HUSH acted as project manager and contract administrator, responsible for enhancing GPE’s existing asset at 45 Mortimer Street delivering a scope of occupier amenity improvement works including the Cat A fit-out of a vacant floor, upgraded end of trip facilities, creating a new outside ground floor terrace facility from a previously unutilised external space and new reception facilities with smart technology upgrades.  ​​

The project brief and design ethos focussed on re-use, retaining the existing raised floor and reception finishes. Brilliant interior design provided by Conran effortlessly mixed re-used stone and timber with new materials to transform the previous lifeless reception to provide a welcoming and inviting entrance together with new collaboration and working zones including new coffee facilities. The new 3rd Floor Cat A has achieved SKA Gold rating and is WELL enabled.  ​​

To support GPE’s smart building technology, lift destination control works were implemented to the existing lifts which streamlined security and access throughout the building.   ​​

Managing the construction phasing and sequencing to implement the works whilst the building remained occupied through-out and maintaining access through the existing entrance were the challenges HUSH overcame to deliver an exceptional project.
