The development of Pepper Tree Passive Home by Alexander Symes Architect started quite a few decades back in collaboration with builder and shopper Adam Souter of Souter Developed, who lives on the home with partner Ame Rooke-Jones, and their three young little ones.
The family’s Wollongong house was weary and thermally inefficient, but functionally suitable. In its place of expending their price range on sizeable upgrades to the present dwelling, they resolved to establish a new, different construction on the rear of the web site to a Passive Household standard.
‘This meant they would get the very best amenity value for their funds with slight performance dependent updates to the present residence together with new insulation, cladding, repainting the concrete tiles a lighter color to cut down heat obtain, and a 12kW photo voltaic panel awning that gives shade to the out of doors spaces in summer time,’ suggests Alexander Symes, director of Alexander Symes Architect.
Just after the first strategy was produced, Adam commenced salvaging and storing landfill-certain elements from his other construction assignments to eventually use in his house.
The ensuing secondary dwelling takes the form of an elevated U-formed setting up wrapping all over an present 60-12 months-previous tree.
‘We made the decision at our original conference that the pepper tree was section of the main identity of the site and preserving it would be a fantastic profit to the remaining end result, instead than just a further box-shaped granny flat,’ says Alexander.
Two cantilevered wings are clad with recycled shou sugi ban cladding, and every single host a green roof blending the building into the landscape.
Adam’s salvaged construction supplies were being used in the course of the job, which include on the external staircase built making use of the roof framework of a demolished Bondi house, contributing to its sustainable Passive House regular.
The finished self-contained household incorporates one particular bedroom, a kitchen, residing region, bathroom, and a laundry across 60 square metres internally. The creating functions as an workplace for Adam’s growing firm, which can alternatively be rented as limited keep accommodation.
In designing a secondary framework, Alexander Symes Architect have extra a lot needed usable floor space to a suburban web site with out overdeveloping or sacrificing its biophilic connection. This approach supplies a precedent for making compact, potential proofed additions with no the huge charge of upgrading all existing dwellings.
