McGuinness are an architectural practice based in central London. At the core of our practice is the understanding that good design has the potential to enrich lives. This means that whether you require a kitchen extension, basement excavation or a completely new-build, your needs and a solid understanding of how you will use the space we have created for you are central to our design process. We are friendly and open-minded and will take a brief and run with it, delivering innovative and creative solutions that are practical, but never run of the mill.

We work with both the private and public sectors in the UK and abroad. We have amassed decades of experience navigating tricky planning situations, pushing boundaries and keeping up with the UK’s ever changing design and development scene.

We specialise in basement excavations, extensions and air-rights developments. Effective use of computer-aided design, along with intimate knowledge of the planning and policy context in which we work, means that we have an exceptional track record of achieving successful outcomes in particularly challenging planning situations.



Will McGuinness


Will studied at The Bartlett School of Architecture, graduating with Commendation in 1994. Following his studies he worked for world renowned architectural practices including Foster and Partners, HOK Sport and Arup before helping to set up uvarchitects in 1998.


β€œWe engaged Will McGuiness on the renovation of a Victorian House in Wandsworth. The project involved the demolition of the rear back addition and replacement with a new extension with roof lights and bi-fold doors and a new terrace. The project also involved creating a dormer window in the roof, installing 2 new bathrooms and a downstairs cloakroom/utility, installation of underfloor heating to the ground floor and a new boiler and megaflow system. Will was brilliant throughout the project. I cannot recommend him highly enough.”

β€œMy wife and I chose Will McGuinness on the recommendation of our structural engineer and after interviewing two other highly regarded local architects. We got on well with Will right from the start of the project, a major renovation of a very tired 1960s bungalow which lasted from Nov 2015 to February 2017. Will came up with designs which immediately appealed, solutions to problems and tight project management with our builders, who he knows well and who we also got on with extremely well. We are now settling in to our beautiful new downsize home, and loving it. Everything works as planned, the standard of the work is very high and we are delighted. Well done Will, his assistant Harley and the team.”

β€œWe commissioned Will McGuinness to assist us with a wholesale remodelling of our two-storey, semi-detached house, including a large ground floor and first floor rear extension. He knew exactly how to get the most out of the build for us without creating issues with the local planners and was always on hand to guide us through legal and technical aspects of the project as they arose. Communication was straightforward and the process of getting to the point where works commenced was creative and enjoyable. We have now moved back into the house of our dreams and appreciate just how invaluable the UV’s knowledge and advice were. For example, who would have thought we could be so enamoured by an enlarged first floor landing which they somehow magicked out of v limited space?! I would highly recommend them.”
