The Horizon Pinnacle: Lighting a Landmark Atrium in Riyadh

An international investment fund commissioned us for The Horizon Pinnacle, a flagship commercial office in Riyadh's ultra-modern Al-Malqa district. This is landmark-scale corporate architecture, and the brief was to turn raw technical drawings into a design-led workspace convincing enough to drive high-value institutional leasing before construction started.

Selling prime office space before it exists is exactly what my studio is built for. This one just came at landmark scale, with a cavernous multi-storey atrium at the centre of it.

The atrium was the whole job

Most of the difficulty lived in one space. A double-height, multi-level atrium with sweeping curved staircases twisting between floors, floor-to-ceiling glass balustrades and deeply polished marble. Get the atrium right and the building reads as the landmark it's meant to be. Get it wrong and the most expensive gesture in the scheme falls flat.

The materials made it harder. Sweeping curved stairs, double-height glass facades, highly polished floors, all under direct sunlight pouring from expansive skylights. That combination is a render minefield: skylight sun hits a polished marble floor and either blooms into flat white glare or turns the floor into a mirror that erases the stone. Either way you lose the surface clarity that signals quality.

So we scripted the materials carefully, the grain of the light oak panelling, the matte of the continuous acoustic ceilings, the crisp reflections on the large-format white marble tiles, then built the lighting as a matrix. Skylight daylight balanced against warm LED perimeter tracks, strip lighting hidden inside the floating staircases, and minimal directional downlights. I gave the staircase strips a touch more presence than a photo would, because in a still image those curves need an edge of light to read as sculpture rather than a grey ramp.

How the floor plates work

Around the atrium the plan is practical. Elevated collaboration links, open bridges and mezzanines overlooking the void, fitted with long oak workbenches and timber screening to define breakout zones. Agile hot-desking clusters sit parallel to the massive glazing, using planters as natural dividers so the focus areas get daylight without feeling exposed.

A position I'll hold: a big atrium is where landmark offices most often overspend on render drama and undersell the actual workspace. The tenant signing the lease works on the floor plates, not in the void. We gave the atrium its moment, then spent real effort making the working areas look like places you'd want to spend a Tuesday.

What I'll leave to others

I can speak to how we made the space read as a landmark and a workable office at once. What I won't claim is a read on Riyadh's institutional leasing market or how a Saudi fund weighs a flagship address. We served the visualisation; the market call was the client's.

The result

The set gave the development team a decisive B2B marketing asset. By showing exactly how the spatial moves, the skylight daylight and the premium stone behave under real conditions, it took the guesswork out of the pitch, let procurement order finishes early, and shortened the pre-leasing cycle.
