Extension, remodel & retrofit of a small cottage in the green belt
The original house is a T shaped plan that has been extended twice since the 1970s with a concrete blocked extension to the south and a rendered block-work extension to the North. Both of these extensions are of very poor quality and, not only fail to enhance the accommodation or the amenity of the building, but also detract visually from the site and the original building.
The proposal was to demolish the poor existing extensions and the “stem” of the T so that we could build a new, simple extension to the rear of the property that keeps a simple massing and greatly improve the internal spatial arrangement and the aesthetic of the house.
Internally, the service spaces sit against the front elevation and form a buffer against the noise of the busy road. There is then a central band of circulation and the main living and sleeping spaces are set in the new extension with a full height glazed slot that brings light and space into the open plan living, dining and kitchen area.
The construction of the new envelope with a concrete ground floor and SIPs panel walls and roof, provide good thermal mass, super insulation and excellent air-tightness. Within the existing space constraints, the existing shell also has hugely improved insulation and air-tightness.
The extension was originally to be clad in dark stained vertical timber boarding, but due to restrictive covenant issues this was amended to an insulated render system. This is complemented by new high performance triple-glazed windows for good comfort and low energy usage.
