Lendlease has lodged a planning application for yet another engineered timber office building at Sydney's Barangaroo South.

The seven-storey building proposed has been positioned as the ‘sister building’ of the Tzannes-designed International House Sydney, an office built entirely of cross-laminated timber (CLT) and glue-laminated timber (Glulam).

This second building, also designed by Tzannes, would be constructed of the same materials – for instance, concrete, charcoal face bricks and a glass fa├žade.

The design application proposes 726 square metres of retail shops on the ground floor, and 11,022 square metres of commercial space spread out across levels one to six.

According to the proposal, the structure has been designed in two parts. A two-storey base includes the colonnade and responds to the scale of the public environment, while the unified, upper five-storey form has been expressed as a “clean, simple glazed envelope”. This allows the interior timber elements to be visible from the outside and celebrated as the “hero” of the design.

Other features of the proposed building include an outdoor terrace on level six, solar panels on the roof, and 18 car spaces and 35 bicycle spots within the basement level.

The building will be located on Hickson Road in front of Tower 1 of the Rogers Stirk Harbour + Partners-designed International Towers Sydney.

The plans are currently on exhibition for community consultation. Submissions can be made until Friday 8 December. More information here.
