Ground floor back extension, reconfiguration and full redecoration. We chose Dali, firstly through recommendations by neighbours, seeing his work first hand and feeling confident during the consultation phases of his ability to deliver. Prior to the job commencing a schedule of works and costing were clearly agreed. We were impressed with Dali's level of communication and his availability to meet with us personally. He would always return a message promptly and that continued throughout the job. Dali expertly guided us through the project and also arranged architect and structural drawings, site surveys, council applications and 3rd party wall advice. We decided to live-in during the build which is never ideal but Dali cordoned off spaces for us to live whilst allowing him to get on with the job. He set up temporary kitchen and laundry facility some 3 or 4 times for us! Now for the business end. Dali supervised the project but also allocated a Manager, Michal to be our point person and he was on site every day without fail. Both would respond to any question promptly and courteously. I learnt to keep the questions short and be more patient as the job progressed as everything was always on their agenda to be done. Teams of builders would arrive punctually by 8am and work would always start promptly. Everyone on the team had clear instructions and their industry was on show from start to finish. I could not fault them at all for their reliability and professionalism. They were all courteous, polite and respectful and would also make a point to clear up after themselves at the end of each day. On occasions I did request a deviation it was fully discussed so we could make informed decisions but nothing, no matter how small, was made to seem trivial as they were intent on delivering an unquestionable product. The job progressed sometimes at lightning pace with crews of builders coordinated daily and we hardly had a single day where someone was not in attendance. Dali would continue with a regular update by email or phone so we were always aware of progress. When problems did occur, Dali and Michal would distress those situations, find solutions quickly and sometimes you are oblivious to there even being a problem. On the few occasions they made mistakes they were not argued about but swiftly rectified ... finding someone who was honest and proud of their workmanship has been a true find. The work progressed to schedule and the end result is something we are not only thrilled about but cannot fault at all. It is a level of workmanship we have been truly delighted with. Another thing I am confident of is that if something does happen in the future Dali will respond to my call whether it be now or in a year's time. There is so much positive to be said and I would highly recommend DPS Ltd for their professionalism, reliability and workmanship so much so I have already asked them to continue on the 1st floor.

Lukasz and his team built a lower floor kitchen extension and downstairs WC for my wife and I. From start to finish, they were extremely professional and helpful. They were the perfect builders for first time renovators such as ourselves, guiding us through difficult decisions, while sticking religiously to their timescales. They began with helping us scope out the design, adding useful insight and advice. They then set to work, making our vision a reality. Their work ethic was superb, and we were ecstatic with the level of craftmanship exhibited. Like any building project, there were unforeseen costs and issues, but these were always handled very fairly and efficiently by Lukasz and his team. We are over the moon with the end product! I would (and have) recommend Lukasz to anyone looking to undertake building work.

Extensions- 30 Dec 2020
I have only got positive things to say about this project - we are extremely happy with both the end result and the overall process. This was a big project for us, involving an extension of our kitchen and conversion of our garage into an office, to transform the entire ground floor of our property. It involved taking down two external walls and three internal walls, requiring the fitting of 3 steel beams. We had underfloor heating installed throughout and a bi-fold door extending across the whole back of our property. Zurab’s team, AZ Renovation, did everything – laying foundations, building new walls, electrical wiring, plumbing, plastering, tiling, painting, kitchen fitting, the whole works. Zurab, his main builder Mikheil and his team did an exceptional job and it was a pleasure working with them. They were friendly and helpful right throughout the project, listening to our ideas and concerns and helping us make the right decisions. Their attention to detail was excellent and they did all of their work to a very high standard. We are so happy with our new kitchen/ living area and it is an amazing space for our family. We would have no hesitation in recommending Zurab and his team for large projects like house extensions (or anything else for that matter). In fact, we have booked them in to come back next year to help us remodel our garden and outdoor area!

We hired UK Vion to do a refurb of the first floor and these guys were amazing. It was so easy to work with Ihor and the team from the start, Ihor clearly communicated about the challenges and plans and the work was done as we agreed. We even agreed some additional work that came up and the price was fair. The entire team was professional and curteous, they respected our property, kept the site clean, they were always respectful with us and the neighbours. It was refreshing to work with Ihor and the team. I can't recommend them highly enough.

Richard was very easy to deal with and kept us well informed of progress throughout the build. He was very accommodating to all our requests, including taking a week off shortly after the start of the build so as to not disturb my fiancees night shifts. The final finish is great, and we're very happy with the extension. Thoroughly recommended!
