The conversion of three individual apartments above a shared basement level into a single home in this Edwardian house. The original staircase had been removed to facilitate the conversion into apartments, and an extension had been built to incorporate an external stair. A new central entrance to the house was created which connects the three upper storeys with a new traditional timber staircase, lit by a new stained glass window and ridgelight. The new large side extension has a roof terrace above. The project involved highly skilled local trades to supply and install the bespoke joinery (wall panelling, staircase, parquet flooring, doors etc.), the plasterwork (cornicing which was based on the original cornicing where this was still in place) and stained glass which was made by a York based glazing company. All of the external windows were replaced with new locally made sash windows and the new doors into the garden are Crittall steel framed. The design incorporates the period features that would have existed originally combined with the luxuries expected in a 21st century house.
