Fos Studio.

A staircase that moves.
Because staying still was too easy.

Every great idea starts with play.

Inspired by the construction toys that sparked our imagination as kids, this staircase transforms childhood curiosity into a functional architectural object.

It wasn’t born for a single project. It was built to stay.

Suspended from an overhead rail, it slides effortlessly across the space, challenging the conventional way we move through architecture.

Now available as a FOS product.
And soon, you’ll discover the project where it all began.
