We wanted an extension built, and what we ended up with totally exceeded our expectations. We had a rough idea of what we wanted, but with lots of communication with Marc, he came up with some very good ideas, which meant we could get everything we wanted and so much more. The end result of our extension was perfect. There was so much time, effort and dedication put into this building work we have no complaints at all.

Absolute Top service from these Men From start to finish at very competitive rates. Very polite and hardworking people that turn up rain or shine, and do the job they came to do. I made a small change to how i wanted things after they had started and it wasn't a problem, they just got on with it and made it happen. We are over the moon with the outcome and would highly recommend them for all your building needs.

Used Sterling projects for my new build property replacing the standard issue patio with a larger area of Porcelain patio tiles extended out further. Straight from the outset the attention to detail & customer service was incredible, the team are brilliant. The end result even better than expected and has completely transformed what was a originally a dull area in the garden. Highly recommended!!

Fantastic service from start to finish - Marc made it very easy for us as we had been messed around by a previous builder and lost confidence to be honest. He is super reliable and delivered on everything which had been agreed! ++++++++

Sterling Projects were incredibly professional from the onset. They cleared a large front garden with big tree stumps, Fitted concrete fencing posts with wooden fence panels and laid a big block paving driveway with soak away. Anytime there was an issue such as water mains where the fence post needed to go they were able to create a solution that upheld the original vision of the project. Sterling Projects were also incredibly tidy and courteous towards the neighbors. They completed the project in a quick timeframe whilst battling a heatwave, also charged an incredibly fair price.

Sterling Projects absolutely transformed our muddy new build garden. Keeping in mind we asked for a simple, low maintenance garden that would be suitable for use all year round - they SMASHED the assignment! They were professional and respectful throughout the whole project. We couldn't be happier that we chose Sterling Projects for our garden! Thank you so much!

We had a few companies come out to quote for our driveway renovation, but Marc and John from Sterling Projects stood out straight away. They were the only ones who pointed out potential issues with some of the ideas we had, rather than just telling us what we wanted to hear. Even before we received the quote, we already knew they were the people we wanted to go with because they were so genuine, knowledgeable and easy to get along with. We were lucky enough that they could fit us in quickly after another project was delayed, and they've been brilliant from day one. The finished driveway looks even better than we imagined, or even what ChatGPT could come up with! Whenever we were undecided on colours or styles, they gave honest advice without being pushy, and we're so glad we trusted them. We ended up choosing Autumn Gold paving, which wasn't our original choice, but now we honestly can't imagine having anything else. The whole job was completed efficiently, the site was kept tidy throughout, and everyone was respectful and professional. What really impressed us was that they were happy to offer advice and ideas for other projects we're planning, without trying to sell us anything. Sterling Projects more than just driveways, so we'll definitely be getting them back for future work. We honestly couldn't recommend Marc, John and the team highly enough. Thank you so much!

We decided to have our out of date driveway updated and have the space upgraded to more accessible and family friendly space. After online contact John was efficient in providing an onsite survey, listen to our needs and offering expert advice. John showed us a glossy brochure of possible blocks and materials that could be used, gave us confidence and vision of how our tired drive could be transformed. A few days later John and Marc provided us with a very competitive quote and gave us options regarding our boundary fence. A date was agreed for John, Marc and the team to start the project. They arrived promptly each day, worked effectively, kept the site tidy, remained professional at all times and were courteous to our neighbours. The old driveway was broken up and cleared quickly and the old concrete and rubble removed on the same day. Once the blocks arrived the team worked at a rate of knots and started to lay the masterpiece. The transformation was amazing, turning the tired old space into a stylish and useable space. Marc and John have an eye for detail and ensured everything was perfect. We are so pleased with the drive and over the moon with the finish. John and Marc also installed the new composite fence to finish off the modern look. We fully RECOMMEND Sterling Projects to undertake a new driveway, landscaping or building projects you have in mind. Don’t hesitate and get in touch for a Sterling Job.

We recently had our garden completely renovated by Sterling Projects, and the results have exceeded all expectations. From the very first consultation through to the final touches, their team demonstrated exceptional skill, professionalism, and attention to detail. Their expertise was evident in every stage of the project. They took the time to understand our vision, offered thoughtful suggestions, and executed the design flawlessly. The craftsmanship is outstanding—everything from the paving and landscaping to the finer details has been completed to an incredibly high standard. What truly set Sterling Projects apart was their professionalism. The team was punctual, respectful, and kept us informed throughout the entire process. They maintained a clean and organised worksite, and nothing ever felt like too much trouble. It was clear they take real pride in their work. The quality of the finished garden speaks for itself—it’s both beautiful and built to last. We’ve already received so many compliments, and it has completely transformed how we use and enjoy our outdoor space. We wouldn’t hesitate to recommend Sterling Projects to anyone looking for a reliable, skilled, and high-quality team. A genuinely 5-star experience from start to finish.

We have just had our drive way and stairs done by Sterling Projects and we could not be happier with the results. The work has completely transformed our driveway and the space outside our house. We could not fault the work completed. Marc and John were extremely knowledgeable and talked us through every step ensuring we were happy with the work that was going ahead. The work was completed in a timely manner, the progress daily exceeded our expectations. The attention to detail is immaculate and we have had many compliments on the work already! We would recommend Sterling Projects to anyone, thank you so much!!

We wanted somewhere to put our gym equipment so we can workout, but also needed storage for garden equipment etc, which we got exactly what we wanted. I can honestly say whatever you ask for you will get so much more, and Marc is full of really good ideas. I would definitely recommend Sterling Projects.

Home Extension
FAQs

Common questions about our extension services

Do I need planning permission for a home extension in Kent?
Many single-storey rear extensions fall under permitted development and do not require planning permission, provided they meet size and boundary limits. Two-storey extensions and side extensions usually do require planning approval. We provide expert planning guidance and handle all documentation for your Kent extension project.
How long does a home extension take to build?
A typical single-storey rear extension takes 10-14 weeks from groundwork to completion. Two-storey extensions take 14-20 weeks. These timelines include foundations, structural work, roofing, electrical, plumbing, and interior finishing. We provide a detailed project timeline during the quotation stage.
What's the difference between an extension and a garden outbuilding?
An extension is attached to your house and adds integrated living space — a bigger kitchen-diner, utility room, downstairs WC, additional bedroom or home office connected to the rest of the home. A garden outbuilding is a standalone building separate from the house, typically used for a garden office, gym, annexe, studio or bar. If you need extra everyday living space, an extension is usually right; if you want a dedicated separate use, see our garden outbuildings service.
Can you include a utility room or downstairs WC in my extension?
Yes — utility rooms, boot rooms and downstairs WCs/bathrooms are some of the most popular additions to side and rear extensions. We plan the layout, plumbing and waste routing at the design stage so everything integrates cleanly with your existing home.
Do you manage all trades for the extension project?
Yes, we provide complete project management covering all trades including groundwork, structural steelwork, bricklaying, roofing, electrical, plumbing, plastering, and decorating. Having one contractor coordinate everything ensures a smoother build, consistent quality, and a single point of contact throughout.
