This matters.

Caring for the environment and responding to the climate crisis are central to everything we do. That’s why sustainability is embedded in every project we take on.

One of the most effective ways we achieve this is through Passivhaus design—a rigorous standard that reduces energy use, cuts carbon emissions, and supports healthier, more comfortable living and working environments.

Passivhaus buildings are designed to dramatically lower energy demand, improve indoor air quality, and deliver long-term value through higher performance and reduced operational costs. They also help meet climate targets and raise the bar for construction quality.

We’re proud to be Certified Passivhaus Designers, helping clients create future-ready spaces that are as efficient as they are enduring.

What is Passivhaus?

Ultra low energy buildings which look and feel great

Passivhaus is an internationally recognised comfort and energy building standard which uses passive, low-tech techniques to drastically reduce, or eliminate, the need for space heating.

Passivhaus principles include significant levels of insulation, high air-tightness, triple glazing, minimal thermal bridges and mechanical ventilation and heat recovery to provide an exceptionally healthy and comfortable indoor environment with low running costs.

High level of continuous insulation

High level of Airtightness

Reduced thermal bridges

Triple glazed windows, focused on the views.

Efficient background ventilation with heat recover (MVHR).

Orientated for passive solar gain, whilst maximising views.

Our Approach

Imagine a building that offers both beauty and comfort, promoting health while operating at an ultra-low energy level.

The Passivhaus principles can be applied to any building type. With our design led approach, we integrate Passivhaus principles to create beautiful low energy buildings.

We have successfully designed buildings that meet the Passivhaus principles within Conservation Areas, adjacent to Listed buildings, on sites with challenging constraints and integrated modular construction methods.
