Tanzarra eco home, Mawgan Porth, Cornwall

A 5 bedroom timber frame eco home built into the cliffs of the north coast of Cornwall

Heavy plant demolished an existing split level bungalow, crushing block and rubble for

use onsite. Excavations into the sloping site created the ability to build ‘Tanzarra’ as a 2 storey house.  

Strip foundations, preprufe membrane, 14 tonne of steelwork and approx 90 cubic metres 300mm poured concrete base, with starter bars were constructed first.  That allowed work on a single sided shuttered 2 pour (approx 100 cubic meters) retaining wall. From these heavy groundworks, the timber frame was constructed - a 140mm timber frame structure house with external block skin.  Some steels are used to create large internal spans.  Beam and block and glulams are also used to advantage to create useable internal spaces in a tricky sloping site.  Posis joists were used for ease of first fixing.

The structure is topped by a warm roof construction, flat, offering excellent insulation. 200mm celotex and a 200mm soil 'green' roof, using local grasses and fauna propagated onsite. Solar Thermal panels heat the passive house along with solar gain through triple plazed windows. A heat recover and ventilation system offer filtered air all year round.

‘Tanzarra’ was constructed to strict airtightness and has achieved an 85B score on its energy performance. It is a prime example of LionPark’s high quality workmanship.
