and Integrated Concrete Formwork (ICF) with pros and cons discussed for each method. After much research it was decided to use a bespoke system by Beattie Passive; a unique and inno- vative building method using a timber frame structure, the first building system to achieve Passivhaus certification in the UK. This special timber frame construction allows
a continuous layer of insulation to pass from floor to wall and wall to roof, providing a complete thermal jacket to the entire building enclosure, eliminating the effects of cold bridging. This unique build system uses simple ‘off-the-shelf’ products, providing an economical and quick method of construction and doesn’t rely on specialist craftsmen. The unusual combined timber and concrete
suspended floor construction with ground beams on concrete pads proved to be particularly suit- able for the highly shrinkable clay conditions that existed on the site. Great attention was given to the detail of
airtight construction and final test results achieved less than 0.5 m3
/(h.m2 ) at 50Pa. in addition,
thermal image cameras were used to test the whole structure before being finally sealed. “We even have a double cat-flap system
using the external side door and interior hallway door to ensure no air can escape!” says Paul.
