Project Profile 

The conversion of a three storey public house dating from the early 1840’s to a four storey office accommodation, located in the Holland Park West London.

This required careful co-ordination of both the Mechanical and Electrical services to ensure that the office spaces can Comms room were served to the required standard while maintaining the residential character of the space.

The energy efficiency of the building was greatly improved while still maintaining the external appearance and features of the property. The Engineering services solution featured the installation of Air to water heat pump system, air conditioning and photovoltaic solar panels.
