Extensions- 27 Nov 2025
We used kelvin and Brandon to complete a conversion of a carport/garage into a Wet room, bedroom, utility, kitchen resize and the construction of a new porch. We couldn’t be happier with the work carried out by them. They handled the whole job professionally, tidily and completed almost everything themselves from groundwork’s right up to carpentry, electrics, plumbing etc with high attention to detail. Kelvin was very good at explaining everything daily and was always happy to give advice on some parts of the project we completed ourselves. We would very much recommend Hawksure developments.

Having terminated a contract with a builder for a garden room because of unsatisfactory workmanship and overrun on the completion date we needed a builder quickly. Adrian Greenmore was recommended to us by a friend . Within a day Adrian had come, assessed the work needed. We were given a clear comprehensive quotation and a draft contract. Work started and finished within the contract period. Sub-contract work was arranged and available for use more quickly than was expected. Adrian and his employees worked hard and efficiently. Some detailed work was done to a very high standard. It was always a pleasure to have them on site being polite and considerate. There were a couple of occasions when they were needed elsewhere. We were always told in advance and when they would be back ; usual no more than one or two days. Therefore we were never left wondering about 'disappearing builders'. When finished the work was passed by our architect and planning officer who was very pleased with the way the new-build jelled with the house and environment. The final invoice was as expected with no hidden costs. It was detailed and clear making everything much easier to understand. Both my wife and I would have no hesitation in recommending Adrian Greenmore to potential customers. We feel that we were given quality and, above all, a lack of hassle and frustration. We would be willing to allow inspection of the building with, of course appropriate warning.

What to ask a Norwich extension builder before hiring?

Before hiring an extension builder in Norwich or extension building company in Norwich, ask a few key questions to make sure you’re choosing the right professional for your home extension project.

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

An extension builder in Norwich 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 Norwich 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 Norwich?

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 Norwich 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 Norwich 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.
