Brutalist Concrete + Plant

// raw aggregate meets living greenery — a design system

Color Palette

Drawn from poured concrete, exposed aggregate, and the tropical plants that soften brutalist interiors. Greys provide structure; greens bring life.

Brutalist architecture values raw materials and structural honesty. When plants colonize these concrete surfaces, the tension between the engineered and the organic produces something unexpectedly beautiful. This design system captures that interplay.

Spacing

A power-of-two scale rooted in a 4px base unit. Like formwork modules, each step doubles the previous.

Buttons

Heavy borders and hard shadows. Like concrete blocks stacked with purpose. The leaf marker on primary actions signals growth.

Variants

Sizes

Forms

Inputs sit in inset shadows, as if cast into the concrete surface. Focus states glow green, like bioluminescence through cracks.

The working title for this structure

Cards

Content blocks like concrete modules — stacked, rigid, honest. Plants peek from the edges, softening the brutality.

Barbican Conservatory

A tropical oasis hidden inside London's most famous brutalist complex. Over 2,000 species of plants thrive among raw concrete.

Architecture Plants

Vertical Green Walls

Hydroponic systems mounted directly onto board-formed concrete facades. The roots find their way through every crack.

Green Infrastructure

Aggregate Specification

Exposed aggregate finishes require careful selection of stone size, color, and distribution. The surface tells the story of what lies within.

Material Technical

Alerts

Notifications marked with colored rebar strips along the left edge. Urgent messages read like site safety notices.

Growth Detected New root systems have established in expansion joints along the east facade. Structural integrity confirmed.
Moisture Warning Humidity levels in Section B exceed 85%. Verify waterproofing membrane before proceeding with planting.
Structural Alert Root penetration detected in load-bearing column C-14. Immediate assessment required.
Specification Note Board-formed concrete finish Type III selected for interior atrium walls. Grain direction: vertical.

Code

Technical specifications rendered in monospace, like construction documents on dark concrete.
