following the successful conversion of a townhouse in marlborough road, we were approached by our client to prepare designs for their recently purchased five-storey townhouse in onslow road. our proposals include: the full refurbishment of the interiors at each floor; opening up the lower-ground level and extending with a modern portland stone clad extension to create a generous open plan family kitchen, dining and living space leading to a newly enlarged terrace with steps up into the rear garden; as well as a modern steel and structural glazed home office at upper-ground.
