We don't build temporary structures. We deliver habitable, brick-and-block extensions and studios built to housing standards—fully insulated and engineered for longevity.
Your garden shouldn't be an afterthought. We design cohesive outdoor living spaces—patios, decking, and lighting—that flow seamlessly from your new interior.
The engineering you don't see matters most. We install SuDS-compliant drainage and deep soakaways to future-proof your property against London’s heavy clay soil.
"Dragos did a fantastic job on my garden project, and I couldn't be happier with the results. From start to finish, his communication was excellent — always clear, timely, and professional. The quality of his work is outstanding, with great attention to detail that really shows in the finished project."
"I hired JD in the summer for a couple of jobs, including installing new garden fences and renovating part of the children's bedroom. Dragos was extremely professional and friendly to work with. Costs were fair, and the job was done in the timelines agreed and with high quality standards."
"Dragos (of JD Smart Building Services) did a great job on a new garden fence installation for me. He's a good guy, extremely hardworking and knows his stuff. Highly recommended!"

Our team handles everything from the first spade in the ground to the final coat of paint.
We started JD Smart Building because we saw a gap in the market. Too many homeowners were dealing with one company for the "ugly" drainage work and another for the beautiful finishing touches. The result? Disjointed projects, finger-pointing, and outdoor spaces that didn't quite work.
Our small, experienced team handles everything—from the foundations to the final planting. We're not just building gardens; we're engineering resilient, beautiful spaces designed for London living.
Based in Bromley, we serve homeowners across South London, West London, Kent and Surrey — including:
Plus Sidcup, Catford, Streatham, Tooting, Purley, New Malden, Twickenham and more — contact us to confirm.
