Bathroom Fitting- 2 Jun 2026
Amazing work, Sam and his team are dedicated professionals that have real eye for detail. The toilet needed changing position which required a significant amount of rework of pipes. But they made it look easy.. tiling work was done perfectly and Sam helped me find the right products before starting this project. Really happy with the work done and was completed in a timely manner. Highly recommend.

Architecture- 27 Nov 2017
I contacted Marius because he had good reviews and wanted someone reliable and capable so design a single story extension with large external and internal bifold doors. I wasn’t disappointed - Marius has been excellent throughout the whole design process and produced drawings to a high standard which met our requirements. Marius was an excellent communicator and always available to give advice when required. Further more, he went out of his way to contact local authorities regarding any questions I had at no extra cost to clarify any uncertainties. I would highly recommend his architectural services - he was good value and very professional.

Bathroom Fitting- 7 Nov 2025
Amazing work done by Antonel and his colleagues! The job was done to a very high quality standard and they were very thoughtful towards my needs always keeping good communication from the start of the process. Antonel promised me a very tight deadline of 5 days and he made sure this was met, always ensuring the job was done to a very high standard, I couldn’t have asked for more. Definitely someone I would recommend to anyone.

We needed an experienced and skilled tiler, to fit 800 x 800 glass fronted tiles to a TV wall. The tiles were manufactured to size, and formed one large pattern. Arben did a fantastic job for us, he finished the job in one day, and it was completed to a excellent standard. I highly recommend him!

Stefan initially quoted for our extension however, we used them for a few other jobs instead namely summer house, now the porch at the front of the house and will be using him for our garden and driveway work. He is very professional and has completed the work with a very high standard. His team are very claim and make sure that there is no mess left at the end of the day. Great communication. Would highly recommend hence why we are using him for other work and I have recommended him to family members.

Restoration & Refurbishment- 20 Oct 2022
I contacted Korab to remove my chimney breast, he came to have a look, quoted me for the job and then started the work. Once the work was completed I was over the moon with the work that Korab and his team had done and the service they provided and I asked them to have a new full refurbished house (new electrical work, new plumbing, new plasterboards, new skimming, new doors, new laminate flooring, new tiles, new skirting boards,new bathroom), side extension (which korab helped me to design)and garden patio and a new front garden wall. Korab was a very friendly and easy-going person from the moment I met him in regards to my first project (the chimney breast). He would pay attention to every detail and always ask if I was happy with the work which was being carried out. Korab and his team would always ensure that the work space was left clean. Korab and his team were more than happy to have an input and make suggestions when I needed them too, he also make me feel comfortable to ask any question. Korab and his team did an amazing job in my house and completed the work to a high standard in which I was so happy about. They truly are an experienced group of guys and I would highly recommend them to anyone. What a pleasure it was to have met them. Thankyou once again!

Carpentry- 28 Jan 2026
Ali did an exceptional job designing and building our staircase, and I couldn’t be happier with the result. From start to finish, he was a complete gentleman — polite, respectful, and a pleasure to deal with. Ali is clearly a true specialist at what he does. His knowledge, attention to detail, and confidence in his craft really stood out. He was able to design and install the entire staircase in just one day, which was genuinely impressive given the quality of the finish. He worked efficiently, kept the area tidy, and took great pride in his work. It’s rare to find someone who combines skill, professionalism, and good nature so well. I would highly recommend Ali to anyone looking for a high-quality staircase installed by a true expert.
