How long should a 3m extension take if drawings were approved in April, the conservatory was demolished, the foundation completed, and the steel structure was already on site by May.?

We hired this builder for a 2-metre rear extension and a very large garage extension and we’re really happy with the result. The project needed a pile foundation which is a bit more complicated, but they handled everything very professionally. They listened to what we wanted and kept us informed at every stage, which really helped as we were living in the house while the work was being done. The team were friendly, easy to deal with and worked to a good standard. Overall a very good experience and we would happily recommend them.

Restoration & Refurbishment- 9 Sep 2021
The original job for a bathroom renovation turned into a much bigger job. Raphael and his team ended up helping design and renovate the bathroom, bedroom, living room and hallway. The team helped us source all the materials including underfloor heating and an incredibly intricate mosaic tiled floor in the hallway. They provided practical advise about what was best for the space, what would work within our budget and what would be easy to live with. For example, the team installed underfloor heating in the living room using wood effect herringbone ceramic tiles which would help get the maximum efficiency out of the underfloor heating whilst giving us the wooden flooring look we desired. Raphael and the team were excellent throughout delivering high quality work and we were more than happy with the final results. I would highly recommend Raph and his team.

Carpets & Lino- 3 Sep 2026
Mr Singh supplied and fitted the carpet for my bedroom. The carpet was as I had ordered upon arrival...he fitted the carpet within an hour and it was a neat and tidy job. However, time keeping was a problem but rectified later. He will return to fit a Lino for me. Mr Singh is very hardworking & cares about his clients. Thank you! 🙏

Extensions- 7 Apr 2025
Quotes were provided and the job was agreed upon. The project involved a full house restructuring and extension build. However, after several stages of work, communication with Jas was lost, and his co-worker took the lead on site. Several issues arose, such as recommending smart plumbing equipment for purchase, but their plumbers were unable to install it. The tiling, skirtings, and tiles were not completed. Tiles around the columns were cracked. After Jas's team abandoned the project, another plumber had to install all the remaining items. The job was left unfinished, and we had to find alternative contractors to complete it. Significant time and money were wasted due to persistent communication problems, failure to issue invoices, and numerous other issues. Eventually, Jas and his main labourer stopped responding and disappeared, ignoring phone calls and WhatsApp messages. Be aware of these potential issues.
A2Z
Rating: 4.7 out of 5
Extension Builder in Covent Garden
Renovations for property investors, landlords and developers. Fully insured, highly communicative team for home and commercial projects. Quotes that move after work starts. Dates that slip while finance costs run. Contractors who go quiet mid-project. We set up A2Z to fix the issues that cost property investors money. We work on written commitments, not vague estimates. Before work starts, your price and completion date are agreed in writing. If we overrun, that is our problem - not your holding cost. With regional teams across the UK, we handle refurbishments, void turnarounds, and planned maintenance. One contact, fixed terms, and a property handed over ready to let or list.
