Wood lattice walls ventilate this beautiful Costa Rica home

Perched in the mountains of Nosara, a surfing paradise on the Nicoya Peninsula of Costa Rica, Casa Guayacán boasts a beautiful ocean view and a tranquil setting.

A stunning example of sustainable architecture in a tropical setting, this home being designed by two talented professional architects comes as no surprise.

Evangelina Quesada and Lucca Spendlingwimmer, architects who moved to the remote mountain location with their two daughters, built the home based on their mutual love for contemporary tropical architecture. The home takes advantage of the ocean breeze with ventilating lattice walls and is equipped with a rooftop solar panel system that provides 100% battery autonomy throughout the day and night.

The facade incorporates a design that combines spacious floor-to-ceiling windows and wood lattice walls for natural cross ventilation. Elongated from north to south, most of the space faces the sea, with the west side facing the sunset in the evening. Half-open wood slats help emphasize airflow, while also creating a unique light pattern that changes during different times of the day.

To move the house as far from the public street as possible and address the site’s uneven terrain, the design was developed over two levels. A shorter lower level allows for entrance access below the main structure, room for parking, a studio and service area. The upper level contains common areas, bedrooms and the property’s best ocean views.

The home’s modular floor plan allowed for a faster construction time and less material waste. The home uses materials such as stone, polished cement, metal, wood and glass. The wood, taken from controlled teak plantations, was treated with linseed oil to maintain natural texture and color. Incorporating traditional building methods and talent from local artisans in the woodwork helps make Casa Guayacán a captivating addition to the tropical Costa Rican foothills.
