Kailua Hale

This 1,000-square-foot, two-bedroom, two-bath home in Northeast Maui exemplifies thoughtful design that maximizes sustainability and comfort. Including a small carport and storage, the total under-roof area is approximately 1,500–1,600 square feet. Despite its compact size, the home feels expansive due to its seamless integration with 180-degree ocean views. The design incorporates both passive and active solar strategies, featuring photovoltaic (PV) panels, solar hot water systems, and strategic orientation to balance energy efficiency with stunning vistas.

The roof design harmonizes aesthetics, functionality, and cost-effectiveness. A carefully adjusted ridge line supports active solar systems without resorting to complex forms. East-facing panels generate power early in the day, while west-facing panels extend energy availability into the evening, addressing site-specific challenges of solar gain and energy generation. High ceilings, elongated layouts, and expansive openings enhance the perception of space, framing the natural beauty of Hawaii while maintaining a welcoming and airy atmosphere.

Natural ventilation is key to the home’s comfort, reducing the need for air conditioning. Aligned with prevailing winds, large openings and clerestory windows maximize airflow, ensuring a cool environment year-round. Additional design features, such as overhangs, diffuse natural light while preventing heat gain, creating a shaded, bright interior that minimizes issues like mold and moisture. These elements demonstrate how compact tropical homes can combine aesthetics and functionality with environmental responsiveness.

The home’s off-grid systems further highlight its sustainable approach. A rainwater catchment system collects and stores water in a 15,000-gallon tank, providing a reliable supply even in dry periods. The roof, spanning 1,600–1,700 square feet, is optimized for both rainwater collection and energy generation, with a 10,000-watt PV array capturing sunlight from early morning to late afternoon. Together with a polished concrete slab acting as a thermal mass and precisely calculated shadow angles, the design integrates passive and active solar strategies to achieve an efficient, self-sustaining, and comfortable living environment.
