“Threshold of Change” Installation

The “Threshold of Change”, designed by Harsha Kotak for the 2026 Sustainable Design Forum, served as an entry-point archway that introduced the event’s core themes the moment visitors arrived to the Crypt on the Green. 

The temporary structure, or “sculptural intervention,” as Harsha calls it, was built from our modular U-Build components, including our diamond cut-out columns and stage boxes. It provided a physical gateway and a poignant conversation starter, addressing the reality that construction waste is a direct byproduct of specification, procurement and delivery choices, issues commonplace in the industry that rethinking and redesigning has the power to undo.

Constructed using modular timber, reclaimed textiles and living plants, the plywood structure required attendees to walk through the portal to enter the event, contrasting a visible mound of textile waste on one side with a hanging veil of woven fabric flowers on the other. Visitors were encouraged to pause and face the real-world impact of wasteful design decisions before entering the wider event. 

The project demonstrates the practical value of reusable timber systems and the necessity of repurposing materials that already exist around us – all parts of the demountable arch were sourced from our Box Library and have been returned and reused for a number of diverse temporary projects since.

Rather than surface-level decor, the intentional configuration of our plwyood boxes highlights the importance of low-waste, circular materials to counter everyday environmental impacts, alongside the significance of thought-provoking, responsible use of space.
