This is a creatively designed, single storey dwelling in form, with a shallow pitched roof. It has most of its glazing in the
southern and western elevations. It is built using the principals of sustainablility as reqired to be part of the 
Whiteway Coloney, Cotswolds


A luxurious waterfront house with about 7,000sq.ft. of pristine very high quality accommodation, and huge glass fronted deck; giving elevated views over the creek and Fal Estuary. Very energy efficent including photovoltaic panels on rear.


Three Mile Beach is a collection of 15 luxury self-catering beach houses located in St Ives. These are very high specification holiday beach houses, built to be energy efficent. Materials include timber frame, cedar cladded,  with sunken cedar hot tubs, barrel saunas, and wine cellars.

A quality, thermally efficient dwelling,  with a contemporary feel in Padstow. A great use of grey standing seams which can be a cost-effective alternative to copper and zinc. This can also significantly reduce the overall height of a building project, and extends the design possibilities.

This build was geared towards Passivhaus level, and  includes exemplary levels of insulation and incorporates techniques for generating, conserving and storing its own energy which is generated on site.  Logix Insulated Concrete Forms were also used for this ultra-energy efficient home.

 The philosophy was conservation of fuel and power and the generation of energy from renewable sources for this woodland home. Built as a simple timber frame dwelling using Epiphytic Bromeliads (air plants) on the roof,  the hope is for a return in investment within 10 years!
