It’s better by barge

The journey towards making a greener workspace started on the water.
We became the first office building in London to transport construction materials by barge. And that’s just one example of the sustainable thinking throughout the building.

Built different

Drawing from yesterday to protect tomorrow, embodied carbon was reduced by retaining 70% of the original building.

Sustainability in action

The Delft is designed to think ahead. Its smart systems understand how people use and move through the building, using real-time data to optimise energy, comfort and performance. The result is a more responsive workplace that supports wellbeing, reduces waste and anticipates maintenance needs before problems arise.
