Convert construction did a wonderful job transforming our Victorian property - Marek was creative and supportive throughout the building experience and took care to make sure we were aware of all costs and schedules. His team of builders were punctual, polite and hard working, especially as they had the added pressure of us living on site whilst the work took place. We are delighted with the end result and the faultless finish that Convert delivered and recommend them wholeheartedly.

We commissioned Convert to do an extensive renovation and refurbishment of a flat in a mansion block, which had significant constraints in terms of building rules and regulations. It was important to work with an experienced building company, and Convert exceeded our expectations. They were highly professional, results oriented, and helpful. Marek has a good eye for interior design solutions and came up with many creative options that we happily adopted. Convert's workers are all professionals and work to a high standard. Convert delivered the project on time and on budget. Overall, we were very happy to have chosen Convert.

Convert Construction undertook the building of a beautiful family home for myself, husband and three children. The project consisted of demolition of existing house and building new. The team were great to work with, always listened to our requirements and open to offering suggestions themselves. This was a large project which was carried out professionally, on time and on budget, with a high degree of skilled quality. I wouldn't hesitate to use Convert again should I do future builds.

Absolutely first class. We used this Acton company to complete our loft conversion down in Tooting (SW17) and cannot fault ANY part of the process. Our requirements were listened to very carefully and some great ideas and advice were suggested. The core estimate was very detailed and stuck to. The build was actually completed UNDER the estimated time (pregnant wife, birth imminent!). All staff (and these guys are Convert STAFF, not 3rd party contractors like other loft companies use) were very polite and helpful (and tidy!). The workmanship was faultless and the loft looks absolutely stunning. The whole process from start to finish was A+. Price was competitive. These guys should definitely be considered for one of your three estimates if you are considering a loft conversion in London. Message me if you have any questions - happy to be a reference for this company.

Flawless. Highly recommended. We have used builders before, but Convert Construction are in a different league. Very professional, very responsive, very nice and most importantly very high build quality. The team worked very well with other professionals, including our architect. We have since recommended them to others and we would use them again, anytime.
