HEM Architects

"I used HEM to design changes to a house that I was in the process of buying. Throughout the process everyone involved provided excellent service and developed a plan which met my stated requirement. Their processes ensured that I was fully up to date with both costs to date and the projected whole project cost. This clear visibility enabled me to see early in the project that my ideas for the house were not financially sensible and so I decided not to go ahead. This reflected no criticism of the service that HEM provided. Thanks to their professionalism I avoided making a big mistake. I can recommend them as a safe pair of hands."

"We recently had one of Hem Architects’ team, Josh, visit for a consultation on a rear extension and full house reconfiguration. The meeting was incredibly helpful—Josh really took the time to understand what we love about our home and what we want to achieve, then shared plenty of brilliant ideas we hadn’t considered. Their designs are creative, thoughtful, and practical, and the service is consistently top-quality. Whether you’re planning a full extension, a house upgrade, or just looking for expert guidance to develop your ideas, I can’t recommend the Hem team highly enough."

"We recently worked with HEM on a project that included designing a new extension, reconfiguring our downstairs layout for better space use, and developing a comprehensive retrofit strategy. The design solutions they proposed were creative and thoughtful—many of the ideas, including some really fun and unique features, were things we’d never have thought of ourselves. The retrofit involved improving insulation and airtightness throughout the house, installing an air source heat pump, and implementing other measures to significantly boost energy efficiency. The team at HEM were incredibly knowledgeable and supportive throughout the process. Their guidance was invaluable in helping us make informed decisions, and the results have exceeded our expectations. We've already noticed a major difference—our home stayed warm and comfortable during recent cold snaps, and during the latest heatwave, it remained cool and pleasant inside. We can highly recommend HEM to anyone considering energy-efficient home improvements or a retrofit project. Their expertise and thoughtful approach truly made a difference. Thanks!"

"Worked with HEM architects on a retrofit of a house from the ~1980s. Things went smoothly and they suggested a very good building team (edited: Walker Build Ltd). Very professional, helpful and pragmatic. It was easy to discuss ideas and boundary conditions of the build. Would recommend. The goals of the retrofit were reached in terms of energy savings. (edited by adding the following text in response to the request from HEM): The works undertaken were: - draft proofing, attic insulation, cavity insulation and outside wall insulation (15 cm), installation of triple glazed windows. - Installation of a heat recovery ventilation system - Moving of a door+additional window (this was to better use the space) It looks like we have been able to reduce our gas consumption by at least 50% (though that will need to wait probably until May to know exactly). Note: We did not change our average house temperature (~19 degr Celsius) and also exchanged out gas stove for an induction stove (so had a small increase in electricity consumption). The air is always very fresh and the humidity on a much smaller level than before."

"With a difficult planning process for a site in 'countryside', PTA designed an innovative house exactly as requested - despite some of the quirkiness we required! After initial rejection, the appeal was successful and it was a pity we couldn't find a builder to commit to a price and build it! Jess at PTA was very helpful throughout."
