Openplan Design is a UK-based firm that specialises in designed interiors utilising natural stone and engineered surfaces. With high standards and integrity, we have been delivering bespoke kitchens, bathrooms, living rooms and bedrooms for both our residential and commercial customers. Our full-spectrum service encompasses all aspects of your building or renovation project from design to final installation, starting with a free consultation.
Openplan Design is a trading name for Ashlar Mason Ltd. Founded in 1995, Ashlar Mason was established primarily as an importer and processor of natural stone. We have gained valuable experience in this field over the years, keeping in step with the demands of the market and ever-changing trends. We are truly experts in all things stone, including having worked with the rarest types of onyx on the planet. It is not uncommon for us to hand pick our stone from sources around the world so that we can keep our London warehouse stocked with all sorts of interesting stone options, ready for your viewing and selection.
We constantly place ourselves ahead of manufacturing practices, embracing new technologies that help us push the limits of our capabilities. Whether it’s keeping up with advancements in man-made materials such as quartz, Dekton and porcelain, or incorporating cutting edge technologies into our London factory, we are proud to be at the leading edge of the market.
In 2002, we expanded our product range into the supply of kitchen cabinets, appliances, and bathroom fittings. This was a natural progression for us, driven largely by requests from our existing customers for more comprehensive interior design solutions. In 2008, we again extended our product offerings into bedroom and living room furniture and fittings – a decision which positioned us as a one-stop shop for turnkey services delivered by a skilled team of designers and fitters. Our 2012 foray into luxury interiors found us renewing and developing partnerships with some of the best, most experienced, reputable and inspired European manufacturers to create a luscious showroom selection for our customers.
With all of this knowledge, skill, and experience at our disposal, we are unfazed by even the most complex projects. We welcome you to the Openplan Design experience, and look forward to helping you bring your projects to life.

What a pleasure to work with a company that works with the client, offering the best products, being flexible and friendly, professional and helpful and without giving any excuse! We got our kitchen fully designed and installed by OPD, including the kitchen top and all appliances. Top-quality products, beautiful kitchen top. We are thrilled with the outcome and we would like to thank all the team members for making this to happen and above all a massive thank you to Sam who managed the entire project for us and made himself available 24/7. What a great team.
A massive thank you to both of you for the superb job done by all the staff at OPD. Quality of work was excellent and attention to details was second to none. Everything turned out better than we imagined. An excellent job by all the member of staff, in particular Hasan, who managed to solve difficult problems due to old plumbing, defective walls and floorboards without stress and with great amount of patience. He put in extra needed time – on many occasions – for the kitchen and bathroom projects with very good grace. He is excellent!
My wife and I would like to thank you, in particular for your exceptional professional supervision and great help in choosing desired/suitable granite worktop, Corian and Dekton during the projects.
Looking forward to yet another superb project through OPD!
When we moved to our new home, my wife and I decided to upgrade the kitchen and convert the bathroom adjacent to the kitchen into a utility room. We approached Open Plan Design and received the most amazing service one could ever wish for right from the start to finish. The team led by Mr Ali were able to wonderfully convert our raw ideas efficiently into detailed 3D perspectives and adjust the specification to meet our needs and expectations. The attention given to delicate details to ensure every aspect was covered and approved was outstanding and the entire project management was carried out meticulously and on time. We are extremely pleased with the workmanship and the quality of the German kitchen installed. Hassan who is the master fitter at Open Plan Design, is the most approachable and knowledgeable person and went beyond to satisfy us. With any big projects there is one or two little niggles that could emerge after installation and ours was no exception. Again, the team responded swiftly to rectify them. I wholeheartedly recommend this company to anyone who wishes to achieve quality results and peace of mind with their renovation projects.
Customer service was some of the best I’ve experienced. Sam was so very accommodating and helped design us a great kitchen. We ended with a design no other company thought of. The prices are great and the facilities ensure a smooth process, with themselves handling all the work involved. They provide an all-round wonderful service.
Top-quality German kitchen. Great customer service. Really happy. Bought my first german kitchen and it turned out amazing.
Absolutely impeccable service, by far the best service I’ve received from anyone trying to sell me something! You were so incredibly patient, helpful and friendly, willing to offer expert advice on what would look best and waited patiently as I made up my mind. Thank you for offering me ideas on how to cut costs and bringing my fitting day up to a closer date. Mohammed, thank you so much for such a pleasant experience in such a stressful time with my new kitchen! I hope your business continues to thrive, you deserve it!
Openplan showed us various designs and more importantly made suggestions on the types of worktops to use for the kitchen. We were spoilt for choice and ultimately got the style, colour and design we wanted. The worktop was cut using the latest design in technology and delivered and installed professionally. We also got a dining table made. Highly recommended for their products, services and advice.
