Topsolve Building Solutions recently completed a full 5-bed HMO conversion for me in Doncaster, and the whole experience was excellent from start to finish. The team handled everything — structural work, gallow brackets, steel installation, electrics, plumbing and the full refurbishment — with great attention to detail.
Communication was clear throughout the project. I received regular updates, photos and breakdowns of each stage, which made the process smooth and stress-free. The final finish is exactly what I expected: clean, modern and built to a high standard.
If you are looking for a reliable builder for an HMO conversion, house extension or full refurbishment in Doncaster or South Yorkshire, I can highly recommend Topsolve Building Solutions. Professional team, good organisation and high-quality workmanship.

Topsolve have done a fantastic job at converting our garage into a living space, and joining it to the existing house, complete with flat roof and roof lantern. The fully itemised quotation was v. Helpful and competitive. Bart and his team are extremely hard-working, tidy and proficient. They made changes happily during the project, even when it meant extra work. The project was completed ahead of schedule and we are really pleased with the result.
