Specialists in Low Energy and Passive House Design

In 2012, FmK made the move towards Low Energy Architecture and in 2015 the two directors trained to become Passive House Certified Designers and in 2018 also trained for Passive Certified Tradesman for hands on experience.

The Practice has close-knit contact with a range of highly skilled consultants used for support in designing your dream low energy builds such as structural engineers and SAP Assessors. We take great pride in the level of work we produce and are client centred on our approach to their projects with end satisfaction the main goal.


FmK have an extensive experience on site with our low energy designs and have developed and perfected our detailing for Low Energy and Passive Design. As leaders in the energy efficient field, we do not expect our builders just to “sort things on site” such as airtightness or thermal bridging details.

We have designed and developed all our own air-tightness details with practical on-site application in mind with on-site training of the contractor as an integral part of the process.

We have also Thermally Modelled all our construction details to ensure that they are Cold-Bridge-Free and designed them to be straightforward to construct on-site.

FmK also design the MVHR layouts and positions with the buildings to ensure maximum efficiency and logical installation solutions. 

As the airtightness results we are expecting are critical to the Low Energy or Passive Home, FmK conduct our own intermediate air pressure test with our own equipment to find any issues before the construction moves on too far, as leaks when the project is completed cannot be remedied. 

At FmK all the elements of the design are analysed carefully for their performance to ensure that as well as a beautifully designed home, our clients are also building a highly energy efficient building that will be very cost effective over it's lifespan.
