Rathbone Square : full digital project

A successful complex digital project onsite

Project Overview

Rathbone Square was Great Portland Estate’s largest single development to date. It was also central London’s first new large public square in a century. The programme demanded exceptional perfomance and utilised digital technologies widely onsite during design and installation. TClarke were selected to play a major role with main contractor Lendlease in bringing the project to a successful conclusion.


“Over 3 years, with our partners, we've delivered Rathbone Square as an effective digital project from start to finish.”
