*** WINNER *** Deloitte, 1 New Street Square - submitted by Overbury

1 New Street Square is a workplace that benefits people and the planet. Their office scored a record 94%, exceeding the ‘Outstanding’ threshold and becoming the highest scoring BREEAM 2014 Refurbishment & Fit-out project in the world. The office also attained WELL Certified™ Gold and in securing this, became both the largest WELL Certified™ Gold for ‘New and Existing Interiors’ project in the world; and the first BREEAM Outstanding/ WELL Gold dual-certified office fit-out in the world.

With this project, they are showing how environmental sustainability and user-centric design can go hand-in-hand in an innovative yet replicable manner. Taking on a base-build that peaked with BREEAM Excellent and had no wellbeing considerations of note could have been a constraint, but through early engagement, thoughtful design and collaborative partnerships they achieved something special.

For them to feel the project is successful, they want to use it as a catalyst for positive change. To this end, they recently hosted BCO and CoreNet seminars to share their experiences of delivering an efficient, healthy workplace. They have also created press releases, created a microsite, shared case studies (and encouraged the same of their partners), held internal seminars and are promoting this agenda across their 250,000+ Deloitte Global network. 


  • Their environmental agenda delivered the highest BREEAM 2014 Refurbishment & Fit-Out score ever achieved at 94%
  • Their wellbeing strategy ensured 1 New Street Square became the largest WELL Gold certified commercial interior worldwide
  • Delivering both in parallel meant they became the first office fit-out to attain BREEAM Outstanding/ WELL Gold worldwide
