Built-in furniture that fits your life, not the other way around

We are a joinery studio on the Prinsengracht, Amsterdam, specialising in wardrobes, kitchens, and fitted offices that are designed around how you actually live and work. Every piece is drawn, built, and installed by our own team — no subcontractors, no catalogue shortcuts.

"They turned an awkward alcove into the best room in the house. The drawers glide, the doors sit flush, and it still looks new three years later."

Custom joinery for homes and workplaces across the Randstad

Onicostrap started as a two-person workshop and grew into a full studio because clients kept asking for the same thing: furniture that uses every centimetre without looking cramped. We measure on site, model in 3D, and build in our workshop before returning to install — usually within six to ten weeks from sign-off.

Whether you need floor-to-ceiling storage in a canal-house bedroom or a reception desk that hides cables and coats, we treat each project as a one-off. Materials are sourced from FSC-certified suppliers across the Netherlands and northern Europe, and we finish everything by hand so the grain and colour stay consistent.

Most fitted furniture companies sell a system and adapt it to your room. We do the opposite: we start with your room, your habits, and your budget, then design something that belongs there. That means honest timelines, fixed quotes after the design phase, and a single point of contact from first sketch to final hinge adjustment.

Our workshop is fifteen minutes from the city centre, so you can visit during production and see your cabinets before they are lacquered. Many Amsterdam clients appreciate that transparency — especially when renovating a monument-listed property where every millimetre counts.

Built-in storage

Floor-to-ceiling wardrobes, hallway cupboards, and under-stair solutions tailored to awkward Dutch ceiling angles. We integrate lighting, shoe racks, and soft-close hardware so daily routines feel effortless rather than fiddly.

Kitchen joinery

Handleless fronts, solid oak worktops, and appliance housings that respect the proportions of older Amsterdam kitchens. We coordinate with your plumber and electrician so the install week runs smoothly.

Office fitted furniture

Reception desks, meeting-room storage, and home-office wall units built for cable management and acoustic privacy. Ideal for scale-ups moving into their first proper office on the Zuidas or a converted loft.

From first measurement to final polish

Our process is deliberately straightforward because renovation stress is real. You get a site visit, a written brief, a 3D proposal, and a fixed price before we cut a single panel.

Installation teams work in dust sheets and leave the space broom-clean. We return once after two weeks for hinge tuning and touch-ups — included in every contract.
