Bespoke Concrete Colours & Finishes

Artisan Concrete Textures for Modern Interiors

At Gumi Works, we push the boundaries of artisan concrete casting to create a palette that is both architecturally striking and tactilely warm. Our finishes are not merely surface treatments; they are deeply integrated into the material's composition, ensuring a durable, UV-stable, and high-performance result for both indoor and outdoor bespoke furniture.

Our Signature Concrete Finish Collections

Whether you are specifying a minimalist concrete dining table or a commercial reception desk, our range of hand-refined finishes offers endless design possibilities:

  • Solid Pigmented Concrete:

A clean, monolithic concrete aesthetic available in a wide spectrum of earth tones and architectural greys. Beyond its minimalist surface, a refined “salt-and-pepper” texture emerges once the concrete polished, revealing the delicate interplay of micro-sized crushed glass and fine sand exposure. This subtle depth transforms a singular solid color into a sophisticated, high-performance finish that celebrates the raw, honest character of the material.

High-performance solid polished terracotta colour concrete finish for architectural surfaces and worktops.

  • Polished Terrazzo Concrete:

A stunning fusion of high-performance concrete and curated aggregates. We don’t limit your palette; we work with crushed colored glass, marble, granite chippings, and varied natural stone aggregates to meet your specific design vision. Each surface is processed  to reveal a truly bespoke terrazzo finish tailored to the creativity of your project.

  • Hand-Packed Marble Effect (Pressed Finish):

Our most artisanal finish, achieved through a manual ‘hand-packing’ technique. This process creates organic, cloud-like veining and tonal shifts that are unique to every cast. It captures the raw, industrial soul of concrete while offering a sophisticated, marble-inspired aesthetic for bespoke furniture and surfaces.

Engineered for Performance

All our GFRC (Glass Fibre Reinforced Concrete) pieces are finished with a professional-grade, penetrating sealer. This ensures your custom concrete surface is highly stain-resistant and weather-ready, making it ideal for everything from high-traffic kitchen worktops to sculptural garden furniture.

Concrete Colours | Inspired by Nature

Our colour range is rooted in the subtle tones of the natural world—from warm earth clays to misty greys and charred woodland charcoal. Each hue is developed by hand in our London studio, designed to create tactile, balanced pieces.

Whether for a polished concrete dining table, a bespoke basin, or an outdoor feature, our 20 curated colours are designed to work across Solid, Hand-Packed (Veined), and Terrazzo finishes.
We have grouped our shades below to help you visualize tone and contrast.
