This project is a redevelopment of an existing workshop building at 21 Martin Square, into a modern open-plan head office space for First Principles Constructors.






The project involves a total strip-out to bare bones, construction of a new concrete mezzanine floor, new roof structure and insulated roof
with skylights and clerestory windows; new aluminium window and door joinery, and a façade refresh.
The interior works include construction and fitout of new offices, a feature stair, meeting rooms, a boardroom, a kitchen, and a gym. With
no ceilings and a mix of new and old structural elements on display, this project features multiple exposed finishes and services, alongside
feature wall linings and floor finishes, creating an exciting working environment with a distinctly industrial vibe. All new electrical,
mechanical, plumbing, and fire services will be installed, including a new sprinkler system.
