Passive House:
Built for Comfort. Designed for Life.
Fairfield Construction is Marlborough’s leading company in building Passive Houses, the world’s leading standard in energy efficient construction.
A Passive House isn’t just a building - it’s a better way to live. These homes are built to the world’s most rigorous energy standards, giving you year-round comfort, lower running costs, and a healthier indoor environment for you and your family.

Our Passive House Approach
We work with experienced architects and designers to bring Passive House principles to life — combining precision craftsmanship, smart building science, and materials that stand the test of time. The result? A home that’s healthier, more comfortable, and far cheaper to run, with a smaller footprint on the planet.
Fairfield Construction has completed multiple projects that are certified to Passive House standards. The knowledge gained in conjunction with the completion of the Passive House Tradesmen course ensures that we are able to give professional advice and understand the importance of the critical details to achieve the most energy-efficient home possible.
Passive House Features
-
Every Passive House is carefully sealed to prevent drafts and heat loss. This creates a comfortable, consistent indoor temperature while keeping energy use to a minimum.
-
Walls, roofs, and floors are insulated to the highest standard. This keeps your home warm in winter, cool in summer, and energy bills low.
-
Specially designed windows lock in heat and reduce noise. They let in natural light while keeping the interior climate stable year-round.
-
Fresh air flows continuously without losing warmth. This system improves indoor air quality and reduces the need for heating or cooling.
-
Every junction and corner is designed to prevent heat escaping. This ensures maximum energy efficiency and comfort throughout the home.
-
We use detailed energy modelling to predict and optimise your home’s performance, ensuring comfort, efficiency, and minimal running costs.
