Topped with green roofs and surrounded by walls of glass, the Beach Front Gardens homes in Costa Rica were designed by Tamarindo-based architectural firm Laboratory Sustaining Design (LSD) to embrace the coastal landscape. The complex, which spans a little over 8,000 square feet, comprises two homes — Casa Sare and Casa Caracali — on beachfront property in an exclusive area of the Nicoya Peninsula facing the Pacific Ocean. Approximately 65 percent of the roof surfaces are covered with vegetation to blend the building into the surroundings and to help reduce energy demands for cooling.

To minimize maintenance and ensure structural longevity, the architects designed Casa Sare and Casa Caracali with durable materials and finishes to withstand the corrosive powers of the ocean air and harsh tropical elements. The flat, turf-topped roofs also include long overhangs to protect the interiors from unwanted solar gain. The desire to blend both homes into the environment drove the design of simple architectural shapes, a minimalist material palette and walls of operable glass that open up to completely blur the boundaries between indoor and outdoor living.

“Each house was designed for users to experience the tropical weather and beautiful nature, and every single space of both houses has a great relation with the exterior, bringing in the natural light to all the interior areas and looking for cross ventilation using the sea breeze year-round,” the architects explained. “Around 65 percent of the interior areas are covered by green roofs, reducing the footprint of the project in this protected environment.”

Organized into a V-shaped layout, Casa Sare was placed closest to the beach on the flattest part of the property. The private areas are separated from the communal areas with an exterior terrace accessible from all rooms. In contrast, Casa Caracali was placed on higher elevation and is segmented to step down on the slightly sloped terrain. The social areas are located near the rear at the higher elevations to take advantage of ocean views, while the bedrooms are placed closer to the beach.
