The buildings listed status necessitated the retention of the existing masonry walls.

These were insulated on the outside to maintain the existing, limited internal floor space, and clad in Oak boards of varying widths

The green roof has two motives. One, to create a more desirable outlook from the upper windows. The other to create a unique habitat on the building demonstrating that small-scale bio-diverse schemes that can be viable and effective.

Internally a Japanese style bathtub has its own low corner window with views of the courtyard garden.
