We deliver high-performance Passivhaus and ultra-low-energy building consultancy for both new developments and transformative retrofits. With deep expertise in building physics and building services, we create spaces that are comfortable, efficient and exceptionally low carbon.

As certified Passivhaus specialists, we support every phase - feasibility, modelling, detailing, site delivery and final certification.\n\nBy embedding Passivhaus principles from the outset, we help reduce cost and complexity later in the process, enabling projects to achieve high performance affordably and without late-stage redesign. Whether it’s housing, education, labs or adaptive reuse, we ensure Passivhaus targets are met without compromise to architecture or function. Through rigorous analysis, fabric-first decision-making and integrated systems, we turn ambition into certified, world-class Passivhaus buildings.
