Beneath the Nebulae Shala

Hidden beneath
the water.

Below the Nebulae Shala, one of the most immersive chapters of the entire ecosystem begins. Woven into the architecture above and concealed beneath the surface of the pool, the Water Cube Suite explores the meeting point of geometry, light, marble and atmosphere.

The result is an experience that feels at once intimate, futuristic, and entirely its own — a place you descend into rather than simply enter.

Where the name begins

The Cube and the water.

The suite draws its name from two defining elements of the project: the iconic Cube sculpture that has become the visual signature of Nebulae, and the body of water that embraces the space itself.

Together they shaped an architecture rooted in immersion, reflection and sensory exploration — a dialogue between solid form and moving light.

One space · two atmospheres

By day,
light on water.

Sunlight falls across the water above and scatters through the interior, tracing slow reflections over marble and concrete. The suite feels calm, luminous and restorative — open to the landscape it hides beneath.

By night,
a spectrum.

After dark, everything shifts. Programmable architectural lighting moves the suite through moods and colors, revealing a cinematic dimension where geometry glows and the water turns to light.

This transformation lies at the heart of the project.

A language of form

Cube, circle, triangle, line.

At its core, Water Cube is an exploration of geometry in its purest form. The most fundamental shapes recur throughout the architecture — proof that clarity, proportion and materiality can generate spaces that feel elegant, contemporary and quietly emotional. Nothing is ornament; everything is structure.

Materiality

Marble, concrete, water, light.

Marble runs through the suite in sculptural details, custom furnishings and architectural compositions. Set against exposed concrete, integrated lighting and the reflections of the surrounding water, it creates a material language that is both refined and deeply immersive.

At the water's edge

A lounge beneath the surface.

The suite opens onto one of the property's most singular spaces — a submerged outdoor lounge poised at the edge of the pool. Suspended between architecture and water, it offers a perspective of Nebulae you will find nowhere else.

Atmosphere, engineered

Tuned for light
and sound.

An integrated high-fidelity sound system binds architecture, music and emotion into a single experience, while considered acoustic design holds a sense of privacy and calm.

Inhabit the space completely — and stay connected to the quiet of the landscape around it.
