Eco-friendly house extension using 5 panel bi-folding doors

This 1930’s Staffordshire family home has just been extended by the architect owner, Janes Architectural in Sutton Coldfield to provide a large kitchen extension and outdoor entertaining space using the SFK70 folding sliding door system.

The home already boasted a lovely long south west facing garden which the owners wanted to enjoy both visually and physically. The new kitchen extension is four times the size of the original kitchen and was designed so it would connect with the outdoor space, to not only enjoy the view but to also provide a large socialising space, especially when the bi fold doors are opened.

The design incorporates a hardwood deck which is  flush with the kitchen floor, the top hung system and flush floor track have allowed for a seamless intersection between inside and out with the doors open.

The house extension was designed to be as eco-friendly as possible. There is an overhanging roof to the rear (South West) elevation which helps prevent overheating in the summer but allows the low winter sunlight in. The kitchen floor is black slate and has a high thermal mass which retains the heat from the day and minimises load on the under floor heating system.

The customer chose Sunfold as they ‘offered the best overall value’. The SFK70 system was specified and incorporates a set of 5 panels, a set of 3 and a fixed panel with in-glazed venetian blinds. Chosen by the owner due to ‘the high insulation value of the thermally broken system together with high specification glazing, narrow sight lines and trusted German engineering along with a robust sealing system’.

The owners of the property are over the moon with the wow factor that the folding sliding doors have created in their kitchen extension. The doors are not only very aesthetically pleasing they are also extremely practical for family life. With a young child living in this property, she is fortunate to have the freedom to play outside whilst never being out of sight.
