Conversions - General- 27 Jun 2025
Majed and his team were outstanding from start to finish. We had our entire first floor renovated—four bedrooms and a bathroom—each room with a unique design: a master bedroom, a nursery, a kids' room, and a study/home office. Our design requirements were detailed and quite strict, from precise placement of mouldings to ensure symmetry, to fitting LED strips seamlessly within custom wood panelling. Majed took the time to understand exactly what we wanted and delivered with precision and care. The whole team was professional, polite, and incredibly respectful—especially important as we were living in the house throughout the renovation. They worked around our schedules and limitations without issue, and always kept the space tidy and disruption to a minimum. Special thanks to the joiner and the decorator for their excellent workmanship and attention to detail. We’re genuinely thrilled with the outcome and would highly recommend Majed and his team.

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!

Mario was an absolute gem from start to finish. After a leak left our only bathroom out of action Mario came in and managed the full project to perfection (and also had a great tiler and electrician who did some other works). Six months on and I cannot fault any of the works. Highly recommended.

Emanuel responded very promptly and visited on time. His response to the job was positive and he came up with some helpful ideas. His quote was reasonable and detailed and he came up with a date for the work which was completed as near as possible to the exact time given allowing for unseen hitches. We have been very pleased and would recommend him without hesitation. A job really well done.

Pawel worked on my son's property in Notting Hill, London. The final result was absolutely wonderful. I found Pawel incredibly helpful, skilful and willing to change things last minute, as I procrastinated over every job! He left the property clean and tidy each day, and the end result was a flat that has been transformed and improved beyond recognition. I would thoroughly recommend Pawel and will definitely use him again in the future.

Dan and Freddy are a powerhouse team, although we are yet to start the construction of our project they have worked tirelessly to assist us in getting the perfect design and plan in place. All investigative work has been incredibly efficient, every single person we have dealt with has been highly skilled and been great at communication. We’re super excited to get started and can’t thank them enough for all their hard work up to this point. We couldn’t recommend them enough for design management and everything leading up to construction (including dealing with tricky neighbours) and am sure I will be back to write as glowing review when construction is complete. Thank you Dan particularly for going above and beyond… it’s been rather pain free and that’s all down to you.

I am really happy with Gerry and his teams work. My son's room feels all brand new. Gerry was reliable, on time, and kept all dust and dirt under control. They finished the chimney breast and stack removal and plastered the room all in the said time which was a relief as its always a worry that things will drag on. Gerry even arranged to have it painted. I very much recommend these guys and have now booked them in to remove and replace my front garden wall.

Excellent. Reliable. Honest. Hardworking. I don't typically respond or leave feedback though in this case, Slav and his team thoroughly deserve it. They helped pick up the pieces from the mess left behind by a prior builder and worked hard to turn it around into a success story. I would have no hesitation whatsoever in using SGB again and in recommending their work to both friends and colleagues.
