Bricklaying- 9 Dec 2025
We agreed a start date for the work, and from the beginning communication was slow and required constant chasing. Alan sent me a full materials list, which I purchased on the understanding that the job was proceeding. As the start date approached, I repeatedly tried to confirm when he would arrive so I could organise my day and be available to help on site, as we agreed for me to b involved as a labour. Despite reading my messages, he stopped responding entirely. I sent multiple messages and tried calling several times over the course of a week and received no reply at all. The job never started, and I was left with purchased materials and a significant amount of wasted time. I cannot comment on the quality of his work as he never turned up, but based on the communication alone I would strongly advise others to be cautious.
I-build construction (south) LTD
Rating: 5 out of 5
Extension Builder in Brighton
Hi, My name is Ian, I own and run i-build construction. I have 28 years experience in carpentry and construction. I have a small permanent team, and reliable subcontractors that work closely together to bring calmness and quality to your project from conception to completion. We specialise in domestic extensions and new build homes. We can take on smaller refurbishment or carpentry works, but are just as comfortable with complex structural alterations and extensive groundworks. I personally carry a Construction Skills Certificate Scheme black card and hold an NVQ level 4 qualification for site management. I am also an associate member of R.I.C.S. This means you can relax, knowing your work will be well organised, done safely, and the site and work on it will comply with legal obligations. In recent years we have helped several self builders who wanted to have a professional team take on parts of the construction, manage building control and compliance duties, but leave them parts of the project to handle themselves. Our customers like the transparent, honest approach we adopt, and that we will stick to a project, once started, not leaving you wondering if the builder will turn up today, or ever again. Give i-build an opportunity to impress you😃

We employed Ian and his team to help us develop a large plot which included a barn conversion (which as class Q was complex as it required maintaining the original timber structure and inserting a steel structure within) and the redevelopment of the existing farm house. Over a period of 2 years Ian managed the conversion into a luxury 4 bedroom home with an outdoor kitchen area, and a sizeable extension to, and complete refurbishment of, a period farmhouse, as well as a double detached garage, an annexe outbuilding, extensive landscaping and complex drainage and ground works. This project involved co-ordinating the designers (architects plus interior designers) and several contractors. We found working with Ian and his team was stress free and the completed works to be of a consistently high standard. Everyone who saw the finished buildings was impressed with the quality of finish. It was comforting to have the job in the hands of such an honest and professional team. They were particularly respectful of our young family who lived on site throughout.

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

An extension builder in Brighton 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 Brighton 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 Brighton?

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 Brighton 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 Brighton 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.
