What our clients say

You can check out more testimonials on our dedicated page.

I whole-heartedly recommend this building company. Avalon refurbished our grade II listed house in London. It was a six-month build. The refurbishment included removing all non-original additions, damp-proofing, structural work, completely new pipework and wiring, refurbishing original moldings and woodwork and external works. The quality of their work was outstanding.

My husband and I have worked with Avalon since late 2018 in preparation for an extensive 6-month home renovation that has just ended. From the beginning, Miros and his team were professional, responsive, friendly and so easy to work with. We felt that we were part of the process and that any questions or concerns we might have were always listened to. We were actively involved in the project and would visit the site regularly. All the builders on-site were highly skilled, hard working and unfailingly polite.

Avalon did a large, top to bottom refurbishment of my property and they were a pleasure to work with. Miros has assembled a great team who are either directly employed or are independent professionals he has worked for a long time. His in-house architect, Carlo, is a real pleasure to work with. They hit the ground running (a team of five arrived on the very first day) and did a thorough and high quality job. Miros is very innovative and I never felt that that I had less than his full attention. Best of all, they finished on-time.

"Now that practical completion has been granted I would like to thank you and your staff for the hard work that you have all put into this project. It hasn't turned out to be a very straightforward project as there have been so many late changes or problems but in spite of this everyone has worked extremely hard to avoid delays and to keep the project moving as fast as possible. The final job has achieved a very good standard in spite of these issues. I would particularly like to thank Yoanna Ivanova who has worked tirelessly to make sure everything was available in good time and has always responded very quickly to questions. She has worked extremely hard to get the project to completion and her efforts are greatly appreciated. I would also like to thank Stefan Ivanov who had to deal with the frustrations for constructing new areas then changing them on more than one occasion. In spite this he always kept smiling and was always positive. Overall I am very pleased with your performance and hope we will work together again in the near future."

Richard Gardiner

"We love the house, thank you so much for making it such a positive experience. We have been delighted with the quality and service that we have received from Miros and his company. The workmanship has been of a very high standard and the men have been polite and very industrious. They have maintained an impeccable level of safety and site house keeping, (even erecting temporary pegs for their work clothes). Miros has been personally involved at every step, listening to what we wanted to achieve and offering constructive advice and suggestions when unforeseen circumstances have arisen. The office staff have always responded in a timely manner to any emails and the after-service has been second to none. Miros uses specialist subcontractors such as glaziers and carpenters, who have worked with us in a similar manner. We would thoroughly recommend Miros and his company to anyone who expects a first class product and service."

Evelyn Rd, Richmond, London

"Having watched your team work for some months on this project I have been so impressed by the very high quality of their work, the very thorough and essential preparation and the care over every stage through to the finish which looks fantastic. The men themselves were always courteous and helpful even though they were working under quite difficult circumstances (Miros, I was so impressed by the way they would patiently climb down their ladders, move them and let our cars drive through the ‘tunnel’ promptly and without complaint, patiently then replacing the ladder and continuing with the work!)"
