When it comes to designing and building sustainable homes, sometimes the best (and greenest) way forward is to refurbish an existing structure. So when it came time for Australian architect Ben Callery to design an environmentally friendly home for his growing family, he and his wife Brigitte chose to purchase a fixer-upper from a friend’s father, with the intention of retrofitting the existing front rooms, while adding and transforming the rear of the house and property into a cozy, secluded “nest” that would welcome in the sun and outdoor breezes.
Located in Northcote, a quiet inner suburb of Australia’s second-largest city, Melbourne, the original house was a rabbit’s warren of dark, tired rooms, leading to an oversized garage and various lean-tos in the rear yard that served as laundry and bathroom.
Over the following year, Callery, along with family and friends, worked on renovating the property, adding a timber-clad addition in the back, while revamping the three front rooms to be more thermally sound.
By reorienting one of the rooms as a lounge, Callery was able to insert a new bathroom and laundry room in the middle of the house, while the other two front rooms function as two bedrooms.
The rear half of the house is laid out in an open plan concept, which includes the typical components of a kitchen, dining, and living room.
However, to strengthen that all-important connection to the outdoors, the kitchen has been placed at the very rear of the house, which features large, glazed patio doors that fold completely to open up to the wood-slatted terrace and generous backyard.
Says Callery:
In addition, to heighten that sense of airiness, the rear addition features an open double-height space that has been carefully oriented to maximize solar gain and natural cross-ventilation.
Above this airy space is a home office space that wrapped in timber slats, giving the impression that it is a floating nest of sorts overlooking the main common areas. It’s the perfect place for Callery to work, or for his two young daughters to do their homework. Says Callery:
Besides the careful planning of the interior spaces, the design deliberately makes good use of recycled wood. Victorian ash flooring from the existing house was salvaged and transformed into a new vanity unit. Old wooden beams from Callery’s old neighbors’ home were reused. Any timber that wasn’t recycled was locally sourced from mills that offered low-wastage techniques, like radially sawn hardwoods, as well as “seconds” from the reject pile.
As Callery explains:
As this project shows, there’s more than one way to build a greener home, and sometimes, that might mean adapting an older structure—and all the pre-existing embodied energy and embodied carbon it entails—that is already there.
