Less frame.
More life.

The SL55 Infinity is a top-notch proposal for structures in absolute minimal design. All design elements strive to convey the message of simplicity, allowing light, form, material, space, and nature to provide the very best of living conditions.

Carefully applied minimalist principles create greater freedom for developers and architects — with more comfort, more style and infinite views.
