Who we are
Haus Roni
Kitchens and construction from one source.

Haus Roni. Kitchens and construction from one source.
Roni is a family name. And that is how we work: determined that our name should stand for what we hand over.
In Cologne we are new. In our trade we are not. Behind Haus Roni stand the manufacturing strength of our partner works and more than 250 completed projects. That is the experience we bring to the Rhine.
We design kitchens to measure and have them made for you at our partner works. No off-the-shelf runs, no compromises over millimetres: every kitchen is built for exactly one room and exactly one household. Materials, layout and details we develop together with you, supported by our interior design planning.
A project rarely ends at the kitchen run. That is why Roni Bau is a fixed part of what we do. Bathrooms, tiling, floors, drywall, complete flat and house renovations: our civil engineer and our own tradespeople build what was planned. You have one point of contact, one schedule and one responsibility — from the first survey to the handover.
From Cologne we work throughout Germany as well as in the Netherlands, Belgium and France, with kitchens just as with construction.
Visit us in our showroom in Cologne, or we will come to you: arrange a free first consultation or an on-site survey. We listen, we measure, and we tell you honestly what is possible.

How we want to be judged
- 01
Fixed price
What the quote says is what the invoice says.
- 02
On schedule
We name a date only once we can keep it.
- 03
Craft
Our own fitters, not a rotating cast of subcontractors.
- 04
Clean handover
When we say swept clean, we mean clean.

Testimonials
What our clients say
The kitchen was in within a day, exactly as it looked on screen. What surprised us: the fitters mopped the floor on their way out.
Familie BrinkmannPrivate client, Düsseldorf We needed an office kitchen for 120 people that still works at noon. Roni thought about circulation, not just the doors.
Christine VogtOffice management, technology company The shell and the kitchen coming from the same people sounds like a detail. In practice it means the socket sits where it belongs.
Hendrik BaumannClient, house with kitchen One contact for fourteen trades. That helped my calendar more than any piece of software.
