About Tuffnells Way, Harpenden

Clarke and Whalen Architects were commissioned to design a single storey extension to replace an existing conservatory in Harpenden. The client wanted to create an open-plan Kitchen/Dining/Sitting area that created a fantastic connection with the garden, whilst improving the thermal efficiency of the house.

The flat roofed design allowed the incorporation of a large roof lantern which floods the internal space with light, this coupled with the large bi-fold doors and seamless corner windows created a bright familty living space. The extension also incorporates nice homely features such as a traditional Aga, a wood burning stove and wet underfloor heating to allow continued use throughout the seasons.
