Extension Builder in The City
I charge 60£ for a home visit and quote. This is to cover for my time and the website fee attributed to each add. If the jobs goes trough, this cost will be included in the final price. Hi, I am Flo, your local handyman with a decade plus of experience. Putting up a frame or building up an house extension, I can accommodate both and everything in between. If you have a project in mind i have a decade plus of experience that could come in handy so let’s get in touch. Yours sincerely, Florentin.

Conversions - General- 9 Aug 2026
Florentin created a new entrance to our house by cutting through an existing brick wall, creating two pillars and laying a path with paving bricks to connect the entrance to an existing path. He did an excellent job, working carefully, professionally and cleanly. Although not specialising specifically in heavy brick work, he clearly knew what he was doing, had the right machinery and had the skills necessary to do the job. Florentin is also courteous and well spoken. I am pleased to recommend him without hesitation.

Extensions- 15 Jun 2024
My advice is avoid. Poor communication Poor workmanship Poor quality finish Create 'issues' during build to make you pay more than quoted Left project incomplete We pursued through the Court and won the case, but of course he is unable to pay, so we are pursing further through the Court. He will respond to the review with some excuse, but there is absoultley no excuse for poor workmanship and quality. Happy to share pictures and videos on request.

Haxhi and his team exceed my expectations. We did agree on a bathroom renovation which basically everything was done from scratch. He was always on time and he met the deadline of the project. I had an issue with my water pump but he managed to fix it for little cost. Also he did the tiles for me on the wall and floor with very minimum waste and he did a brilliant job. We changed the position of the basin in order to save space and we did replace it the washing machine(hidden). We are now working on my other property to renovate the bathroom. Hahxi is very professional, knows the job very well, he did coordinate with me on every step to make sure we are on the same page . I strongly recommend him for any renovation project you may have.

What to ask a The City extension builder before hiring?

What qualifications and experience do you have as an extension builder in The City?

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?

Your The City extension builder should ensure the project complies with Building Regulations and, where necessary, handle or assist with planning permissions. Ask how they manage building control inspections and what documentation you’ll receive once the project is complete.

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

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the The City extension builder’s ability to deliver a result that meets your expectations.

How long will the extension take to complete?

Extension project timelines can vary depending on size, complexity, and weather. A typical single-storey extension might take around 8 - 12 weeks. Request a detailed schedule so you know what to expect and when key milestones will be reached.

Do you offer a guarantee for your work? Most The City extension builders offer a guarantee or warranty on their work, often between 1 and 10 years depending on the project and materials used. This gives you assurance that any issues will be resolved after completion.
