Loft Conversion- 18 Feb 2024
I wanted to express my gratitude for the exceptional work done by Cool Dudes Construction on my loft and bungalow conversion project. Despite an initial estimate of 12 wks, it was completed to a high standard within 15 wks, with only a minimal 3-wk delay due to 3rd parties (window suppliers) and the holiday season. A complex project. Full rebuild of bungalow, which included hip to gable conversion, rear loft dormer, stair, ground floor extension and full ground floor rennovations (1st & 2nd fix). Mandeep and Balwinder tackled a complex design that involved the integration of steel beams and pillars. They coordinated with various suppliers and also helped me to order skylights, windows, and doors, ensuring timely delivery and installation to keep the project on track. Team always showed professionalism, ensuring that they were always punctual, tidy, and respectful. Commitment to completing the project on time was evident, they maintained open communication throughout. One +ve aspect was their willingness to work with a private building control company that i hired, which ensured compliance with regulations. Another +ve aspect of working with them was clear payment milestones in the agreement. Payment was made on completion of milestones, which provided transparency and reassurance throughout the project. Extremely satisfied with the build and would not hesitate to recommend Cool Dudes Construction to others seeking reliable and efficient building services.

We recently had our 3-bedroom house renovated, along with a new rear extension build and a garage conversion, and I couldn't be happier with the results. The team demonstrated exceptional craftsmanship and attention to detail throughout the project. From the initial consultation to the final handover, they were professional, reliable, and transparent about costs and timelines. The renovation completely transformed our home, enhancing both its functionality and aesthetics. The rear extension seamlessly integrates with the existing structure, creating a spacious and light-filled living area, while the garage conversion provides a versatile space we can now use as an office. The team was approachable, accommodating any changes we requested during the build, and always left the site clean and organized at the end of each day. I was particularly impressed with their ability to stay on schedule despite some challenging weather conditions. If you're looking for a dependable team that delivers quality work, I highly recommend Blueprint.

Loft Conversion- 16 Mar 2014
Alex undertook several roof repairs as result of storm damage. This also required making good of interior damage as well. As a result of his good work doing this job I gave him job of redecorating an entire room, this including installing coving. Overall Alex and his team did an excellent job, any issues I had were dealt with and they went above other builders in terms of the care they took to my house when doing the work. I am already looking to give Alex further larger jobs in the next few months and will happily recommend to friends and family. Ravi Mill Hill, NW7

Extensions- 10 Jun 2020
We had a one bedroom lower ground floor garden flat and did a side return and extension into the garden. The flat is in West Kensington area. We also did a full internal refurbishment and moved just about every wall, moved boiler, new Porcellanosa bathroom, new kitchen, new flooring throughout, a large bi-fold door in the living room to the garden. Chris and RAS Construction have been the best possible builders for this project. They were simply amazing. What we loved most about them: - speedy and no-nonsense communication (very important for us) - friendly and approachable - super professional and friendly team - very quick and helpful when a problem arose due to some architect's error - good aftercare - stayed in quoted budget - offered improvements and reasonable quotes - very easy to work with - only asked for partial payment every few weeks after job had moved along reflecting the amount charged This review was written about 8 months after the project was completed and we are still very happy with the quality. I would not hesitate to recommend Chris and his team at anytime. You hear so much about bad builders, we have been very lucky that we have found him. We are now house hunting for a bigger place and will re-engage with them for the next project.

Plumbing- 24 Sep 2018
Had confirmed I would take a day off for the job. Received a text on the day at the time he was meant to come saying van had broken down and could not come. Then offered to send a friend to do the job. Waste of a day and spent morning running around buying the equipment. If the van did really break down then that’s a fair excuse. Negative experience from my end.

Loft Conversion- 27 Sep 2020
I met Jay for the first time on mybuilder.com; my job, roof extension received a huge interest; Jay was one of the first that came to discuss and he had one of the best quotes; although we discovered in the last second that the structural calculations were different from what actually the structure is, he was not afraid to get involved, and we worked along the engineer all the way through; his attitude and his team attitude was professional from day 1 until the end; the team came every day at the same hour and they were working really hard; in fact after just 1 day, the old roof was off, new structure was on with a rain proof cover; this thing told me from day 1 how professional and hard working they are and confirmed me that he was the right choice; the extension was done in half time just as a confirmation of above; they accommodated all my requests (like fitting air con pipes); the end result was great, or even better than expected; I truly recommend him and would certainly work with him in future projects.

Joinery & Cabinet Making- 16 Dec 2016
Benny did a great job boxing in pipes and electrical wiring in both the kitchen and utility room. In particular he framed the consumer unit in the kitchen with a single piece of laminated mdf whilst concealing all the pipes and wires in the vicinity. Some of the angles were quite tricky, but still the mdf was cut to 100% accuracy. In the utility room where he used unlaminated mdf, the finish of his work was done to a very high standard with all the end grain of the mbf filled with two pack filler, and sandpapered ready for painting. The pipes were somewhat irregular, but the final look, with new architraves, minimises the impact of the boxing in. I will engage Benny next time I require carpentry to be done to a high standard.

RS Building successfully delivered two full back-to-brick refurbishments and a new-build development for us in Greenwich, including demolition and construction of four new dwellings. Their level of workmanship is exceptional, and their attention to detail is second to none. As experienced property developers, we’ve worked with many contractors—but RS Building stand out for their reliability, quality, and professionalism. We have since recommended them to several colleagues, all of whom have been equally impressed. Our only regret is not finding them sooner. We look forward to working with them again on future projects.
