GRUNDFORM
A furniture brand and commerce platform built on the original language of functional design — primaries, primitives and an unforgiving grid.
01 · The Brief
A furniture brand,
reduced to essentials.
GRUNDFORM makes geometric, function-first furniture. They needed an identity as honest as the objects — so we built it on the original language of functional design.

02 · The Style
Why Bauhaus fits a furniturebrand.
The Bauhaus didn't just theorise modern design — it built the furniture. Breuer's tubular-steel chairs, Brandt's lamps, the Wassily — all came out of its workshops between 1919 and 1933.
Its rules are GRUNDFORM's rules: form follows function, ornament removed, every shape earning its place. A brand selling reduction should speak in a reduced language — true primaries, hard geometry, and an unforgiving grid.
The shared brief
Function before decoration
Honest materials & structure
Made for industry, at scale
03 · Principles
Four rules, carried into every pixel.
Form follows function
Nothing decorative. Every element does a job — or it's removed.
Geometry as language
Circle = movement, square = grounding, triangle = direction. Shapes carry meaning.
Primaries + black on neutral
Red, blue, yellow and ink. No pastels, no gradients, no more than three hues.
Flat & structural
Zero radius, no shadow, 3px ink rules. The grid is the ornament.
04 · Overview
GRUNDFORM makes geometric, function-first furniture — and needed an identity as honest as the objects.
We rebuilt the brand, storefront and mobile app on a single Bauhaus design system: true red-blue-yellow, hard geometry and 3px ink rules, with zero rounded corners by design.
One component kit now drives every surface — from the marketing site to checkout to the operations dashboard — so a three-person team ships consistently and fast.
05 · Use Cases
What people do with it.
As a shopper
I want to browse and buy in a few taps so I can furnish my home without the friction of a clunky store.
As an interior designer
I want to filter by material and dimension so I can specify the right pieces for a client, fast.
As the studio team
I want to manage orders and stock in one place so the shop runs without spreadsheets.

A geometric grotesque — the closest free relative of Futura, the Bauhaus's own typeface. Circular bowls, even strokes, set bold, uppercase and tracked so type behaves like another primitive.

Before colour,
the bones.
Every screen sketched in mono — boxes, hatch and rule — to settle hierarchy before the kit is bolted on. No primaries, no type weight decisions, no surface treatment: only what goes where, and at what density.

Bauhaus DS × GRUNDFORM
Thank you
A small studio in Berlin, three rules from a century ago, and the quiet satisfaction of nothing left over. Thank you for spending time inside it.
