The new day space has been placed at right angles to the original structure as a 'protecting arm' thereby forming an area of semi-enclosed courtyard used for outside eating in fine weather. The 'arm' is treated on the road side with a wall constructed with stone reclaimed from the surrounding garden and elements of disused wall elsewhere on the site. A clerestory allows the new roof form to 'peep' over the protective wall allowing light into the kitchen but maintaining privacy. In order to maximise sun-light entering the living room of the main house the glazing pattern changes to a deeper window with roof glazing over as a means of separating the new from the old. Between these two glazing elements is a small ventilation stack serving the cooking area of the kitchen, which punctuates the roadside composition. On the courtyard side the corner of the building opens up with a series of large doors allowing the family space to extend easily into the garden.
