Open Volume Studio

Open Volume Studio OLJ Designs is a boutique architectural design practice, capable of working on projects of all size from very large school to tiny loft conversions.

I am Olivier Jauniaux, a sole trader and founder of OLJ Designs. I currently student at the Architectural Association in order to complete my Part II diploma and in the mean time I am working to support my studies. I trained at, in my opinion, one of the best small residential architecture firms in London; KSKa Architects. Under Matthew Keeler, a very experienced and talented architect and had the

honour of learning directly from him and his wealth of experience. Now I am working to build up a portfolio, taking on a very limited number of project which I am passionate about and invest as much time and effort as is necessary to get them to the highest level of finish that I can achieve.

We are hiring… but differently.

If you don’t answer the points in the description, we won’t reply. So bother reading the carousel. All the info and hints are there. It’s not *that* long.

If you match the vibe…. And the requirements, I’d love to meet you. If your vibe is right but for the rest you are only most of the way there, very happy to chat.

Just don’t send me your batch emails. I’m looking for a partner, not a cad monkey 🐵 Your applications need to be tailored.

See you on the other side.

The devil, as always, is in the details!

Our recently completed flat interiors in Belsize Park are no different, including in transforming unit carcasses into a bespoke piece of fitted joinery below the TV! Check out our other details in our subtle touches of colour, highlights, shadows and threshold textures that transformed an outdated flat into something calm, fresh and contemporary, full of light.

A bit late showing you this!

Here is our recently completed beautiful interiors project in Belsize Park! In this project I feel like I’ve rediscovered an appreciation for bold colours. I’ve never shy’d away from a bit of colour, particularly in a couple of our previous projects like the Method Office, but here we went bold in the bathroom and look how it glows.
The rest of the flat has touches of colour amongst a warm light palette creating a beautiful environment for our clients and their new born baby!
So pleased with how this turned out and I wish the best of luck and love to the new family!

Everyone told us it was impossible. But…

We got planning!! 🎉 This is a two story rear extension to a Grade II listed building in Maida Vale conservation area overlooking locally protected housing. Including some pretty substantial internal alterations. That’s another pretty tricky combo we’ve successfully ticked ✅ off! Listed building consent also received of course!

We’re pretty chuffed with this one. Not going to lie, even me, in my eternal optimism, was borderline unsure we would be successful… but with hard work from the whole team, resilience and an amazing client we achieve the ‘impossible’ once more. The Westminster planning team were particularly hard work this time… ⭐ ⭐ but we got there in the end.

If you have any questions about your planning applications or a difficult site that needs looking at, please reach out! We are taking on new clients!
