“Planning a loft conversion i was looking for a trusted builder for a while. Klisman was recommended by our neighbours, it was an excellent choice! The project moved very fast and his deep knowledge of every element in construction and energy proved to be incredibly valuable. His suggestions and recommendations were always spot on! The whole conversion was completed in the shortest span without any delays. I would strongly recommend Klisman construction for any building projects you are planning”

Why Clients Come Back
Good building is as much about judgement as workmanship.
Every property brings its own decisions. We bring practical suggestions, explain the options clearly and keep the work moving, from the structural stages through to the details you see every day.
Clients repeatedly mention the same things: attention to detail, straightforward communication and useful recommendations when a better way forward appears.

Client Reviews
Three reviews from homeowners who trusted us with significant work in their homes.
“Highly recommend Klismann and his team. Great attention to detail and workmanship. Klismann is refreshingly calm, open and honest and makes great suggestions for how things can be done better. Also takes the trouble to clean up at the end of a project. I was so impressed I hired him again for a another project. thank you.”
“I would thoroughly recommend Klis and his team - very impressed from start to finish. They knocked through an old load bearing wall, opened up our living/kitchen area of our old 1960's kitchen, installed new roof and skylights and completely transformed the space. We had a number of quotes/discussions with other builders, and from the start I found Klis the most responsive, reliable, prompt and trustworthy. He took the time to talk us through our options, and we could rely on the recommendations. I'd have no hesitation in recommending Klis and his team”
