Passivhaus Builders In Cambridge

We are a bespoke building company offering a gold standard building approach to passivhaus and eco friendly construction, in addition to our high quality traditional builds.

Discovering Passivhaus and the future of low-energy building?

These 5 Passivhaus principles are key to providing comfort, energy efficiency and durability.

Built to the highest of standards Passivhaus buildings consume up to 90% less heating and cooling energy.
However even if you’re not building a certified Passivhaus project you’ll still see enormous benefits in implementing these important principles.

If you’re looking to build a Passivhaus or want to explore more about how these building principles can significantly improve your homes efficiency please get in touch, we’d love to hear from you.

We are proud to be a certified member of the Passive House Institute, a globally recognised organisation committed to energy-efficient building standards. This certification reflects our dedication to sustainable design, high performance construction, and environmental responsibility. As part of this international network, we stay at the forefront of innovation in low-energy building practices, ensuring every project we undertake meets the rigorous criteria of comfort, quality, and exceptional energy performance set by the Passive House standard.

Airtight Installation

Precision sealing eliminates drafts, reduces energy loss, and maintains consistent indoor temperatures for ultimate comfort and efficiency.

Glass-to-Frame Ratio

Optimised proportions balance maximum natural light with superior insulation performance for year-round energy savings and daylight comfort.

Solar Gain & Orientation

Strategic placement captures winter sunlight for free heating while minimizing summer overheating through intelligent window positioning.

Thermal Bridging

Specialised installation prevents heat leaks at window edges, eliminating cold spots and boosting overall building energy performance.

Passivhaus window principles

Airtight Construction

Precision-installed windows create a complete air barrier, eliminating drafts while reducing heat loss by up to 90% for year-round comfort and energy savings

Triple-Glazed Glass

Three protective glass layers with inert gas filling achieve U-values below 0.8, providing superior insulation and noise reduction compared to standard double glazing.

Thermal Bridge-Free Installation

Special mounting systems and insulation wraps eliminate cold spots around window edges, preventing energy loss and maintaining consistent interior wall temperatures.

Thermally Broken Frames

Advanced window frames with insulated barriers prevent heat transfer, maintaining interior surface temperatures and eliminating condensation risks in cold climates.

Solar-Optimized Placement

South-facing windows maximize passive solar gain in winter while strategic overhangs or coatings prevent overheating during summer months for balanced thermal performance.

Smart Shading Integration

Automated or fixed exterior shading systems work in harmony with glazing to control sunlight penetration, reducing cooling loads by up to 30% annually.
