This ADU is conceived through the relationship between form, light, and material expression. Two gabled volumes meet at an obtuse angle, generating a curved central space that organizes the interior and creates a dynamic relationship between enclosure and openness. The geometry produces a sequence of compression and release, drawing light deep into the building while establishing views across the interior. Extending outward from the central space, the deck fosters social connectivity between the landscape, the ADU, and the main house on the property. The project’s material palette reinforces this architectural clarity. Structural insulated straw panels define the enclosure as thick, monolithic surfaces, while a granite plinth foundation allows the building to engage the ground lightly and with minimal disturbance to the site. The use of structural steel enables the curved central volume and supports the formal ambition of the roof geometry, introducing a deliberate tension between expressive form and low-carbon construction.

Rather than treating sustainability as an applied strategy, the project integrates environmental performance directly into its architectural language. Form, structure, and material are conceived simultaneously, producing a dwelling that balances spatial richness, structural expression, and material responsibility.
