Granny Annex built by JB Construction

Home extension specialists in Rugby and Warwickshire

More space at home, without the stress of moving

We design and build home extensions that feel like a natural part of your property. From early planning through to the finished build, we manage the whole process so you can enjoy the result without unnecessary disruption.

Why homeowners choose to extend

Moving home is expensive, time-consuming and often avoidable. A well-planned extension can give you the space you need while keeping you in the location you already enjoy.

We help homeowners create additional living space that works for how they actually live, whether that means a larger kitchen, open plan living, extra bedrooms or a better connection to the garden.

We also create garden rooms and standalone buildings such as cabins, home gyms, garden bars and flexible extra living spaces, giving homeowners more ways to enjoy and use their property. Our role is to guide you through what is possible and deliver it properly.

We regularly build extensions across Rugby, Hillmorton, Long Lawford, Cawston, Dunchurch and the wider Warwickshire area, working with a wide range of property styles from Victorian homes to more modern houses.

A complete design and build service

We offer a full design and build approach, which means you are not left coordinating multiple trades or chasing different contractors. We take responsibility for the project from the early stages through to completion.

This includes support with layout ideas, structural work, foundations, brickwork, roofing, windows, plastering and all associated trades such as plumbing and electrics. Managing everything under one roof helps keep the build organised and reduces delays and misunderstandings.

Our aim is always the same. Clear communication, steady progress and a finished extension that blends seamlessly with the rest of your home.

Extensions that feel part of the home

A successful extension should not feel like an add-on. We focus on proportions, materials and internal flow so the new space feels settled and considered from the moment it is finished.

Many of our projects involve opening up existing layouts, removing internal walls and introducing natural light through rooflights or large openings. These changes can transform how a home feels and functions on a day-to-day basis.

We take time to understand how you want to use the space, then build it in a way that supports that vision.

What it is like to work with us

We know that having building work done can feel daunting. Our job is to make the process feel manageable and well-explained from the outset.

You will know who is carrying out the work, what is happening next, and how the build is progressing. We keep sites tidy, work considerately, and treat your home with care throughout the project.

Because we are a local, family-run business, our reputation matters. Much of our work comes from recommendations, and we approach every extension with that in mind.

A straightforward, reliable way to build

People choose us because they want experienced builders who communicate clearly and take responsibility for the whole job. We are fully insured, we work to high standards, and we take pride in leaving sites clean and tidy.

We keep things simple. You get honest advice, realistic expectations, and workmanship we are happy to stand behind.

Cannot recommend Jim and his team more! They built the most beautiful conservatory for my elderly parents and their patience, attention to detail, fantastic customer service and integrity was second to none!

They not only brightened up the day for my parents when working on the build but suggested some really bespoke garden alterations to help assist with my mothers mobility. Overall, they were understanding, patient, empathetic and trustworthy! This means more to me than anything!

We had Jim do our kitchen renovation/extension. The kitchen needed a lot doing, but from start to finish we were in safe hands. We had just had a baby so our mind wasn’t completely on the work. But Jim made sure we had nothing to worry about and was very patient with decisions we had to make. The team were very friendly, they also tidied up before they left. They also turned up when they were supposed to and did full days to get the job done. I would highly recommend them to anyone.

Jim and his team cheerfully worked through awful weather, managing to smile through it all. Jim worked tirelessly through difficult times to ensure our little orangery was habitable before we all went into lockdown. He was great at discussing options with us and we have ended up with a room that’s better than we imagined.

They introduced us to electricians, heating engineer, plasterer and from there to kitchen fitter. Had they not done this we would have waited months for these services. They are extremely busy but didn’t hesitate to give us help when we asked for it. Wouldn’t hesitate to give the five stars

Jim and his team cheerfully worked through awful weather, managing to smile through it all. Jim worked tirelessly through difficult times to ensure our little orangery was habitable before we all went into lockdown. He was great at discussing options with us and we have ended up with a room that’s better than we imagined.

Great work carried out by Jim. We’re very happy with the wall he built for us. He turned up when he said he would and it blends it with the other houses. It looks great, but above all, he’s a really nice friendly bloke. Would recommend.

Jim and Tyler were brilliant. Not only did they do the work they were asked to do but went the extra mile for us. They introduced us to electricians, heating engineer, plasterer and from there to kitchen fitter. Had they not done this we would have waited months for these services. They are extremely busy but didn’t hesitate to give us help when we asked for it. Wouldn’t hesitate to give the five stars

We chose JB construction to do our single story rear extension, Jim and Tyler were excellent. They were professional and the workmanship was 1st class. Jim always kept us up to date on what they were doing and what was next, always going the extra mile.

Work progressed quickly and efficiently, with other trademens that Jim used to provide the electrics, plumbing and plastering. All of which were professional and high quality work. I would have no hesitation in recommending JB construction, Jim and Tyler were always a pleasure to work with.

Cannot recommend Jim and his team more! They built the most beautiful conservatory for my elderly parents and their patience, attention to detail, fantastic customer service and integrity was second to none!

They not only brightened up the day for my parents when working on the build but suggested some really bespoke garden alterations to help assist with my mothers mobility. Overall, they were understanding, patient, empathetic and trustworthy! This means more to me than anything!

Jim and his team are professional, efficient, and extremely hardworking, ensuring the project was completed on time and to a high standard. They are genuinely nice guys to have around, reducing the level of stress expected from building work and leaving the site tidy at the end of each day.We couldn't have asked for anything more!

Jim is a completely reliable builder. His communication is first class and his pricing very competitive. Our single storey extension evolved through the process and Jim's willingness to adapt was brilliant and his attention to detail excellent. Jim is very well connected in the local building network and called upon trusted trades without any delays in the process whatsoever.

Thank you to Jim and his team for an excellent job. I would have no hesitation in recommending JB Construction.

Reliable, turned up every day, on time. Kept the site tidy. Kept us informed at all stages. Workmanship, first class. Cheerful, with a good sense of humour. We would recommend Jim for the quality of his work. We will be using him again. Twice more we have used Jim, and will use him again, all the above comments still stand, He built us an extension, laid a raised patio, replaced an old concrete path with block paving, whilst laying a new soil pipe for a downstairs loo. He'll be back for the next phase!

Jim looked after us from start to finish of knocking a structural internal wall down and putting a large steel in. The project was completed quickly and brilliantly all the way through to being plastered. He also sorted all the building inspector side out and it was an absolute dream. I would happily use him in the future for any building work and after a chat it turns out he did an extension for my parents when I was a young lad. Communication and service bang on 👌

We had Jim do our kitchen renovation/extension. The kitchen needed a lot doing, but from start to finish we were in safe hands. We had just had a baby so our mind wasn’t completely on the work. But Jim made sure we had nothing to worry about and was very patient with decisions we had to make. The team were very friendly, they also tidied up before they left. They also turned up when they were supposed to and did full days to get the job done. I would highly recommend them to anyone.

We used Jim to do some remedial brickwork to a garage. The work was completed to a high standard while we were away but Jim kept us fully informed of daily progress and offered solutions whenever needed. We found Jim to be honest, reliable and fair. We would definitely recommend Jim to friends and family in the Rugby area for any building work required.
