Riddel Architecture spent five years designing and overseeing the construction of a light-filled, airy and sustainable home in Brisbane, Australia. Centor spoke with architect Emma Scragg about the project.
Tell us a little bit about yourself and your practice.
All our buildings respond to their environment and climate, with lots of indoor-outdoor flow of space. All our architecture aims to respond to the climate and the building’s local environment and setting.
What was the design brief for the Hill End Eco House, and what was your vision for achieving your client’s goal?
We wanted to create an architectural landmark that was contemporary, responded to the climate and responded to the local architectural character. When I came back optimistically with a comprehensive brief of elements that a sustainable house should feature, they said yes to everything.
The building team, Rob Peagram Builders, recycled 80 per cent of the original building and incorporated it into the new building. We wanted it to be a home where you would not need to use air conditioning and had very low embodied energy.
Were there any challenges in trying to achieve your vision for this project?
Since the beginning of the project, there has been a huge change in access to sustainable materials. It’s much easier now than it was five years ago. We did a lot of in-house research because I’m committed to sustainability, and we also used www.ecospecifier.org a lot.
The house has very low embodied energy because the entire frame is recycled hardwood, most of the cladding is recycled, and new products have recycled content.
What atmosphere were you trying to achieve in this building?
Bifolding doors allow for a broader outside-inside transition space than other door types. How important was this for achieving the look and feel of your design?
You also used Centor A6 sliding hardware in this project. Tell me about that.
We used a sliding door in this space for thermal efficiency and for sound. The house is very open plan, but we wanted the option to shut down spaces, so if you wanted to heat the space, you could do it efficiently. The sliding door also makes a lot of sense in tight spaces. While the space looks big, once you put furniture and shelves in, there’s not always room for a big double-hinged door.
Why did you use Centor systems?
