project Tanzarra

Demolition of an old build and the creation of a 2-storey 5-bedroom timber frame eco home built into the cliffs of the north coast of Cornwall

old build for demolition

Design and build by LionPark Construction

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 a 2 storey house. This project includes:

  • 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 a 140mm timber frame structure house was constructed with external block skin. Some steels were used to create large internal spans. Beam and block and glulams were also used to advantage to create usable internal spaces on a tricky sloping site. Posis joists were used for ease of first fixing.
  • The structure is topped by a flat warm roof construction, 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 recovery and ventilation system offer filtered air all year round.
  • ‘Tanzarra’ was constructed to strict airtightness and has achieved an 85B score for energy performance. It is a prime example of LionPark’s high quality workmanship and was a finalist in the LABC Building Excellence Awards 2014.
