Reference projects
Cooks River House is located in Sydney's inner west and sits on a sloping site facing south along the Cooks River. The original single-story bungalow with an unsympathetic later addition was removed to reveal the original form, creating light-filled, open living spaces that better connect to the surrounding garden. The key intentions of the project were to improve the connection to the natural beauty of the site and to respond to views, topography, and light. As part of the project, Warema External Venetian Blinds in Anthrazit Eisen were incorporated. The blinds, in combination with Reynolux EcoClean, enhance their performance, likely improving their effectiveness in managing light and heat while contributing to energy efficiency. The blinds allow external views while controlling natural light intensity with adjustable slats, significantly lowering daytime lighting costs. The shade factor provided by these external Venetian blinds allows for better control of sunlight entering the space, making them an essential component of the overall design.
The site of the House at Otago Bay is characterized by a layer of topsoil that supports grasses, native plants, and sheoaks near the water, along with larger gums at the top of the block. It slopes steeply towards the river and a freshwater lagoon to the north, with the western boundary marked by the Derwent River's high water mark. The colonnade's depth is influenced by sun angles to exclude the summer sun while allowing the winter sun to warm the slab. The building features thermal mass, insulation, and double glazing to maintain stable temperatures year-round. Programmable external venetians are used to address the conflict between Western views and sunlight. Cross ventilation and active night purging utilize evening breezes to lower slab temperatures, with stored coolth serving as the sole air conditioning needed.
The Beyond House project aimed to transform a dark, cold, and narrow heritage house into a naturally comfortable and sustainable home for a family of three. The design focused on integrating the indoor and outdoor environments, maximizing sunlight and breezes, and incorporating sustainable features such as solar power, water harvesting, and recycled materials. The addition of a central void, external louvers, Venetian blinds for sun control, and a roof deck allowed for social connections, passive design, and a productive garden. The owners' strong social connections in the neighborhood influenced the design, and the focus on sustainability extended to both high-tech and low-tech solutions throughout the architecture.
