First UK Commercial Building to Achieve the Top Three Wellbeing Certifications 
16 August 2022

Bloom Clerkenwell has become the first commercial building in the UK to achieve the highest accreditations for wellbeing, sustainability and digital connectivity.

International workspace provider HB Reavis’ building was awarded WELL Certified Platinum in June 2022 and BREEAM Outstanding in May 2022, having achieved WiredScore Platinum in 2019. This makes it the first commercial building in the UK to achieve all three of the top certifications.

Gabriela Guizzo, Project Director at Bloom said: “From the moment we started Bloom Clerkenwell, we knew we wanted to deliver an outstanding workspace, creating a sustainable environment that supports and nurtures people, giving them everything they need to work and feel their best.  

“By targeting the highest level of accreditations, our industry can have a positive impact on the world we leave for our grandchildren. We wanted to push the limits in setting the benchmark for commercial buildings”.

BREEAM Outstanding


Fewer than 1 per cent of new, non-domestic buildings in the UK have achieved BREEAM Outstanding, the industry standard that evaluates a building’s sustainability performance. To do so, a building must achieve a minimum score of 85 per cent in the assessment which is carried out by independent licensed assessors.  Bloom Clerkenwell scored 90.63 per cent.

A central feature that led to the accreditation is Bloom’s encouragement of sustainable commuting and active lifestyles. It features bookable Brompton bicycles to attend external meetings and the ability to cycle straight in from the Cycle Superhighway. It also has 248 secure cycle spaces at street level within the building.


WELL Platinum


Features that helped HB Reavis achieve the WELL Platinum (Core & Shell) certification include:


  • Approximately 11 per cent of the building comprises landscaped terraces (15,400 sq ft), meaning Bloom has one of the highest office-to-terrace ratios of any building in London, offering year-round access to the outdoors. The communal edible garden grows fruit and herbs and creates a space that allows people to relax and manage stress.
  • Bloom is home to a multi-purpose fitness studio (1,200 sq ft) with equipment for classes and individual use. With no membership fees for employees working within the building, the studio is another option for space to unwind and stay healthy.
  • The building has been designed to include architectural features and artwork that enhance the user experience, and technology to ensure the highest standards of air and acoustic quality.

Ann Marie Aguilar, Senior Vice President EMEA, International WELL Building Institute said:

“With its platinum level WELL Certification, Bloom Clerkenwell has shown a commitment to advancing human health and wellbeing in built infrastructure at the highest level. We’re so excited to see their commitment across these accreditations, a first in the region.”


WiredScore Platinum Certification


Bloom Clerkenwell has also secured a WiredScore Platinum certification, demonstrating it is fully tech-enabled, providing resilient and reliable connectivity. The office community is supported by HB Reavis’ smart workspace technology, as part of the building app.

The app used smart technology to allow occupiers to manage their indoor working environment with access to real-time data, such as indoor air quality and space utilisation. The app also facilitates touch-free arrival and concierge services for occupiers. A robust WiFi network has been set up throughout the building to ensure seamless digital connectivity, whether in a meeting room, on the move in a lift, or a communal area.
