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."

"Expertise and good communication is what Alt Construction are known for and they live up to their reputation. Tommas is one of the owners and he personally project managed our side-return extension. He made sure we were happy each step of the way. They did an amazing job and also did little things like providing us with a temporary set-up: washing mach./dishwasher etc. This made living through the work less stressful. They delivered to their timeline and budget and made sure everything was expertly done. We’re planning future projects and will go directly to Alt Construction for this work."

"I'm really impressed with the workmanship of ALT carried out for our loft conversion. We didn't think we'd be able to create a good loft space but our architect advised us on the best design and ALT completed the project with very good finishes. They were always available to speak to us during the whole renovation and always took our ideas on board. They were not the cheapest, but we were really happy with the results and believe the cost was worth every penny. We were considering moving home but now we feel really comfortable as ALT have help create the sanctuary we now love to live in."
