The external design owes a lot to the work of Midcentury American architect Joseph Eichler. For more detail see here. We have just completed the full refurbishment of another 70's bungalow including upgrading of the fabric to allow heating by air source heat pump.
As well as local projects I've recently worked on buildings in South Gloucestershire, Stroud, North Wiltshire, Bath & North East Somerset, Berkshire and Wandsworth. I work on a wide variety of projects including listed buildings, new houses, residential extensions of all sizes, and commercial work. As far as possible and where relevant I use SIPS timber frame construction, as it provides a better job at a similar price to traditional construction while giving insulation standards way above current regulation requirements.
