We are committed to helping clients achieve and exceed their responsibilities in reducing carbon emissions and delivering the most sustainable low-energy buildings possible. We have a firm belief in the simple concept of "Long-life, Loose-fit, Low-energy" pioneered by RIBA-president Alex Gordon almost 50 years ago, but which is more appropriate today than ever.


Many of our clients are passionate about the environment, such as The Wildfowl and Wetland Trust (WWT Consulting), and CABE (The Chartered Association of Building Engineers), and we have been fortunate to undertake research and develop ideas on their projects which then inform and feed into our other work. We are particularly interested in how sustainable principles can align with good economic principles and we look carefully for these opportunities and ensure they are optimised, as it is our belief that good sustainable design can and should have multiple benefits.

We prefer simple systems to reduce energy use, such as good passive design achieved through intelligent computer modelling, careful material selection and detailing, and robustly following the principles of reduce, re-use, and recycle. We are particularly interested in how embodied carbon may also be reduced, in addition to operational carbon, and the rapidly emerging field of whole life carbon analysis.

On all our projects we employ passive measures such as optimising insulation performance, reducing air leakage, managing solar gain and optimising natural daylight, to ensure we provide healthy and comfortable environments. Beyond the passive measures we consider renewable energy sources, such as solar panels or heat pumps, deciding on the most beneficial approach through a careful process of analysis and cost-testing. We installed our first ground-source heat pump over 10 years ago, at Burgess Farm in Essex, and since this time have gained further valuable first-hand experience in the installation of air-source heat pumps and solar photovoltaic panels.

We work closely with our clients to examine in detail the options available to them so that they can fully contribute to reducing their impact on the environment, meeting and often exceeding, their environmental obligations.
