OST interior is an architecture design studio that manages projects in-house from creation to realisation.

We design and build complete interiors and products for private and professional clients. We focus on restaurants and bars but don’t shy away from hotels, gyms, offices and residential projects. We approach all these projects with a design twist that finds its origin in our restaurant and bar designs.

Oneseventree believes that good design does not only exist on paper. Designers give the carpenters input and vice versa. This interaction between design and execution gives the best outcome possible.

Next to our team of designers we have our own team of (Freelance) builders, carpenters, welders, electricians and plumbers. With this team Oneseventree can be your one-stop-shop for your project; developing concept and design, supervising construction and managing the complete project process.
