Design and Build Companies in City of Westminster, Greater London Rated 5 Stars Only
Average rating: 5 out of 5 stars23 July 2026
“Homeconcepts completed a substantial rear and side return extension on our home in Fulham earlier this year. It was a complex build. Space was limited and there was a fair amount of planning permission and structural engineering to work through before anything could start. The site team, the project management and the quality of the finished work were outstanding throughout. Every detail has been carried out to a very high standard. We're genuinely pleased to hear that friends nearby are now bringing them in for their own renovation next year. We wouldn't consider using anyone else for future work. Couldn't be happier with the result.”

“I worked with Home Republic last year on a large extension and renovation project as the interior designer. The team were a pleasure to work with, very responsive to any queries or issues and their work was finished to a very high standard. I would definitely recommend their services.”
Aflux Designs
Design and Build Companies in City of Westminster, Greater London Rated 5 Stars Only
Average rating: 5 out of 5 stars29 May 2026
“We worked with Aflux on a complete strip-out and renovation of an apartment we purchased in Paddington, and we couldn’t be happier with the outcome. As first-time renovators, we were looking to create what could eventually become our forever home. The Aflux team guided us through every stage of the journey, making what could have been an overwhelming process feel manageable and enjoyable. With both my wife and I balancing demanding corporate careers and a pregnancy, having Aflux as a single point of contact across the entire design and build process was invaluable. Their transparency throughout the project was exceptional, and we greatly appreciated the flexibility they showed in working within the constraints and requirements we set. We had a very clear vision for the end result, and there were moments when we were prepared to compromise. To their credit, the team continually pushed to find solutions that delivered the outcomes we really wanted rather than settling for second best. A special mention goes to Tomaz and his build team, who were outstanding throughout the project and delivered exactly what we were looking for.”

Design and Build Company FAQs
In short, a design and build company consists of all stages of the construction process, from design to build, in one place. A design-build firm works under one contract with the project owner to complete both design and build steps of the project.

They will take on the responsibility of planning the project, drawing up the designs, costing, sourcing the building materials and supplies, building the structure, installing any permanent features and possibly advising on the interior design of your home; all while consulting you every step of the way.
Speed and cost. Hiring a design & build company for your City of Westminster project means that the whole process from start to finish will be quicker, as all stages of the project will be handled by one company. This also saves time finding additional companies to complete certain stages of the project and potential back & forth between builders and designers to discuss the plans.

By using a design and build company in City of Westminster for your project, you will also be given an all-in-one quote for the design and construction of your project. This is often cheaper than hiring separate professionals for each step of your project.
