kube story

Kube-asemalla0001pienikube designer lamps are skillfully handmade of concrete

The timeless kube concrete lamps made by designer Petri Seuri are suitable for both home and public environments.

The workshop of designer Petri Seuri, where the kube design lamps as well as wooden furniture are made, faces a modern log house in the middle of a rural landscape in Southwestern Finland.

Why did the carpenter/designer pick concrete as his raw material to work on?

Concrete as material has intrigued me since I was a designer student. The idea for the kube lamp came to me as I was looking at some casts for concrete at a construction site. Although concrete is an extremely easily formable material, to successfully make small-sized items of it requires a lot of practice – and also good nerves, Seuri says and smiles.

Product development for the lamp has involved a lot of work in finding the correct feel and quality of the material as well as developing the necessary tools. The work has paid off – although the lamp looks impressive, its only 8mm thick edges bring lightness to the design. It is the classic cubic form that is a challenge to produce; Seuri says that casting a round object would be much easier.

The mixing ratio of the raw materials has significant effect on both the color of the product and the casting work. The ingredients have to be measured by the gram.


Variations are allowed in the surface, not in the form

When thinking about concrete, the building of suburbs in the 70’s may spring to mind. However, the versatile material has made its return in the modern architecture and interior design. Seuri says that concrete is especially well suited for interior decor because of its diverse properties. The material for example imitates the surface of its casting mold.


If a wooden mold is used, the concrete surface becomes porous and the branch spots of the mold leave a print, whereas a glass mold produces a perfectly smooth surface. Seuri uses metal molds for the kube lamps and works hard to make the product surface look uneven. Small air bubbles are a must in the finished product surface.

The edges have to be perfect of course, but small irregularities on the side surfaces bring intriguing details to the lamps. No two lamps are identical, Seuri promises.

The kube lamp, with its shape and organic surface, is naturally suitable for many types of furnishings in both home and public environments. Indirect lighting is effective in highlighting the outlines of indoor spaces, and the wall lamp is available in different models directing light in either one or two directions. The collection also includes pendant and table lamps.

– The color of the kube lamp shade also has an effect on the color of the light produced. The terracotta and sand colored lamps give the light softer tones, while the grey lamps produce a colder toned light, Seuri describes.

The lamps can be customized according to preferences – choices can be made between black or rusty metal parts, and there are also color options for the textile covered power cord. The smaller, kube 100 model (100mm), is available as a table or pendant lamp, and the larger, kube 125 model (125mm), as a table, pendant, or wall lamp.
