88 Angel Street by Steele Associates Architects seamlessly integrates optimal low-energy building design with stylish and comfortable spaces.
The three-terrace development is proof of the commercial viability of residential buildings designed using cutting-edge technologies with sustainability as the central goal. The ubiquitous green roofs which cloak the buildings are just the tip of the iceberg of an environmentally conscious construction in which the subtle elements are equally impressive from a design standpoint.
The challenges were mostly how to put together a package of features that would make the house environmentally sustainable, aesthetically pleasing and comfortable to live in while keeping construction and eventual maintenance costs viable.
Throughout the entire project since conception, each aspect has been researched, modelled, tested and finally selected to ensure that it is the best available to craft a highly-efficient, highly-liveable home. The building materials have been sourced to ensure minimum environmental impact.
The spatial arrangement is driven by passive solar design principles. Stack-effect ventilation expels summer air through the open, shaded glass roof when automatically opened by thermostat control. All rooms have windows that ventilate while maintaining weather-tightness and security. This design for cross-ventilation creates perceptible breezes in all habitable rooms.
In winter, the glass roofed courtyard is closed, and the shade louvres automatically tilt to admit and trap the sun’s warmth. A 600mm Bioethanol fireplace is enough to comfortably heat the kitchen, living and dining spaces. The glass wall separating kitchen and courtyard with a pivot door is intended to be closed on winter evenings, keeping the fire’s warmth in the living space. Opening the door allows the heat to permeate the sleeping levels at bedtime.

“The more we read about this project, the more it just kept on giving and giving. From its Envirocrete slab and carpets made from recycled PET, to its massive green roof and huge solar array, the environmental footprint of this building has been deeply considered from top to bottom.
“The building’s commercial success is owing to the architect’s commitment to delivering a premium product without compromising on best practice sustainable building and material procurement. It provides a sense of optimism to the industry by demonstrating that real sustainability can compete in the market with the status quo and be an integral part of commercially-successful developments.
“Sydney needs more and more of these projects if it is to keep up with the types of developments going on in Melbourne.”
