Case Study of a CLT Passivhaus – Larch Corner, Warwickshire – Online

Event Details

 Registration is closed for this event

At the northern edge of the Cotswolds is the sleepy village of Upper Quinton – not the kind of place you’d expect to find a house that redefines the rules. A celebration of modern timber design and engineering techniques, Larch Corner is a timber lover’s dream. Almost all of this modern, three-bedroom, single-storey home is built of sustainably sourced timber, reducing emissions during processing and manufacture, and carbon emissions in use.

The structure is built from 35 internally exposed cross-laminated timber (CLT) panels, held together by 21,000 screws. With its Air Permeability of 0.041 m3/hr/m2@50Pa, Larch Corner is 195 times more airtight than required by the Building Regulations. Speaker Mark Siddall will reveal the design and construction process as well as the lessons learned from 12 months monitoring from Larch Corner, the winner of the 2021 Small Projects UK Passivhaus Award.
