Casa Carazo

Casa Carazo

EDGE Advanced

Carazo Arquitectura, an architecture firm in Costa Rica that focuses on sustainable design, is opening a new office in San José. Located in the center of the city, the new office can be accessed by public transportation and bicycle. The office, Casa Carazo, is a reflection on the future of workspaces and showcases the firm’s focus on creating healthier, happier, and eco-friendly spaces.

Casa Carazo is both a restoration and a new building project on historic property. For Carazo Arquitectura, the reutilization and revitalization of disregarded urban centers are opportunities to integrate nature and create new ways to live, experience, and understand the capital city.

An energy-efficient cooling system, external shading devices, water-efficient plumbing fixtures, and more will be installed to reduce the office’s energy and water usage. A green roof will also contribute to energy savings. When possible, the existing floor, roof, walls, and window frames will be re-used to reduce the project’s embodied energy in materials.

Casa Carazo has received an EDGE Advanced certificate from the Green Building Council Costa Rica.
