Guided tours

The Annex, a tropical treehouse in the City.

Modest by name but ambitious by design, The Annex sits nestled amid Brisbane’s iconic Eagle Street fig trees. It’s also the home of the BVN Brisbane studio.

Leafy Inspiration
Every detail of the building is designed to connect with the adjacent fig trees, including the sense of ‘being under the canopy’, and ‘looking through the foliage’. Visible from each level of The Annex, the trees are ever-present through long views down the street, and lovingly imbued in the architectural detailing. Glass ‘fretwork’ offers privacy and mimics the shifting patterns of the leaves.

Life in the Fig Tree Grove
A new public place has been created under the canopy of the overhead form – extending through to the remade plaza of the existing Blue Tower and the laneway adjacent to the historic building Corbett Chambers. Oriented towards the fig tree grove; this lively space connects and enhances Brisbane’s pedestrian network.

A series of terraces, landscapes and public seating, as well as dining and entertainment, promote social activity and outdoor gatherings. Back-lit laser-cut panels glitter over these spaces, evoking the sensation of dappled sunlight beneath the fig trees.

BVN’s Very Own Treehouse
BVN has endorsed The Annex with its own tenancy, relocating the Brisbane studio in 2021 into Levels 3 and 4. It’s a joyful, leafy, sunlit space that invites collaboration, while maintaining malleable spaces for focused work against the backdrop of majestic fig trees. Bathed in sunlight, surrounded by greenery and entwined with nature, The Annex is a city pad and tropical treehouse perfectly suited to Brisbane’s sub-tropical CBD.
