Extensions- 16 Nov 2019
I was very lucky to find Cornel for my building work. His team were extremely hard working, efficient and respectful and the work was done very quickly and to a high standard. Most estimates for the build time were between 8 and 10 weeks - my work was fully complete in 6 weeks. Building control passed all stages of the work without any issues. He is equally proficient at the plumbing, electrics, flooring, tiling and decorating as the heavy building work, even restoring my garden so that it looked better than it did before the build. I am in a conservation area with close neighbours on all sides and Cornel minimised the disruption as much as possible and made efforts to keep everyone happy. His attitude to overcome problems and make sure that in the end you are a happy client drives his approach to the work. I had 10 builders quote for the job and Cornels quote was very competitive and the final costs were exactly as we had agreed. I had spoken to a number of his previous clients before going ahead and they were all very impressed with his work and had good experiences. It can be a difficult decision to choose a builder if you have no previous experience and given the potential for things to go wrong - but we made the right choice. I wouldn't hesitate in recommending Cornel and his team.

I looked at 5 quotes and was so happy to have chosen Elvis and his highly experienced team. They did an excellent job of building a new 11sq meter garden rear extension. This was a bit complicated project because it’s a listed house. Elvis and his team were hardworking, always responsive and came up with great solutions when necessary. I am very pleased with the high quality end result. I would use them again and can't recommend them enough! Great job done

Painting & Decorating- 1 Jul 2017
I would highly recommend these guys. They did a very high quality job decorating my lounge, dining room, hallway and stairs. They started the job on time, worked through the weekend to get the job finished in good time, left the place clean and tidy at the end of every day, and cleaned up immaculately at the end of the job. The price was also very competitive compared with other quotes I received. I hope they are available again in a few months time when I have more decorating that needs to be done.

Victor (Vica) laid some engineered oak wood flooring for us in a house that we bought at the end of 2013. The house needed lots of work doing and the new flooring was just one of the many jobs undertaken by Victor and carried out to a very high standard for us. He always paid attention to detail, ensured that the flooring was level and that the new skirting board fitted flush to the floorboards. He was also always able to provide a solution to any problems encountered during the renovation works. I would have no hesitation in recommending Victor as he takes the same pride in his work for others as if he was carrying out work in his own home.

Extensions- 2 May 2018
Tom is a very competent builder, who has attention to details. Tom continuously went out of his way to find ways to meet my requirements, Whenever we had atypical challenge during my extension Tom's default position was "let's find a work around." He was creative and efficient in doing so, and most importantly cost effective, as I was running on tight budget. Fantastic experience working with Tom, he estimated the work to complete in 6 weeks, the work was done 5 and a half weeks and handed over. The works speaks of itself, very urban finish with high level of professionalism. I was almost hands off the project due to work travel, and Tom took care of all the aspects without me being involved day to day and micro manage. He is surely being to be big league builder in no time. I would recommend him whole heartedly.

Restoration & Refurbishment- 31 Aug 2020
It was a pleasure dealing with Peter and his team from start to finish and we couldn’t be happier with the work that they did. I was impressed with Peter’s previous work and we developed a good rapport from the first meeting and I felt that I could trust him with the work. He was clear about the detail of the work that needed doing upfront and his quote was itemised to reflect what each element would cost. The work was done on time and of a high quality and Peter was responsive at all times to any questions or concerns we had. He also made great suggestions of how we could do things better and was open to our ideas and realising our dream. His team were punctual, friendly and took care of the house ensuring the work that they did was of a high standard at all times and attention to detail which really has made a difference now that the project is completed. I wouldn’t hesitate to recommend Future shapes to anyone and would certainly use them again.

Restoration & Refurbishment- 12 Jun 2026
Hired to finish off a complete flat renovation - work mainly consisted of painting, some remedial repair work, light carpentry and a snagging list. Whilst Raj and his guy were great at light repairs, handyman and carpentry work (which is the only reason I’m even rating them with stars), their attention to detail and completion of the snagging list was very poor! Despite having discussions with me to rectify things after I showed him examples, the flat is now left with uneven paint edges, drip marks, uneven grouting, unpainted architraves and sloppy silicone work. Whilst they are good at some things, decorating is definitely not one of them, so it’s a shame and disappointing.

Carpentry- 29 Jan 2026
I contacted Ekland and his brother Bes for some light refurbishment. I was so impressed with the work and speed that they ended up doing all the works I intended to do. Starting with latex screed, flooring using LVT system, architraves and skirting boards, installation of 9x heavy duty fire doors, carpets in 2x bedrooms and finally decoration. Prices were very reasonable considering the time and effort they put into installation but not only that, as I am a first time buyer they advised me on design as I didn’t really know where to start. They are honest and reliable, where I tried to save money they said it was not the right thing to do and took additional hours to make something right without a hidden extra. They turn up at 8am everyday and so easy to work with, I left them the keys to my flat and I didn’t need to check in on them at all. If you are thinking to do any refurbishment and are either hesitant or not knowing where to start these are your guys. 5* to Vukaj and thank you!
