20 Martin Place


Download Project Sheet

The client brief demanded a comprehensive refurbishment feasibility study of an existing 1960s office building located on Martin Place in the heart of Sydney’s CBD.

Considered a prime asset in an owner’s portfolio, the Building Studio proposal completely reimagined the building by transforming it into a modern Grade A office tower, stripping back the original facade to raw structure and re-cladding it with a new high performance, sheer glass curtain wall facade.

Unusually for a building in Sydney, 20 Martin Place is constructed with a steel framed primary structure, allowing the original internalised central core to be entirely removed and relocated to the northern boundary, thus releasing additional net lettable space with a dramatic increase in the building’s spatial efficiency. The 1200m2 floor plates are unencumbered, allowing universal flexibility for future tenancies.

Basement floors have been converted to restaurants, cafes and bars and the main entry lobby has been completely refurbished to provide a multi height volume befitting this Grade A development. A new through-site link has also been established at the ground floor connecting Martin Place with the network of intimate laneways hidden in the city.
