Extensions- 13 Dec 2021
Couldn't recommend Domi & Emile enough. They have great building knowledge and kept us informed and up to date throughout the whole building process. The job was finished to a high standard and they even came back free of charge to tie up a few snags a few weeks later. Great builders and a great team!

Kitchen Fitting- 18 May 2017
Cannot fault the work Tony undertook. Completed on time, finished to a very high standard, kept informed (we were away on holiday whilst work was being done). So pleased with the result, my daughter's room is what was the kitchen and looks beautiful. New kitchen fitted with new floor tiles and looks fantastic, boiler was moved etc. Can't recommend Tony enough and I will definitely use Marsdens again.

SSS BROTHER, They worked incredibly hard to transform our house in a timely and efficient manner, all whilst being responsive to our concerns and preferences. The SSS BROTHER did a great job extending our kitchen and backroom to create a beautiful space that we love hosting family and friends in. The job was completed to a high standard and with good communication. Throughout the work, the workers were calm and knowledgeable and - importantly for us - helpful and offered their opinion of how the extension should be built.

Extensions- 17 Jul 2020
Orgert Myrta and his highly skilled team did an exceptional job renovating our Victorian terrace house in under 8 weeks. On meeting Orgert, his warm, friendly and professional manner was reassuring. I immediately thought he was someone I could work with. His initial assessment of our house, he advised on best possible solutions to achieve our aims within budget. He invited me to visit the homes of his recent previous clients & obtain their feedback, which I did. Visiting two clients, they both spoke highly of Orgert & his team, sharing their positive experience and how Orgert has since completed work on their neighbours homes & family members homes too. Judging by the quality of work completed in both client's properties, I knew Orgert was the right builder for me. Responsive & prompt throughout, good communication, providing weekly status updates, even advising on where to source great deals on second fitting items saving us money. To say we are pleased with how well the project has gone & level of workmanship is an understatement! Without hesitation we highly recommend Orgert & his team, who since finishing our house are now doing work on my relatives house. Orgert & his team completed in our home: - Rewiring & new plumbing - Plastering walls & ceiling - Replace old ceilings - Painting & Decorating - Painted exterior front & back - Replaced & repointed brickwork - Installed new kitchen & bathroom - New flooring throughout

The job was a complete refurbishment of a one bed flat, including rewiring and re-plumbing. We would recommend Al and his team without any hesitation. From the very beginning and all the way to completion, we felt very lucky and fortunate to hire them. We found them to be very hardworking, conscientious and professional. The job was a difficult and complex one, but the team still completed within time and within budget. Al's advice made the whole process easier and we found him to be very trustworthy and honest. The end result was better than we originally hoped for and was done to a high standard.

An extension builder in The City should have a strong track record with similar projects and relevant building qualifications or trade memberships, such as the Federation of Master Builders (FMB) or TrustMark.

Will my home extension meet all building regulations and planning requirements?

What experience do you have with similar extensions in The City?
