Our System

Our Build System

We’re the first company in the UK to achieve certification for a complete Build System from the Passivhaus Institut in Germany. Our innovative construction method, patented in 42 countries, provides a continuous insulation layer around the core of a timber-framed structure.
Here are the technical details of our build system
Made In The UK

Simplifying Passivhaus

Traditional methods of construction create numerous joints between the floor, wall and roof. Each of these joints will inevitably lose heat. Our build system overcomes this problem and meets the rigorous demands of the Passivhaus standard. Our system is housed within a treated timber-frame structure to deliver a complete solution. High performance insulation material is injected into the floor, wall and ceiling cavities, to create one continuous insulated layer. No joints. No leaks.


The Beattie Passive build system has been used to build award-winning social housing developments.

The system is incredibly versatile and ideal for volumetric modular projects, such as this net zero scheme in Wales.

We’re passionate about Passivhaus and all its benefits. Over 1,000 people live in a Beattie Passive home.
