An electronically operated folding door lifts effortlessly to reveal the complete work area and disappears entirely from view, allowing the kitchen to transition elegantly between function and form.
On/Off St
On-Off ST is a sophisticated kitchen system that seamlessly blends advanced technology with minimalist architecture. Designed by Alberto Colonello, its distinctive self-standing structure conceals the entire working area behind an electronically operated folding door, transforming the kitchen from a fully equipped workspace into a refined monolithic volume. Every detail is engineered to enhance functionality while preserving the clean, architectural aesthetic that defines Boffi.
It's beautiful closed and open. It's like one big container, equipped with a "window" that opens onto the worktop equipped with everything. Highly modular.
