Signbox was commissioned by Brown Brothers Harriman (BBH) to transform the internal glazing across their London offices at 10 Exchange Square. The client wanted a bespoke solution that modernised the workplace, introduced subtle privacy within meeting and office spaces, and reflected both the firm’s heritage and its London location. Through innovative design, expert craftsmanship, and precision installation, Signbox delivered a cohesive glazing scheme that balances functionality, brand storytelling, and architectural elegance.

Signbox developed three distinct design sets to provide variety while maintaining a consistent visual language across the office:
- Handwritten Script
- Featured the company name in a refined script style.
