Off-form concrete — the raw, board-marked concrete look you've seen in modern Singapore homes and cafés — is one of the most distinctive finishes you can specify. It's also one of the most misunderstood when it comes to cost. This guide explains what drives the price, how it compares to polished concrete, and what to budget for in 2026.
At Unique Interior Design, off-form and decorative concrete is one of our core specialisms, so we've put together the factors that actually move the number on a quote.
What is off-form concrete?
"Off-form" refers to the surface left behind when concrete is cast against formwork (the timber or steel mould). Done well, it carries the texture of the boards and the honest, monolithic look that defines industrial and contemporary interiors. In renovation, the same look is often achieved as a decorative concrete finish applied over existing walls and floors, which is faster and lighter than a full structural pour.
What drives the cost?
There's no single price per square foot, because the finish is highly project-specific. These are the biggest cost levers — in rough order of impact:
As an indicative market range, applied decorative concrete finishes in Singapore commonly fall somewhere around $12–$30 per square foot installed, depending on the finish and preparation involved. Treat that as a starting reference only — your exact price depends on the factors above, which is why we quote per project.
Off-form concrete vs. polished concrete
These two are often confused. They're different finishes with different looks, costs and ideal uses:
| Off-form concrete | Polished concrete | |
|---|---|---|
| Look | Raw, board-marked, matte | Smooth, sheen, speckled aggregate |
| Where | Feature walls, ceilings, counters | Mainly floors |
| Strength | Statement texture & character | Durability & easy cleaning |
| Cost level | $$–$$$ | $$ |
| Best for | Industrial / contemporary feature surfaces | High-traffic open-plan floors |
How to budget sensibly
- Start with the area and the finish — a small feature wall and a full open-plan floor are very different jobs.
- Account for prep — uneven or damaged substrates add labour before any finish goes on.
- Include sealing in the quote, not as an afterthought.
- Ask to see real samples — concrete finishes vary between contractors.
Yes — most commonly as an applied decorative finish on a feature wall or a TV console backdrop, which avoids the weight and structural considerations of a full pour.
Fine hairline variation is part of the material's character. Proper substrate preparation and sealing keep it stable and easy to maintain.
An applied feature finish is typically a few days including curing and sealing; larger or cast work takes longer. We confirm the timeline at quoting.
