Scalable Fire Suppression for a Modern Residential Scheme
NPHS delivered a discreet, high-performance water mist fire suppression solution at 44 Portland Place, an ultra-prime residential property in Marylebone that underwent an extensive, design-led refurbishment. Appointed by CCP HVAC, the brief demanded absolute reliability, minimal visual impact, and full alignment with modern fire-safety expectations for a single, high-value dwelling.
The installation comprised four dedicated pumps feeding 82 precision-engineered mist nozzles, providing fast-acting suppression while dramatically reducing water usage and secondary damage compared to traditional sprinkler systems. The system was carefully integrated into the fabric of the building to preserve architectural detailing and interior finishes, a critical requirement for a residence of this calibre.
Designed to protect life, structure, and irreplaceable interiors, the solution balances performance with discretion, making it ideally suited to prime residential environments where aesthetics and protection must coexist. The project stands as a strong example of NPHS’s capability to tailor advanced fire suppression systems for bespoke, one-off properties in London’s most prestigious postcodes.
The property has been widely recognised within the prime residential sector, including coverage by PrimeResi, reinforcing the level of quality and specification required on this project.
