Tree Apartment

Crafted by nature, ‘Tree Apartment’ echoes the scale, proportion and materiality of the nearby London Plane Tree

Calibre is an 8-story boutique residential apartment in Sydney’s Surry Hills, comprising 18 apartments.  The design speaks to the natural landscape, becoming an extension of the London Plane tree canopy. The design of the building is a response to the trees which typically shade the streets and terraces beneath, opening up a new dialogue above the tree-tops.

Calibre invites residents to connect with nature, as if living in a Treehouse.

Nature is apparent in every detail of Calibre’s architecture. The light, open and organic form engages with the streetscape, lending itself beautifully to the surrounding context of Surry Hills.

The façade acts both as privacy and security screening. This gentle architectural silhouette maximises sun, letting filtered daylight and natural ventilation throughout the apartments.



The interior design of Calibre also contributes to its design excellence. Every apartment was designed to breathe. The unique façade feature allows residence to achieve an excellent privacy and full height glazing system maximises sun, fresh air and sky views within the tight infill development. Deep balconies with flush finish flooring become an extension of the interiors, amplifying the sense of space, while the selection of neutral colour finishes with natural materiality was designed to maximise daylight in livings and make compact city apartment living feel much more spacious with encouraging an interaction with nature.

Leading lines, luxurious details and tactile appeal, Calibre’s message is one of effortless simplicity. Intelligent planning and floor-to-ceiling glazing really work to bring the outside in. Slatted screening and barely-there glass create both openness and privacy.

Enduringly beautiful interiors are drawn with a true artisan’s eye.

Natural textures and hues make these tranquil apartments supremely restful with generous and elegantly crafted details.

This exquisite and artful building houses an exclusive collection of just 18 beautifully designed residences.
