Their shade cooled the site, and their canopies defined pockets of light and shelter. Rather than approaching the space as a blank canvas, Jed Long began the design of Legombang Treehouse by determining what should remain, allowing the existing landscape to guide every decision that followed. Long before it became a design concept, a treehouse was something many of us imagined as children, and the project draws on that same sense of curiosity.

Conceived as a home for his own family on Bali's southeast coast in Pantai Lembeng, the home became an opportunity to test ideas that have long shaped Cave Urban's practice. Instead of imposing a new order onto the site, the existing mature trees became the organizing framework for the build, informing the placement of rooms, circulation paths and open spaces. The result is a treehouse that sits comfortably within its verdant landscape, where architecture and nature exist as one continuous experience rather than as separate elements.

The land already knew the way.

The relationship between home and environment continues through the planning of Legombang Treehouse. The spatial organization reinterprets the nine-square geometry of Asta Kosala Kosali, the traditional Balinese system of spatial planning, arranging gardens, living spaces and circulation across two levels beneath a single roof.

Bauhaus Earth engaged Eco-Mantra to conduct a Whole Building Life Cycle Assessment (LCA) demonstrating a 110% reduction in Stage A carbon emissions compared to a conventional baseline building. While a standard equivalent structure would emit 59,722 kgCO2e into the atmosphere, BaleBio achieved a climate-positive, carbon-negative footprint of -5,907 kgCO2e. This reduction was driven primarily by the pavilion's production stage (A1–A3), where engineered bamboo successfully sequesters carbon, alongside optimized local transport (A4) and construction.

“Designing your own home is a rare opportunity. It strips away trends and expectations, leaving only the question of how you truly want to live. For me, that meant letting the landscape lead, drawing from Balinese knowledge, and creating a home that feels like it belongs exactly where it stands.”
