We recently completed a full house refurbishment including a 4-metre rear extension, dormer loft conversion, and complete interior renovation with ALMO Property Group—and I genuinely couldn’t recommend them more highly. From the very beginning, the team managed everything seamlessly, from planning and design through to execution. What could have been an incredibly stressful process was made smooth, organised, and surprisingly enjoyable thanks to their professionalism, communication, and attention to detail. The quality of workmanship throughout the project has been exceptional. Every stage was handled with care, precision, and a clear commitment to delivering a high-end finish. The team were reliable, efficient, and always kept us informed, which gave us real peace of mind. A special mention has to go to Ameer, who was absolutely outstanding from start to finish. His dedication, responsiveness, and willingness to go above and beyond made a huge difference. He was always on hand to answer questions, offer solutions, and ensure everything ran perfectly. ALMO Property Group have completely transformed our house into a beautiful home, and we are beyond happy with the results. If you’re looking for a trustworthy, skilled, and professional team, I would highly recommend them.

Plastering- 26 Jun 2016
We hired Manu and his team to plaster our summerhouse, relocate two radiators and fit a new bulkhead ceiling in the lounge and install LED tape. He was knowledgable, professional and considerate and I highly recommend Manu and his team. Not only did he understand the project for the bulkhead, but he came up with another suggestion which we went with, and friends and family agree looks amazing. The finish on the plasterwork is perfect and Manu and his team worked hard and even left the summerhouse cleaner than when they started! It is great to work with a team who pay such attention to detail, listen to the client and get the job done to a high standard. It was a risk to go with Manu as he didn't have any feedback when I hired him. I actually got him to quote so I could compare prices with someone else I had in mind to do the job, but when I met Manu I felt he would be the better person to do the job as he listened and understood exactly what I wanted and so I ended up hiring him instead. I wouldn't hesitate to hire him for any future jobs. Thank you Manu and team!

Freddie, Kaz and Dan are a great team. I felt they were friendly and professional throughout. Any slight niggles were discussed and solutions found, quickly and professionally. They were respectful and went out of their way to get on with all the neighbours.

RS Building successfully delivered two full back-to-brick refurbishments and a new-build development for us in Greenwich, including demolition and construction of four new dwellings. Their level of workmanship is exceptional, and their attention to detail is second to none. As experienced property developers, we’ve worked with many contractors—but RS Building stand out for their reliability, quality, and professionalism. We have since recommended them to several colleagues, all of whom have been equally impressed. Our only regret is not finding them sooner. We look forward to working with them again on future projects.

An extension builder in Soho should have a strong track record with similar projects and relevant building qualifications or trade memberships, such as the Federation of Master Builders (FMB) or TrustMark.

Your Soho extension builder should ensure the project complies with Building Regulations and, where necessary, handle or assist with planning permissions. Ask how they manage building control inspections and what documentation you’ll receive once the project is complete.

What experience do you have with similar extensions in Soho?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Soho extension builder’s ability to deliver a result that meets your expectations.

How long will the extension take to complete?

Do you offer a guarantee for your work? Most Soho extension builders offer a guarantee or warranty on their work, often between 1 and 10 years depending on the project and materials used. This gives you assurance that any issues will be resolved after completion.
