Carpentry- 19 Sep 2015
Not only was Ian's quote to do the loft conversion very reasonable, he was very reliable, tidy & very helpful when we had a difficult situation. The work was done in a quick time, when he said he was going to be on site he was, at no time did he let me down. The standard of work was excellent, I would recommend Ian & wouldn't hesitate to use him in the future.

Kitchen Fitting- 20 Jun 2019
Really pleased with Slawek and his team and would defiantly recommend them after seeing a professional kitchen fit job which they did for me. They went extra mile to resolve some design issues during the fit, kept the work area clean and tidy and behaved in friendly, polite manner. Nice, reliable team charging very reasonable prices.

Extensions- 24 Aug 2020
The end result was OK however there were numerous trust issues along the way which left a very bitter taste. For example we had rubble from another job they were working on, dumped outside our home and they denied knowing where it came from. Also they built over a sewer pipe without blocking it at all, which allowed rats to enter our property - they then blocked the hole with a black bin liner that the rats obviously gnawed through - then we were told the rats came in because of our standard of cleanliness! This would be a negative review however the end result was ok - it did come with a hell of a lot of stress though.

Very professional quotation, I chose over two others because he was very clear on where extra costs may arise and was very straightforward. He advised a different finish than I originally thought I wanted with cut stone edges and it looks even better with his suggestions. His crew were very friendly and professional. Would definitely work with him again in the future.

Extensions- 11 Jul 2024
I recently had the pleasure of working with Pajtim on a large project, and I couldn't be happier with the results. Pajtim is incredibly friendly, level-headed, and trustworthy. He kept to the agreed quote and consistently updated me on the progress. He understood my difficulty with planning and financial challenges and showed great attention to detail throughout the project. Although there was a long snag list, it was understandable given the project's size. The garden is still to be completed, but I'm glad I chose him. I highly recommend Pajtim for any building work.

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.

Started very good and came cross professional. But did not finish the job despite receiving half of the money in advance demanding cash payment, he left the job incomplete because demanding money in advance and threaten to leave if we don’t pay them in advance despite the job is not done according to their own given schedule. I also found out they are doing few projects at the same time that’s why couldn’t complete on time.

Restoration & Refurbishment- 25 Feb 2020
Malcolm and his team did great work on my house. The job consisted of full house redecoration, building bespoke shelving and built in wardrobes, loft boarding and installing ladder, replacing fencing and general pruning in the garden. They were able to turn their hands to all manner of jobs. Malcolm had a full team onsite every day and they finished the work ahead of schedule. At all times Malcolm was very responsive and worked hard to ensure that any changes along the way were accommodated. I would happily recommend Spring Construction and would not hesitate to use them again in the future.
