WE ARE

Chartered engineers providing innovative design & consultancy in building services engineering systems and sustainability

Founded in 2012, P3R is a practice of highly skilled mechanical and electrical engineers with collaborative and sustainable design values at its centre. With expertise in low energy, low carbon, and passive design, we aim to create buildings that work for their occupants and approach every project as unique. We are dedicated to providing the best possible energy performance using passive design principles and systems which are as simple as possible for the end user to operate and maintain.

Over the years, we have forged strong and lasting relationships with building design teams and clients, and continue to be recognised for our committed understanding of project aspirations, openness to design dialogue, high standards and sustainability focus. 

Our broad experience covers both new and existing buildings, and many listed properties, across diverse sectors including residential, commercial, culture and education. We have worked with many of the UK’s leading architects and have been involved in several innovative and award-winning projects.
