High-End Room Conversions
in London

Bring luxury living to every inch of your home with our total room conversions.

Reimagine Your Home

It's easy to overlook an unused garage, loft, or basement. They're out of sight and out of mind, only stepped into for the occasional clean. Unfortunately, that means missing out on a lot of valuable floor space - floor space that could be transformed into something truly spectacular.

With a conversion, you can turn a neglected room into a fresh, modern space for anything you envision. From a dusty loft to a guest bedroom, workshop, games room, or even a home cinema… the only limit is your imagination.
At SM London Construction, we have years of experience transforming rooms of all shapes and sizes. We offer a complete structural and fit-out service and work closely with you to make your vision a reality, adapting the decor and layout to match your personal style. Ultimately, you'll be left with a gorgeous, multifunctional room that fully realises the raw potential of your home.

We’re ready to start when you are. If you'd like to take the first step, book a consultation online or give us a call on 07961 817 505 or 0208 226 5511 today.

Designed Around Your Home

No two homes are alike, which is why we take a fully bespoke approach to our designs. We customise every detail - from wall colours to structural elements - to seamlessly blend into your home's distinctive look and feel, as well as your own personal preferences.

During a complimentary in-home consultation, we'll assess your existing room, discuss your goals, and develop a custom design tailored to your needs. We'll check with you through each step of the process, making sure the final result matches exactly what you've been imagining.

With years of experience converting all kinds of rooms, we have the expertise to achieve stunning, one-of-a-kind results. Browse our gallery for a sampling of our bespoke work.

Every Step Taken Care Of

Our mission is to make the process as smooth and streamlined as possible. We offer a comprehensive start-to-finish service, handling everything from initial consultations to the final conversion, so you don't have to coordinate multiple contractors. You'll also work with the same dedicated team throughout, resulting in a seamless experience with clear communication.

Beyond building and design, we provide full support at every stage of the project. Our experts will advise on decor, fixtures, layouts, and other design elements, helping to maximise the potential of your space without exceeding your timescale or budget. We’ll also provide support post-completion of the project, if you ever have questions or want to explore further options for upgrading your home.

Client Testimonials

Discover what our previous clients had to say about their experience working with us.

SM Construction did a full loft conversion for us and it was an excellent experience. Starting from a very detailed quote which they stuck to; to fast and high quality work. The workers were knowledgable and helped us make all the small decisions. They were also very well behaved and respectful of our space which was important as we were living in the house while the work was going on. Have already recommended SM to a few people and will not hesitate to recommend them to anyone. Top quality work at a reasonable price.

Loft Conversion

We bought a house that hadn't had any work done in a while and did a full reno - 2 bathrooms, loft conversion, garage conversion, knocking through kitchen wall, installing new kitchen, repainting, new heating, new floors, painting, lights, etc the whole shebang. Everything was done on time (16 weeks). Really easy working with Shaz and his team - they were all very polite and friendly, gave useful advice and did a really good job. We're very happy with our new home.

Home Renovation & Loft Conversion

Loft conversion for a 1930s semi in Greater London. Shaz and team we're really helpful and efficient. They kept to the original agreed timeline, always communicative about options and potential changes. In particular they noticed that the original plans from our architect were going to lose us a lot of space and they clearly explained an alternative (no extra cost and has worked so much better). Slightly creaky floor but everything else is just right.
