Premier Technical Services Group Ltd (PTSG) has been contracted to deliver specialist fire solutions at Cambridge House in central London. 

Cambridge House is a Grade I listed former townhouse. It sits on the northern side of Piccadilly at number 94, in the fashionable district of Mayfair. As of 2021, the property is being converted into a luxury hotel and seven residences. The house was built in 1756–1761 by Charles Wyndham, 2nd Earl of Egremont (1710–1763).  

In April 2013, David and Simon Reuben received approval to develop the property into a 60,600 square foot single home. It would likely have become the UK’s most expensive home, estimated to be worth about £250 million after renovation. According to Bloomberg News, “the planning application for Number 94 was approved after the two investors offered to contribute £3.85 million to the construction of affordable housing in the borough.”  

However, that development plan subsequently changed, and a new plan was conceived to convert the property into the “Cambridge House Hotel and Residences”, with a five-star hotel and seven serviced residences.
