considerations of a house extension.

Regardless of whether you are considering a modern kitchen extension or a more complex build with multiple storeys, any house extension requires careful planning and consideration. The complexity of a house extension should not be underestimated and must factor in everything from energy efficiency through to fire safety and structural integrity.

It’s therefore important you have an experienced construction team that not only understands the complicated legal rules, but one that also understands the practicalities of the build itself. 

As a small family run business with over 45 years of active trade, AJ Hammond Builders have become the trusted building contractors in East Sussex. We’ve built home extensions in Bexhill, Eastbourne, Hastings, Lewes, Heathfield, Tunbridge Wells and beyond.

Our experience and customer feedback has demonstrated that keeping you up to date with the construction plan makes the build process a lot more straightforward for our customers – something that often gets undervalued.

A word from our customers.

Neil Hammond’s team is the best we have worked with by a mile. From start to finish everything was carried out to the highest standards. Every night the property was left clean and tidy. Friendly, efficient co-operation throughout the exercise made it a joy rather than one we couldn’t wait to be over!

- David & Adela
Hastings, East Sussex

AJ Hammond Builders are truly a family affair with Neil and his two sons at its core. We’ve known Neil for over 20 years and have used the company a number of times for building projects we’ve had. AJ Hammond Builders are reliable, competitive and their work is always of the highest quality.

- Nigel
Little Common, Bexhill-On-Sea, East Sussex

We are delighted with the work carried out on our home by Neil and his skilled team. The project was undertaken with respectful, courteous professionalism and extreme attention to detail. Not the most competitive quote we received but this is reflected in the quality workmanship and high standard of finish needed to achieve the fantastic end result.

- Frank & Jackie
Bexhill-On-Sea, East Sussex

We’re absolutely delighted with our extension recently completed by Neil and has team. From start to finish our project was managed by Neil, who was always available for advice and there to oversee proceedings. A polite, friendly workforce, always leaving the site tidy at the end of the day. We’ve received lots of compliments from friends and neighbours since the work has been completed and wouldn’t hesitate to use AJ Hammond again and recommend to others.

- Dan & Susanne
Little Common, Bexhill-On-Sea, East Sussex

Neil and the team did an amazing job of a two storey extension on our family home. One of our biggest concerns was how disruptive the build would be having small children in the house but the whole team could not have been more respectful and we felt fully supported throughout the whole process. We have recommended them to many people locally who have been equally as delighted as we were with the end result.

- Siobhan
Little Common, Bexhill-On-Sea, East Sussex

Well managed and well executed projects. All handled in a timely and professional manner with a polite and friendly team. Additionally always provides clear quotes quickly after reviewing the jobs which stay true to the project. Not always at first sight the cheapest but always the best value due to the quality of workmanship. You always know where you stand. I would have no hesitation in recommending AJ Hammond Builders.

- David & Karen
Dallington, East Sussex

We had a 2nd storey extension and Neil was brilliant, sorted everything out to a high standard, including the other trade/contractors he brought in. It was a first-class job and I would highly recommend AJ Hammond Builders. We now have a stunning new bedroom to enjoy!

- Matt & Emma
Cooden Beach, Bexhill-On-Sea, East Sussex

Neil and his team worked relentlessly to complete our extension in time for Christmas. They were always polite, tidy and cleaned up every evening. We are looking forward to the next phase of the build in the summer. We would highly recommend them.
