INTER
WORLD

by Iryna Chernikova

One restaurant. Two worlds. Above the lake — open sky, wind, horizon.
Below the lake — the living underwater world,
seen through a full-length glass wall.

Nothing like this exists anywhere in the world.

Level One

Upper World

An open natural terrace at the water's edge. White river stones. Wild grass. Low seating covered with natural fur. Canvas shade sails. The lake at eye level. The sky above. Nothing between the guest and the landscape.

Open air · natural light
Lake surface at eye level
Unmediated natural environment
Wind · sound · horizon
Level Two

Lower World

Carved into the shoreline, below the waterline. Raw concrete walls and low ceiling. A full-length panoramic glass wall opens directly into the living underwater ecosystem of the lake. A central fireplace. Stillness and fire in the same room.

The Connection

The transition is part of the experience.

Between the two worlds — a descent through the shoreline. Not a corridor. An architectural threshold. The sky disappears behind the guest. The water appears ahead. The same lake, observed from two opposite sides.

01
Upper World Open air. Natural landscape. The lake at eye level.
02
The Descent A ramp through the shoreline. Concrete. Darkness. Stillness.
03
Lower World Below the waterline. The lake, seen from within.
Same lake. Two perspectives. One evening.

Other projects give guests one world.
INTERWORLD gives guests two — above the waterline and below it —
observing the same lake from opposite sides, in one evening.
