My colleague referred me to Raed who previously have had used R.Hamandi Ltd for construction work and they were very happy with the quality of service. Along with some other building company's last year I also contacted Raed for an estimate. Raed gave us a reasonable price with all the details of proposed work. He also explained about the possible options of how we could get the best value for our money. His professional and friendly advice helped us a lot to understand what exactly we needed and what was best for us to go ahead for our project. We decided to go ahead with R.Hamandi ltd. Raed gave us breakdown of the project and everything was documented. His support in communicating with council and planning related issues was valuable. All the planning permission requirements were followed. Presence of experienced and trust worthy staff including laborers, handymen, carpenters and painters really made it easy for me and family to be around and comfortable while they were working or to leave the house whenever we had to. Raed himself used to visit the site everyday to oversee the progress and used to discuss and take care of any possible issues. Raed's team used to turn up on time and the project was finished on time too. Even after the completion of the project staff at R.Hamandi ltd and Raed himself contacted us few times to find out if we're happy with the work carried out or if we needed any further assistance. Now we have a fully refurbed house with double side extension and loft conversion. Overall amazing service, professional, reliable and trustworthy. I recommend R.Hamandi ltd to everyone for an A+ service. Thanks,

I recently hired Vithesh for a loft conversion, and I couldn't be happier with the results! He completed the project with exceptional quality and efficiency. The structural floor beams and steel structure were flawlessly installed, and the roof comes with a reassuring 10-year warranty. What impressed me the most was his ability to complete the structural job in just 3 weeks, even though the original estimate was 5 weeks. His commitment to meeting deadlines and delivering high-quality work is truly commendable. I’m absolutely thrilled with the outcome and will definitely be calling him for any future projects in my home. Thank you, Vithesh, for a job well done!

Bricklaying- 25 May 2022
Top notch builders! We used Future Home Construction to build our large wrapround extension. They are a reliable family-owned company who showed up on time, worked hard, sometimes working 6 days a week including Bank Holidays. The team worked with great care and professionalism and were very informative, walking me through the process and offering me solutions to problems. We have been very impressed with the high standard of work carried out on our house and are delighted with the result. We would recommend Future Home Construction to anyone considering having work done to their house.

Ceca Developments have done an outstanding work on our side and rear extension project, and we would definitely recommend this company. Firstly, they have offered a really competitive quote for the work and have been very transparent and detailed in regards to how long it will take to complete the project. Sebastjan has been a pleasure to deal with and was very helpful during the project, providing honest and useful recommendations and being available every time we needed anything. All the work has been completed to a very high standard and to the agreed timelines. We did not have to worry about anything during the whole project, which made this a very pleasant experience.

Extensions- 4 Jan 2026
I hired Amrit based on positive reviews, but my experience was extremely poor. The work showed all the signs of a cowboy builder. I’m sharing this to help others avoid the stress, delays, and financial risk I went through. 1: No Respect for Contract or Deadlines Contract deadline was 15th September, which he completely missed. Despite delays, he demanded money almost daily. When I referred him to the payment and work schedule he signed, his response was: “I didn’t read it, I just signed it.” 2: Dangerous and Unprofessional Working Practices Brought in unqualified workers, many of whom could not speak basic English. He ignored safety standards throughout the project and wanted to use the same unqualified workers for gas work, which is extremely dangerous. When I objected, his response was: “Don’t worry, you will get a new house if it blows up as you have insurance.” 3: Work failed multiple building control inspections. He eventually refused to cooperate with the building inspector.
