For GROPYUS Building OS, a tenant-facing control center for connected apartments, we defined a bold, Swiss-inspired visual language in four weeks while key product features were still evolving. In parallel, we fixed critical usability issues in the existing experience and laid the groundwork for a scalable design system.

In four weeks, we shaped a bold, Swiss-inspired visual direction for GROPYUS Building OS, the tenant-facing control center for connected apartments, while the product was still evolving. Alongside the new look and feel, we addressed key usability gaps and established a scalable design system foundation. The existing experience struggled in real use. Device controls relied on hidden actions like press-and-hold, and blind controls used complex gestures that looked refined but were difficult to understand quickly. Sustainability content was also generic, with little direction on what residents could actually do to improve their impact. We aligned closely with product, research, and engineering to move fast without losing coherence. The system is anchored by a reusable card component that flexes across the app to organize content and actions consistently, making controls clearer today and ready for future modules like consumption history, sustainability insights, and internet booking.
