Glass Extension and Basement Conversion, Bath

This property renovation in Bath was a minor Grand Design.  We created a luxury open-plan kitchen-diner with basement conversion, linked by a large, double-height glass extension.  We chose a stone coloured powder coated aluminium frame to blend with the existing building.

The home had several needs:  to replace a tired kitchen; to create a utility room for drying laundry away from the main living areas;  to maintain adequate storage; and to look ahead to the children’s teenage years, providing their own space in a basement.

Basement Conversion

We engaged an architect and structural engineer, along with Party Wall surveyor to obtain statutory approvals.  To meet the head clearance in the basement conversion we dug down a considerable distance to underpin the walls and install floor insulation.  We tanked the walls for water-tightness, and insulated to comply with building regulations.  The finished basement accommodated a temporary kitchen to allow the old kitchen to be ripped out.   The basement now houses a small home cinema and gaming area at one end and a utility space with laundry at the other.

Half height excavation under the remainder of the house provides substantial storage and accommodates the new condensing boiler. The frameless, low-iron glass balustrade maximises natural light for the basement room along with two side windows fitted just above ground level.  The basement was finished with a polished concrete floor overlaid on a wet underfloor heating system.

Open Plan Kitchen Diner

The kitchen design incorporated a flush-fitting induction hob, quartz-resin worktop, and timber shaker kitchen units in two finishes.  We fitted an aqua glass splashback with colour-matched switches and sockets.  With large porcelain tiles over underfloor heating, an anti-slip version of the same tiles extended to the patio.  This created a seamless transition between outside and in, making the whole space feel significantly larger.  Architectural plants in colourful planters with built-in lights stand on the patio.  We installed a multi-room music system to provide music in 5 separate zones throughout the house.

Home Office

One of the challenges of any side extension from a rear addition is to find a role for what was the previous dining room.  A standard side extension would have covered the dining room window to create a gloomy space.  Glass overcame this problem and the previous dining room was converted into a light, airy home office with views to the garden and river beyond.
