Flexi House has very kindly organised an open day so you can visit one of our projects during construction. It is off-grid and targeting Passive House Plus certification.

The owners engaged Frank House to construct the shell of the building off-site, which introduced Flexi House to the project to undertake the DfMA (Design for Manufacture and Assembly).

Lots of things to see, hear, and learn from the project - do register and come along if it interests you.

All are welcome! - Architects, Designers, Engineers, Builders, Trades, Homeowners and Passive House/ Offsite enthusiasts! Spread the word.

We’ll begin with a walk around the house, meet inside for a talk and short presentation from a couple of key collaborators followed by Q&A.
