The Turnbull Building was acquired by Northern Land in 1999 and converted to residential apartments for sale. The central bay of the building was taken out and a full height five-storey atrium created with lift access, stairs and bridges across the void into some of the apartments.

Thirty nine apartments around the perimeter vary from one bedroomed studios at approximately 550 ft sq, to two bedroomed units at approximately 1000 ft sq on
the first to fourth floors.

The fifth and sixth floors have eight penthouses which are duplex in plan - access into the fifth floor which contains the bedrooms and bathrooms and a staircase up to the living spaces on the sixth floor. Some of the penthouses have external terraces and two include the cavernous tower spaces.
