We have recently obtained planning approval for a new extension to an existing semi-detached house in Bradford-on-Avon. The existing house is yet again part of a typology of 60’s/70’s houses that exist up and down the country and one which we’ve enjoyed exploring. The typology is efficient in its layout and provides for good family space, but it is all too often disappointing in its architectural ambition providing social spaces that are un-fit for contemporary family life, with poor connections to the garden, and poor levels of energy efficiency.
These types of properties typically fall into the category of permitted development rights and our proposals sought to combine these with the already existing parameters in the neighbourhood where more than 50% of the area have added two storey side extensions. This provided a great starting point for considering volumetric constraints.
We used these constraints to model a side and rear extension that remains subservient to the original house, whilst reading as a contemporary new addition. The pitched roof of the extension is asymmetrical to allow us to tuck a study into the apex of the roof whilst providing a generous, part double height, kitchen/dining to the ground floor opening up to the garden. To the first floor 2 new bedrooms will be added with the connection corridor overlooking the kitchen below creating a sense of connectivity between the floors.
We will be using a combination of brick and timber to emulate the colours of the existing re-constituted stone but allowing the new extension to have its own identity. All existing windows will be replaced and new loft insulation added, which, together with a deep terrace providing solar shading to the ground floor, will significantly improve the energy performance of the whole house.
We are very proud to have won this planning approval despite receiving a lot of objections from neighbours. In fact, our proposals were highly commended for its modern design by Wiltshire District Council whom we worked with closely to fine-tune the proposals to ensure they were within acceptable massing constraints.
