Why this style worksDark timber against dark stone works for a reason unrelated to taste: an office is lit by artificial light for the whole working day, at levels no home reaches, and mid-tones go grey and flat under 4000K. Depth is what keeps a surface reading as material rather than laminate. It survives the traffic too — a reception counter is touched by every visitor and every staff member arriving, which is a rate of contact no domestic surface sees, and dark, low-movement surfaces absorb that wear instead of recording it.
Approved sourcing matrixOne approved build, component by component.
One approved way to build the Corporate & Commercial language — dark timber and stone on sealed plinths, one base metal finish across the floor, privacy glass banded at seated eye level, with floor, paint, blinds, lighting and acoustics to the ELS requirement.
| Component | Route | ELS specification | Status |
|---|
| Cabinetry & joinery | ALUMAX | Walnut, smoked oak or controlled medium timber on a SEALED aluminium or stone plinth (contract cleaners wet-mop daily; a timber base wicks water and swells within two years).ALUMAX code confirmed on the finishes catalogue. | Primary |
|---|
| Pantry sink run (wet) | ALUMAX | ACP or aluminium substrate on the sink run (no cooking but no extract, and AC is off Friday to Monday — it meets water without drying); P6 board only to genuinely dry runs.ALUMAX code confirmed on the finishes catalogue. | Conditional |
|---|
| Reception / meeting top | ALUMAX | Honed or leathered dark stone (polished records every water ring and fingerprint under reception downlights); cable routes fixed at carcass-drawing stage.ALUMAX code confirmed on the finishes catalogue.Approved equivalent: A specialist-supplied honed dark quartz of the same depth is an accepted equivalent. | Supporting |
|---|
| Metal & hardware | ALUMAX | Matte black, graphite or dark bronze aluminium — one base finish shared across meeting and executive seating (chrome legs against graphite read as two projects).ALUMAX code confirmed on the finishes catalogue. | Accent-only |
|---|
| Glass & partitions | ALUMAX | Clear, smoked or fluted privacy glass; flute or band the meeting-room glass at SEATED eye level (staff avoid a room they cannot sit in unseen) while keeping the borrowed daylight.ALUMAX code confirmed on the finishes catalogue. | Conditional |
|---|
| Floor | Specialist trade | Dark or mid porcelain, 600×1200mm or 600×600mm, matt, rectified, R10 minimum (R11 to entry and wet), heavy commercial-traffic rating (PEI ≥4), ≤3mm grout. | Supporting |
|---|
| Wall paint | Specialist trade | Charcoal, warm grey or off-white — feature LRV 15–25, general LRV 55–70; matt or eggshell washable, low-VOC, scrubbable to contract-cleaning. | Sample hold |
|---|
| Window blinds | Specialist trade | Solar-control or Low-E glass plus external shading where the facade allows; chain-operated roller blinds for the last hour of sun only — no fabric drapes (contract cleaning never washes them). | Supporting |
|---|
| Lighting | Specialist trade | One colour temperature in 3500–4000K and one CRI (≥90) across the whole floor; a vertical bias so faces read on video calls; never a downlight directly above a monitor. | Conditional |
|---|
| Acoustic treatment | Specialist trade | One absorbent plane in every enclosed meeting room — dark stone, glass and plasterboard make an acoustically hard box; without it video calls clip and voices carry to the open floor. | Conditional |
