Since 2008




Our architects actively look to work across the range of residential projects and enjoy the exchange of ideas between. From extensions, to major refurbishment and new houses, our architects provide creative solutions working within the parameters of the site, brief and budget.


Specialise in all kinds of refurbishments (both interior and exterior) such as loft conversions, house extensions, cellars, bathrooms, kitchens, carpentry, plumbing, electrics, demolition, plastering, tiling, and painting to an exceptional standard.


A home extension is a fantastic way to add value to your property and increase your living space without having to move house. At Robert’s 21st Century Design LTD we’re experts at providing a complete home extension service.


Loft conversions offer a cost effective way to make the most of the space available in your home and can add considerable value to your property. Converting your loft space can, however, be a complex project with many factors to take into account.


Tiles and paving are a great way to create a durable, waterproof surface both indoors and out in kitchens, bathrooms, utility rooms or on driveways or patios. Tiling can be a tricky and time-consuming job to get right, which is why many people choose to call in the experts.


Creating a decked area and/or pergola can extend your living space into the garden during the summer months, and provide a place for storage and plants during the winter.


Creating the perfect bathroom for your home requires a degree of planning, design and technical knowledge, we keep this in mind whenever we start a new bathroom project whether its a simple installation or a full blown design and installation service.


Wood is one of the most versatile of building and home refurbishment materials. It is sustainable, attractive and light in weight, and can have a range of different colours and finishes.


One of the quickest and most cost-effective ways to refurbish your home is by painting or wallpapering your walls and repainting interior wood work.


Lighting is very essential for any property so you want to ensure what you have bought for your property is fitted correctly. That why choose Robert’s 21st Century Design to ensure the quality of service.


Robert’s 21st Century Design LTD has an expert team of plumbers and gas fitters ready to provide everything from servicing to complete central heating systems.


Your kitchen is the heart of your home, and we know how important it is to our customers to have a kitchen that is both practical and beautiful.



Our staff includes 50 permanent employees, 10 teams of verified subcontractors and a complete design team: a range of architects, structural engineers and interior designers providing the right mix for any type of project.

Our Reviews
Our mission is to deliver quality services, but also remarkable experiences, and outstanding results for our clients. Here are some of the clients we are proud to work with.

James Blunt

“Robert's 21st Century Design was recommended to me by a close friend. His quote was extremely reasonable compared to others, and his team’s work was quick. Together, we’ve renovated and restored a 170 year-old Chelsea pub to its former glories, and I’m really happy with the work. Robert himself was always open and positive to new ideas, and always looking to help minimise the costs. I’ve recently bought a new property, and have asked him to be the contractor on that job too.”

We are now loving our reworked house!”

Robert’s team was extremely professional , hardworking and arrived everyday on time or even earlier. We will hire Robert again in the future. ”

Nathalie Thornton

“We did a loft conversion. Robert and his team are very efficient, well organised, pleasant to work with and very trustworthy. From start to finish they had a ‘can do’ attitude. A really great team who pay attention to detail, are very neat and tidy and work very hard. They just get the job done with no issues. They also were extremely careful with keeping the site safe as we have 3 young children. Robert is excellent at communicating with what is going on in the project and always had a soloution to any issue. They come highly recommended from us!”
