I have used Alt Construction on more than one property and was pleased to use them again for a flat renovation. They managed the works well, helped with sourcing finishes, and found a neat solution for some difficult downpipes by liaising with building management. Tommas, the site manager, was excellent throughout, coordinating everything and dealing with issues as they arose. His design choices were impeccable while respecting the budget. I’m very happy with the finished flat and would confidently recommend Alt Construction for full renovations. Communication was clear and timelines accurate.

A Reliable Team I Was Happy to Use Again

A few years ago Alt Construction completely renovated our house, including the extension, and we were very happy to call them back for a pitched roof leak repair at the rear of our property.
Once again, the team were professional, quick and very experienced. They completed the work with care and minimal disruption, and clear communication: we are very pleased with the result.
We definitely recommend Alt Construction for their professionalism, speed and expertise.

Roof repair

Last year we decided to have our attic space converted into a bedroom/bathroom and also have the existing bathroom completely redone. We employed a local architect (Elena Rowland, who I also highly recommend), who recommended Alt Group Construction for the build. It was a very good decision. The build was completed bang on time, it was within the agreed budget, and the workmanship was exceptional. The crew were highly experienced and a pleasure to work with. I highly recommend Alt Construction.

We hired Alt Construction for a complex renovation of a 100-year-old leasehold flat in central London. Despite strict conservation rules, freeholder constraints, and structural quirks, the team showed exceptional professionalism, skill, and patience. They tackled every challenge calmly, kept us informed at every stage, and delivered top-quality workmanship with rare attention to detail. Tommas, Karol, and Marcello were respectful of the building, neighbours, and timeline. We’d highly recommend them for any high-spec, high-complexity renovation project done right, on time, and with care.

We recently called Alt Construction again for a rear extension in Streatham, after they completed a fantastic loft conversion for us 3 years ago. As before, they handled everything—from structural work to plumbing, brickwork, electrical, fitting, and decoration. Tommas and his team once again delivered exceptional craftsmanship and professionalism, completing the project on time and within budget. We're thrilled with the results and highly recommend Alt Construction for any home improvement projects.


Happy Returning Client

Alt Construction, led by Tommas, did an outstanding job on the plumbing and fitting for our pasta bar, Nonna Mamma, inside Selfridges. They expertly followed Selfridges' internal guidelines, ensuring the work met all requirements while maintaining top-quality standards. The team was professional, efficient, and delivered the project on time and within budget. We couldn’t be happier with the results and highly recommend Alt Construction for any plumbing and fitting needs.
