Loft conversion resulting in a large en-suite bedroom

We chose Charles Grosvenor after looking at properties in the area with recent loft conversions and asking the homeowners about their experience. The feedback regarding Charles Grosvenor was excellent, in particular their after-care. Russell was our project manager and the communication was good throughout. The builders were amiable and professional and there was surprisingly little disruption throughout the build. I was impressed by the quality of work and felt fully informed at all times. On completion of the build the snaggings list ensured that any areas that I felt needed attention were addressed promptly and I felt that the overall experience with Charles Grosvenor was excellent. I recommend them to anyone considering a loft conversion.

Charles Grosvenor undertook the work of converting the loftspace of our bungalow into a two bedroom+bathroom space. Additionally, CG were contracted to remove some ground-floor walls, relocate kitchen services, fit new French door & re-plaster downstairs walls and ceiling. Windows, doors and Velux's used are all high quality double glazed units, which seal very well. We commissioned several upgrades to the 'standard' package, (such as PVT soffits and superb hardwood staircase) which we feel really finish the package. The insulation chosen for the new ceiling was the low-profile foil/plastic/foil layered type, which massively improved the head-height (one of our real concerns!) There was a bit of a delay in kicking off the job, which we understood was due to work pressure, however once it was kicked off, the process was smooth and we were involved in any decisions. Head office kept us well up to date of how we were tracking to completion, and we had regular site visits and consults from Russell our project manager. We were really amazed at the speed at which the new roof structure came together. The site crew (Billy and Rob) always acted professionally and safely, with high regard for quality. CG also provided electricians, plumbers, plasterers, and general handymen, and we can only praise them very highly. Overall, We are really happy with our new loft conversion, and would not hesitate to recommend CG.

Charles Grosvenor did a loft conversion on my 12-year-old house. It took a 3-bed semi and transformed it to give me two extra bedrooms and a shower room. From the first contact I had, I experienced nothing but professional and helpful people. The quoting process was what I’d been crying out for- a rapid and straightforward understanding of the job, the costs and the milestones. I had total confidence in them from the beginning. The work itself was like wizardry- transforming my house with minimum disruption and maximum impact. They put in steel beams, new floor joists, six new windows, boarded, insulated, put up walls and gave me new stairs in four days! The plumbing, electrics, plastering etc were all delivered well within the six weeks timeframe I was quoted. I was communicated with throughout; with next steps always made clear and I felt like my project mattered to them as much as it did to me. My loft conversion was on time and on budget, all delivered with excellent customer care. I knew who to speak to if I wanted to tweak something or get the little snags sorted. I am absolutely over the moon with the new floor I now have- it has transformed my home and I can’t fault Charles Grosvenor for their staff, service and the result. I throughly recommend this company- on all fronts!

Charles Grosvenor completed the loft conversion for us, providing with an additional bedroom with en suite shower in our home in Langley, Berkshire. We were concerned because we were lowering the ceilings on the first floor, but we were super surprised with every aspect of the work from planning, advice, support through to the actual build /completion was exceptional. Every member of the Charles Grosvenor team excelled at their job. The fitters have created a wonderful space in our loft, the plasterers have done an amazing finish, everyone were very professional in their area of work. The whole team was brilliant, patient, respectful and incredibly efficient. The office staff were polite, excellent, made us stress free with regular communication and very professional. Finally, Russell as the project manager very best in bringing it all together gem of a person. Professional, reliable , efficient, timely and great value from start to finish. Never will hesitate to recommend Charles Grosvenor to anyone without any doubt. Many thanks to you all.

I had a loft conversion into a small storage room in a small terraced house. I was very happy with Charles Grosvenor. Everyone in their team was very reliable. Hayley back at the office was very easy to contact by Email and constantly kept me posted on what was going on. I had been delaying this loft conversion because I have a busy job and don't have time to juggle building projects. I shouldn't have waited, as Charles Grosvenor made everything hassle-free!
