PH15 Construction System

The PH15 System timber frame solution provides a Passivhaus suitable construction system that enables the build team to achieve airtight and thermal bridge free houses as simply and cost effectively as possible, supported with appropriate training modules.

The PH15 System is flexible enough to enable bespoke designs and to meet the many and varied planning requirements in the UK.

It comprises all the component parts needed to create a weathertight, airtight shell to the Passivhaus standard. By choosing to build with PH15 you can address the RIBA 2030 Climate Challenge Targets today. PH15 easily achieves this level of performance using timber based materials that sequester carbon.

For anyone wishing to design their own home or housing project using the PH15 System we have developed an Architect’s Design Guide. For more information and to view some of our latest projects please visit our Passivhaus Homes web site
