This is By extending across the full width of the house a new linear space approximately 2.5 metres deeps is created as a gallery which links the three main rooms of the house. To the West a projecting wing contains a new garden room which accommodates a bar with direct access to the terrace. The swimming pool wing will be altered to have new openings with sliding glazed screens similar in scale to the rest of the proposed. On the first floor there is no change to the room layout or window openings. The main change is the creation of a large first floor terrace extending across the full width of the house as it did when the original house was built. All existing windows will be replaced with polyester powder coated aluminium frame windows.
