Innovative & Design-led Architectural Design Practice in London

Open Volume Studio is a boutique architectural design practice, capable of working on projects of all size from very large new build projects to tiny loft conversions. With particularly close attention to the use of light, design and the home environment, coupled with our environmental and material research interests, we aim to provide projects which can add value and implement meaningful change in the lives of our clients. Ultimately, we want to create beautiful spaces, with elegance and to a high standard. These spaces are the expression of our clients; a back drop to their lives that can subtly enhance the way they live when designed well. Our promise is to always listen. We listen and interpret, work and rework, until our clients have truly achieved everything they dream of and more. Research is also an important part of OLJ Designs Ltd as we continue to grow and aim to push the boundaries both within architectural academia and in our built environment. Olivier Jauniaux's personal research on one side focus's on Architecture's historical relationship to philosophy and politics and on the other is deeply engaged in how light and materiality can be used to change the atmosphere and our experience of architecture within the city. Olivier Jauniaux graduated from the Architectural Association School of Architecture in London with Commendation and RIBA Part II. Having already set up his practice to support his studies, Olivier has mastered an ability to work creatively on many projects of different kinds, managing complex briefs and solving problems at every scale.

Highly highly recommend. Olivier completed the drawings and design for my loft conversion, rear dormer, first floor extension, and ground floor side return in a timely manner and to a really great standard. He imposed his own design view, added material value throughout the process and would absolutely use him for any future projects.

Olivier has helped us convert and extend our Victorian terrace house to adapt it to modern living. He’s been very dedicated, and has brought lots of great ideas and features which make our house stand out from the typical conversions. He has designed it, sourced products, recommended tradesmen and project managed the build. He’s got an excellent eye for detail, is creative and professional. Our house is now very bright, airy and yet filled with traditional features. We couldn’t be happier with the end result and would highly recommend Olivier’s services.

I have worked with Olivier on several projects now and he has been very professional and easy to work with. He provides an amazing service and he is a great designer. I have worked with him both on a traditional country house and on a really contemporary mews house project. He has been excellent at designing both.

My husband and I hired OLJ designs to design our build for 6 duplex apartments on our property in Hamilton, New Zealand.. We were absolutely delighted with the stylish modern and efficient design they developed. The design was airy and light, taking full advantage of the gorgeous valley views and utilised space in a creative and innovative manner. Olivier Jauniaux, was at all times professional and knowledgeable. He was always available and listened to what we wanted. We were extremely pleased with his approach in all aspects of his commission and would highly recommend him to any other potential clients as someone who will work hard to achieve a design you will be delighted with.

Olivier Jauniaux designed an extension to my house in which a pool was built and the roof of which became a roof garden. This was quite a complicated project as it required specific dimensions, decisions regarding humidity control inside and the build of a waterproof roof garden. We are very pleased with the result. Clearly Olivier listened to us and obtained something that suits our needs perfectly.

I hired OLJ Design for an extension to the back of our house. The design was crafted to our needs and is inspiring to experience and live in. We enjoyed working with such a professional company and it was fun to be able to get involved in every aspect of the process. The end result really exceeds our expectations and we’re incredibly happy to have worked with such a creative company. I would highly recommend OLJ Designs to all my friends.

Olivier cares about creating something unique, not just the idenitikit extension that so many of the big D&B firms present. Some unique features make our property stand out from the crowd.

Olivier has been an amazing inspiration, support and problem solver throughout our renovation of a ground floor flat in a Victorian terrace in South London. The initial process involved a detailed consultation and investigation of the property to assess our needs and the possibilities of our new home. Olivier has a professional but friendly manner, with a reassuring confidence and good communication. We immediately loved his designs and ideas for our space, and appreciated him really listening to our own ideas and input. His recommendations for tradesmen were solid and he had an excellent working relationship with all parties and trades. He made the whole process clear and offered pragmatic solutions throughout the project. We are thrilled with our new home and thankful to have been creatively guided through the process by such a talented architectural designer.
