The Treehouse, a biophilic passive solar home in East Fremantle, Perth, designed by Studio Origami

Passive Solar Home · East Fremantle, Perth WAThe
Treehouse.

A mid-century inspired family home among the trees, with views to the ocean, river and port. Designed around an established garden and a bridge-like spine that makes every movement through the house an experience of nature.

Project overview

Living among the trees,
above the river.

The Treehouse is a mid-century inspired passive solar home in East Fremantle, designed to dissolve the boundaries between inside and out: between the tree canopy and the living room, and between the ocean views and the daily rituals of family life. Set on an 890 m² block with a beautiful established garden, the home treats its setting as its greatest asset.

Like the bridges that link the platforms of a treehouse, the main spine of the home connects the north and south decks, day and night spaces, and the upper and lower levels. The result is a home that feels like an adventure to live in, while staying deeply grounded in its landscape.

The design

A bridge between
inside and out.

Inspired by the treehouse: platforms, bridges and canopy views that make every movement through the home an experience of nature.

The site already had a beautiful established garden. Rather than treating it as a backdrop, the design makes it the centrepiece. Working with the existing levels, the home reconnects to the lower garden through generous glazing, direct access and views to the tree canopy from every key living space.

The main spine connects the north and south decks, linking day and night zones while keeping views to the ocean and river. From the upper levels, the Fremantle port and Swan River form a backdrop that changes with the light through the day.

"A home that feels like an adventure to live in: platforms, views and canopy that make every room a new discovery."

The mid-century design language of horizontal lines, generous overhangs and natural materials feels at home in East Fremantle's characterful streets. Passive solar principles work quietly in the background, keeping the home comfortable through Perth's seasons.
