P3r Engineers offer innovative design in building services and are energy and sustainability consultants. Founded by Michael Popper, formerly of Michael Popper Associates, we have been responsible for many award-winning projects with some of the UK’s leading architects, including four RIBA Awards in 2018. We have expertise in mechanical, electrical and public health systems, with particular skills in low energy and passive building environmental design. Our extremely broad experience covers the commercial, cultural, education, residential and institutional sectors, both new build and refurbishment (including listed buildings). From our offices in London, Rickmansworth and Belgrade, we are able to dedicate experienced engineers and director involvement through each stage of the project, from concept through to completion.
