Following a twofold brief, Alexander Symes Architect created an office space, guest house and entertainment area with recycled and renewable materials that echo the ethos of likeminded sustainable buildings. Extending the family home over a slopping landscape and around a tree protection zone, both architect and builder worked cohesively with each other to reflect the positive aspects of sustainable design. What transpired from this effort was an office space, living area, kitchen and guest living space that wrap around the home’s namesake, the pepper tree.

Covered by the canopy of the pepper tree, the garden was transformed, seeing hand-poured pavers lead guests up towards the passive house. Evidence of the passive house concept is also seen at the home’s entrance; wood and convict bricks are used similarly throughout the interior design, seeing sustainable living enhanced through natural thermal heating and cooling. Due to its north-facing position, the convict bricks add a thermal structure throughout, soaking up the natural heat of the sun, whilst the shade of the canopy does the same in the warmer months.

From planning to building to completion, Pepper Tree Passive House passionately showcases the skillset required for sustainable living, alongside Souter Built’s philosophy for sustainable building. Through the architecture and design choices, guests and clients alike can see firsthand how using recycled materials, instead of depleting natural resources, can leave a better footprint for the future of sustainable buildings.
