Architects who think in building science. For thirty years we’ve made performance the point of the building, then proven it delivers. Passivhaus design, certification, thermal-bridge and PHPP consulting, training and post-occupancy monitoring, under one roof, across Ireland, the UK and the world.

Full architectural service and masterplanning, designed to perform from the first sketch, at every scale, in every climate. The building physics that makes performance real, modelled, detailed, and independently certified at scale. We trained much of the industry.

Certified courses, CPD, and the ZEB Summit we founded and run. Post-occupancy monitoring that proves buildings perform, and feeds the evidence back into the next design. Every practice says “sustainable.” We design to a standard you can measure, then we keep measuring after handover, from single homes to 5,500-home towns.

We know what works because we measure it. We’ve trained much of the Passivhaus industry, every course grounded in real projects, taught by the team who wrote Ireland’s national Passive House guidelines. Take the four-minute benchmark →
