designing for people and productivity
Fit‑out specialists Tétris Design x Build recognised that noise control is essential to both comfort and productivity. Uncontrolled noise can increase stress and distract staff, undermining collaboration and focus. To support a hybrid working environment where people can work together and independently without strain, they specified SonaSpray K‑13 Special from Oscar Acoustics throughout the open plan offices.
By absorbing sound energy, SonaSpray delivers clear speech intelligibility and keeps background noise in check, all while seamlessly following the natural lines of the architecture so designers aren’t constrained by rigid conventional panel or tile systems.

safe and sustainable acoustics
Beyond acoustic performance, fire safety was a non‑negotiable priority. Tétris chose SonaSpray because it carries third‑party fire ratings that exceed the latest requirements Class 0 to BS476 and B‑s1, d0, producing minimal smoke and virtually no droplets in the unlikely event of a fire.
As part of one of the UK’s most sustainable buildings, the acoustic strategy also had to support environmental goals. SonaSpray contributes to low‑emitting materials standards and carries credentials such as GREENGUARD Gold and M1 classification – helping the fit‑out meet stringent air quality and sustainability benchmarks and achieve BREEAM excellent.

healthy spaces – proven performance
The completed space now features:
Flexible zones that support focus work and collaboration
Clear communication without raised voices
Acoustic comfort that enhances staff wellbeing
The building also satisfies many elements of the WELL Building Standard and has been rated excellent by BREEAM, demonstrating how strategic acoustic design contributes to broader sustainability outcomes.
