Material and precision, Romanshorn Switzerland

This kitchen was planned and realised by Ruf Design. It combines technical sophistication with a powerful materiality. The room is characterised by clear lines, dark accents and an architectural calm that is further enhanced by the choice of materials.

Islands of metal and lava

The two islands form the centre of the kitchen. Each island consists of a metal construction that conveys stability and lightness at the same time. A solid-looking lava slab serves as a cover, its depth and glossy surface giving the room a special presence. The edges are softly moulded and show the precision craftsmanship with which the stone was processed.

Beneath the metal structure is a carcase made of fine wood with spacious drawers. They provide space for pans, utensils and cooking utensils and create a functional counterpoint to the elegance of the lava slabs.

Cooking the invisible way

An Invisacook system is integrated into the lava plates. It is operated via a control panel that can be pulled out to the side and is only visible when it is needed. This leaves the cooking surfaces completely free. The top can be used as a work surface, presentation surface or dining table without revealing its technical function.

Kitchen as a room composition

The surrounding base units are in a deep, matt green colour and create a calm base for the entire composition. The walls remain light-coloured, allowing the dark units and glossy lava worktops to create a strong spatial effect. The kitchen is complemented by an illuminated glass cabinet, which displays glasses and crockery in a warm light and characterises the atmosphere of the room.

Ruf Design Planning and realisation


This kitchen shows how material and technology can merge in a clear architectural language. Ruf Design was responsible for the entire planning, construction and assembly. The result is a space that is both functional and sculptural and impressively demonstrates the possibilities of the material lava.
