House extension in North London using a small palette of simple inexpensive materials

The ground floor has been opened up and extended to provide one open plan living/dining/kitchen area with under floor heating. Three steel beams inserted at ground floor ceiling level are left exposed and painted a bright colour to delineate the ground floor space.

The kitchen incorporates a mobile unit with worktop/breakfast bar for greater flexibility of the open plan living area.

The first floor bathroom has been remodeled and two of the three bedrooms have floor to ceiling storage along the entire length of the party wall.

A new open riser staircase leads to the studio in the rebuilt roof space. Full height wall to wall glazed sliding doors and an internal glass balustrade fixed only at floor level give the unobstructed views to the rear. Internally a sliding/folding door divides the space to create a separately accessed guest room with ensuite shower room when required.

The original floor area has been increased by 50 per cent, achieved within permitted development limits, thus avoiding the need to obtain planning permission.
