4 Pancras Square is a 10 storey, 174,570 sq ft office development on Pancras Square, one of London’s fastest growing creative hubs, houses Universal Music’s global headquarters with a ground floor café/bar opening to the Square. Notable for its innovative structural weathering steel exoskeleton against a backdrop of white glazed ceramics,
the new build has been awarded the RIBA London Award 2019 and RIBA National Award 2019 and holds a BREEAM Outstanding score of 88.1. The site faces a number of buildings Sandy Brown has provided acoustic design advice on including Google’s 6 Pancras Square, London Borough of Camden’s Five Pancras Square, 3 Pancras Square and offices within 2 Pancras Square.
Similarly to Five Pancras Square, Sandy Brown provided design input for the base-building and Cat A fit-out, including an acoustic performance specification for architectural elements.
Key acoustic requirements included:
• ensuring the facade design was capable of controlling environmental noise ingress to the speculative office floor plates, and flanking transfer was well-controlled
• ensuring the internal sound insulation performances of floors, partitions and doors was appropriate for speculative offices
• control of noise and vibration from building services to be in line with the relevant BREEAM requirements and the planning criteria externally
The impressive structure balances modern architectural standards with Kings Cross’ industrial heritage, resulting in the 2018 BREEAM Award for the best Commercial Project – Post-Construction. Energy efficiency was prioritised in a range of applications including LED lighting, solar shading, thermal mass for cooling and a link to the site-wide district heating network.
In terms of acoustic design, there are two principle elements affecting a building’s BREEAM rating, namely the indoor environmental quality (i.e. the acoustic performance within the building) and noise emissions from the building to the external environment.
