The Portman Estate head office: Heritage workspace transformation for people and planet
 
Wed 13 May 2026, 13:10-14:05
Interiors Focus Stage
FOOTPRINT+ Old Billingsgate, London

The Portman Estate’s relocation of its head office to One Great Cumberland Place presented an exciting opportunity to reimagine the workplace. The project aims to set a benchmark for sustainable commercial interiors across its 110-acre Marylebone estate.
 
The retrofit of the 8,400 sq ft office prioritises collaboration, wellbeing, and exemplary environmental performance while working within an existing base build. Sustainability informed every design decision including:

- low-carbon and high-recycled-content materials
- circular economy principles resulting in reuse of existing services, lighting, and finishes
- inventive reuse of salvaged materials
- specification of furniture to meet rigorous environmental, repair, and replacement criteria

Embodied carbon was measured and recorded to support The Portman Estate’s One Planet Action Plan, achieving carbon neutrality with minimal offsetting and setting a replicable benchmark for future workplace retrofits.
