Neil Mathews completes Belfast house extension

  • Comment

[FIRST LOOK + DATA] Neil Mathews Architects has completed this £90,000 extension to a semi-detached home on the outskirts of Belfast

Sitting within a street of semi-detached properties, the existing house has been extended both to the side and rear.

The 137m2 extension has increased the existing floor area by 165 per cent.  

Windows in the living room and master bedroom have been repositioned to give direct views of the nearby sea.

Architect’s view

‘We’ve placed a large rooflight in the grass roof to the rear to give light to the middle of the land locked site. The porch to the front reverses the notion of a street of brick with windows for light, by having a frameless solid door with the glazed walls coming to meet it.

‘The roof is a tiny thin blade of mirror polished stainless steel and the structure that holds it is hidden in the timber of the door. There’s also a single stringer walnut staircase which glimpsed through the porch forms the start of an intriguing view, culminating with the glow of light from the roof in the kitchen beyond.’
