What do our Customers say about us?

  • The job was the loft conversion, extension and whole house refurbishment. Not only they are reliable and organized. Jonas is also very friendly and communicative person, which has made a real difference on this project whilst there were many ommissions on my side in planning, though he helped me out. I am very pleased with the end result and would recommend them to anyone.

    Amitabh Panjabi
  • The dedicated project manager helped me through the whole process of the new build house and was very communicative answering my emails and texts at all hours of the day. Additionally, I chose them because, out of all of the builders I asked to come and take a look at the work, they gave the most input and really helped me to shape what turned into the final result of high satisfaction.
    E. Tippelt
  • I am most impressed with the all-in-one service provision by this company, from start to finish project manager Jonas was able to facilitate the project realisation from ideas to making things work altogether the way I would like. It also meant some very big challenges to resolve and make it happen aesthetically and practically
    Roman Kit
  • Hansen&Co team were very helpful at every stage, making suggestions as well as accommodating my design requirements. Their work was excellent and was exactly as I wanted for a competitive price - I'm really pleased. They were neat and tidy, and they were simply very nice guys. I would recommend them without reservation.
    M Marie
  • Very high standard of workmanship with excellent attention to detail.
    Mrs Jones
  • Extremely professional and delivered a high quality job. My work involved council sign off which they undertook and they listened to and incorporated minor adjustments that I asked for during the project. Overall though we were very pleased with the work done and the price paid.
    Mr Cooper
  • The project looked to me very complicated having entailed 11 steel beams. However, it was very helpful that project manager Jonas had on hand the architect and structural engineer from his side, so all was smooth and professionally swiftly done, and also with a single point of call. Am very pleased.
    Thomas Killick
  • It is good to know they are aiming for perfection and will give the solution to building as well as design issues. They are truly versatile in technical knowledge, all in situ.
    Mr Grafton
  • I appreciate Jonas how professionally you approached the task and your team made the project come true just as you promised, I have already given your details to a friend who will be in contact
