You can stay in your favourite Northampton area and get the extra room you need.
We offer many building options to fit your home and budget. A single storey rear extension adds space to your garden for a large dining area. A double storey extension gives you a large kitchen downstairs and a new bedroom upstairs.

Bringing the Outside In With Natural Light
Modern building projects fill your home with natural sunlight. Older homes often have small windows that make kitchens feel dark. We fix this by adding clever design features to your new space.
Adding a bi fold door at the back of your home is a very popular choice. These large glass doors open fully to connect your kitchen to your garden patio. Imagine a summer party where your house and garden become one big space. We also fit roof lanterns and skylights to make every corner bright and welcoming.

We know your home is your most valuable asset. That is why we promise a high quality finish on every project.
We manage the whole build from the first drawings to the final painting.
Our expert team handles the plumbing wiring and plastering for you. We use top quality materials so your kitchen extension looks great and lasts a long time.

What our clients say?
EXCELLENT Based on 30 reviews Posted on Google Tricia DawsonTrustindex verifies that the original source of the review is Google. This was a large project and it encountered unexpected problems but Damax were excellent in addressing whatever came up and solving these problems quickly and efficiently. I am extremely pleased with my new kitchen and the additional jobs to insulate the study etc. They also did everything they could to keep problems away from me, protecting the customer as much as possible. They were clean, efficient and I was kept informed at all stages. All the different workers who came to the house were pleasant and friendly. I would have no hesitation in recommending them to friends, family and anyone else I know who is looking for a bulder.Posted on Google Andrea RichTrustindex verifies that the original source of the review is Google. We wanted an extension to our property but only upstairs. We didn’t want to project manage ourselves so after plenty of searches, decided upon Damax. From first conversation with Sam, we explained what we had in mind and he set to drawing some plans. We signed on the dotted line and got a start date. Due to Christmas, this slightly changed but that was fine. Work began on 5th January. Throughout the process, we were spoken to respectfully - sometimes tradesmen can be very condescending to laymen - not Damax staff. Whatever question we asked, was answered and explained fully. From the initial start date right through to the end, we have nothing but good comments. The rain early on in the year was relentless and they only finished early ONCE. Shout outs go to Darren but especially Nathan, Sean, Ellie, Charlie & David - masters of their craft. It looks fantastic. Thank you! Andrea, Andy, Miles & Ruby ❤️Posted on Google Heather ProrokTrustindex verifies that the original source of the review is Google. In June 2025 I asked DAMAX Building solutions for a quote to install a new kitchen. They came out promptly and assessed the job, made some clever suggestions when I wasn’t sure what I wanted and sent in a comprehensive and competitive quote very quickly. This included removing a chimney breast up through the house to the attic. From the start the team were reliable, friendly and well organised. They arrived when they said they would and always kept me up to date with what was happening and what the next steps would be with an approximate time for when this stage would be completed. They delivered outstanding workmanship and always cleaned up when they had finished for the day. All the tradesmen were polite and friendly. When I needed to speak to anyone at the office there was always someone available to answer my questions. Because I was so pleased with the work on the kitchen, I asked them to quote for a complete bathroom renovation at the end of 2025. Again, they were extremely helpful, and the work was completed to a high standard with as little disruption as possible last month. I am extremely pleased with both projects and would not hesitate to use them again and to recommend them to anyone thinking of having work done. Heather ProrokPosted on Google luke brittanTrustindex verifies that the original source of the review is Google. We hired Demax to build an extension on our property and they did an excellent job from start to finish. The work was completed to a very high standard and the whole team was friendly, professional, and genuinely helpful throughout the process. They worked within our budget and were completely transparent with information at every stage. No question ever felt like a silly question, they always took the time to explain things clearly so I understood the process and the next steps of the build. Overall, an excellent experience. I would highly recommend Demax to anyone considering building work or an extension.Posted on Google Attila BihariTrustindex verifies that the original source of the review is Google. We asked for advice to remove a wall. Sally was very kind to help us. Everything went very easily and professionally. Thank you to the company and Sally. We will contact them for future work.Posted on Google Matthew LevaiTrustindex verifies that the original source of the review is Google. Great service from Damax when dealing with our leaking toilet recently. The problem was quickly diagnosed and fixed all within 30 mins of arrival. Left the area clean and tidy and would happily recommend Damax to others for both building and plumbing services. Damax are capable of dealing with all types of home improvement and property maintenance tasks. Keep up the good work.Posted on Google Lisa PattersonTrustindex verifies that the original source of the review is Google. We reached out to Damax with concerns around a potential issue with our roof/chimney. Darren responded during his annual leave and arranged a visit. During the call I was reassured entirely and upon the visit Darren explained thoroughly how the roof and structure works. Instead of making a job from nothing, he kindly explained we did not need to worry and that work was not required. I felt it necessary to give good feedback as this showed an honest tradesman and instead of creating a job and taking money unnecessarily, he had advised us and gave us a better understanding. We offered money for his time to assess the job and again he declined. From the experience I can 100% say that we would use Damax for any future issues we may have due to the professionalism and kindness shown throughout our interactions. Thank you for reinstating our faith in there being honest and professional tradesmen out there 👍🏼Posted on Google catalin sanduTrustindex verifies that the original source of the review is Google. Daren and the team were brilliant in delivering their services. Very professional and prompt in all matters. Happy to chose them and strongly recommended!Posted on Google Phil SmithTrustindex verifies that the original source of the review is Google. Recently had our 1930s semi knocked through, from an old, tired galley kitchen into a new , modern kitchen/diner. Communication was great from the off, we knew when work was due to be done and it was carried out promptly and efficiently. We are delighted with the results and would not hesitate to use DAMAX again for further projects.Posted on Google Anitta MichaelTrustindex verifies that the original source of the review is Google. We used Damax building Solutions Ltd for renovation works in our recently purchased old Victorian house. Darren and his team( especially two Mark’s) were excellent. All works were completed as discussed with no delays or excuses. Thank you.
