Long Crendon Eco Home is a sustainable contemporary family home in the heart of Buckinghamshire. Constructed with Structurally Insulated Panels (SIPs), the house was made watertight in just one week, delivering exceptional environmental performance and energy efficiency. Natural, self-finished materials echo the simplicity of nearby farm buildings, whilst the interior’s fluid spaces are tailored to the family’s lifestyle. Delivered for under £1,500 per square metre, this project showcases Mailen Design’s ability to blend sustainability and innovative design with creative solutions that respect budgetary constraints.
