Arup is working on a state of the art office development for developer British Land Company PLC, who has secured one of the largest West End pre-lets in over 20 years on the project. 

The design is an exemplar piece of integrated architecture and engineering. The multi-disciplinary team have challenged the status quo of conventional refurbishments to deliver an environmentally responsible, socially active building for its 3,500 users. 

All design services are being provided by our architects’, engineers’ and specialists who co-locate as a single, design focused team. This unique way of working together, with a mutual ambition to optimise and innovate, has delivered significant additional value for our longstanding client.  

The project started on site in March 2018 and is scheduled to complete in December 2020.

Continuity of design

We designed the original building during the 1990’s and were invited back by British Land to refurbish 1 Triton Square with continued authorship. This led to a proposal which evolved but complimented the original concept by reiterating the corner core placement; celebrating the floating façade screens as a primary part of each elevation; meticulous attention to interfaces between materials and consistency of proportion across all scales.

Consideration was given at the outset to maximising retention of both the existing structure and building fabric. This combined with reuse of the building’s corner core’s assists to greatly reduce embodied carbon during construction and throughout the service life of the building.

A building for people

1 Triton Square will become a healthy workplace for 3,500 people with exceptional amenity, daylight and social connectivity. The atrium and new structure has been designed to incorporate satellite atria, breakout space and stairs between floors to encourage walking and visibility. Five generous terraces are provided at level six which will have a variety of uses from rest and contemplation to events and sporting activities. Cycling to work is greatly encouraged by the integration of over 500 spaces inside the building at ground floor level

Digital value

Arup’s multidisciplinary proposals for 1 Triton Square have been designed in a real-time BIM environment where multiple models overlay and evolve together as the co-located team develop the design. We use a wide range of parametric digital tools to streamline the design process and maximise time spent effectively. This adds significant value to our service and ensures a higher quality, optimised product at the end of each stage. 

We use our virtual reality station to visualise and solve challenges on a daily basis. The team including the client, tenant and contractor find this particularly useful to rapidly understand a space or topic of debate.

Moving forwards, we are working closely with the Contractor to ensure the project benefits from the very best that digital design and coordination can offer during both procurement and construction.
