Dodden ltd, Somerset's eco builders have been specialising in low energy construction since 2009. We provide a full building  package through conception, planning, technical design and construction. 

Using advanced building methods to produce a very low energy building fabric. We are experienced in super insulated building elements, air-tight construction methods, and heat recovery systems. Our fabric first principals means important building junctions are meticulously designed to avoid cold bridging thus maximising the effectiveness of insulation, this coupled with our rigorous air-tightness methods and workmanship produces almost zero heating homes. We have achieved air-tightness test results as low as 0.22 m3/m2h @ 50 Pa.
Mechanical Ventilation Heat Recovery (MVHR) systems are essential to avoid condensation in very airtight homes and we are experienced in design installation and commissioning of these systems.
