Formed in 2008, Summerhouse Architects is an RIBA Chartered Practice with a successful track record working on a wide variety of residential and commercial projects. In 2014 the practice became a limited company and in 2016 we moved into our purpose-built studio at Mill Farm, Guisborough, allowing us to expand.

From transforming a derelict Grade II listed barn in a National Park to the renovation of a disused industrial unit to a large new-build family home, our clients can expect a quality service where design and attention to detail really matter.
