Dicen que el escritorio de una persona habla mucho de su personalidad... y en nuestra oficina, ¡hablan bastante! 🤭

🕵️‍♂️ Fuimos a explorar los espacios del equipo y encontramos estos tesoros (y algunas rarezas). Hay de todo: diseño puro, caos creativo y cosas que simplemente no sabemos cómo llegaron ahí.

Cuéntanos, ¿con cuál de todos te identificas más? 🤔 ¿O acaso tienes algo aún más raro en el tuyo? Te leemos. 🔍👀👇

CHICK-FIL-A, PLAZA CENTRO (2026)

When culture becomes space? To honor the client's vision of incorporating elements of Puerto Rican culture, we designed an outdoor dining experience anchored by custom, board-formed concrete planters and decorative precast panels, introducing warmth, texture, and visual depth. The landscaping further reinforces this vision, embracing a more tropical aesthetic that reflects the local context.

RSM (2022)

RCMDO reimagined RSM Puerto Rico’s 22,000 SF San Juan office as a modern, dynamic workplace that supports growth and evolving workstyles. Within the existing two-story structure, the design increases private offices and enhances spatial efficiency.

An expansion into a former parking area introduces a new lounge, cafeteria, and conference room. Custom cementitious wood fiber baffles create acoustic comfort while framing original arched windows.
Strategic interventions—including a steel beam and glass partition—bring openness and transparency, while brand-driven finishes add vibrancy.

The result: a contemporary interior in dialogue with its 1950s Spanish-Mediterranean exterior.

CASITA ROSADA - Cayey Biodiversity Center (2026)

The restoration of the Casita Rosada into the Cayey Biodiversity Center reimagines architecture as an active participant in the local ecosystem. By integrating native flora to support pollinators like hummingbirds and butterflies, the design creates a reciprocal relationship between the built environment and indigenous fauna.

The intervention transforms the entire structure, turning the rooftop into a walkable green habitat and elevated walkway for public learning. A new annex volume follows this same conceptual logic, serving as a multipurpose auditorium for cultural and municipal events. Together, these elements form a cohesive architectural refuge that functions as both a living habitat and a vital educational platform for the community.

AON Reception (2020)

This redesigned space introduces a compact, welcoming reception, wrapped in a sculptural glass enclosure that sets a refined tone on arrival. Beyond the entry, the layout unfolds into new collaborative zones, a dedicated wellness room, a private office, and an upgraded break room—all while reducing the overall tenant footprint. The result is a streamlined, modern environment that balances comfort, productivity, and thoughtful use of space.

FEMA’s CRC ATLANTIC (2018)

Commissioned as part of the integral design for the main lobby of FEMA’s CRC Atlantic in Guaynabo, Puerto Rico, both the lobby environment and its featured lamp were conceived as a unified design gesture. The piece responds to a broader conceptual strategy centered on reinterpreting elements of the local landscape and culture. In this case, the “racimo de plátano” is adopted as a native symbol, evoking resilience, rootedness, and sustenance—values closely aligned with FEMA’s role on the island.

More than a standalone fixture, the lamp functions as an integral installation within the lobby, weaving together identity, function, and poetics to shape a cohesive and meaningful arrival experience.

CASE STUDY: CABIN-01

Our latest case study, is conceived as an exploration focused on the development of a modular countryside dwelling, addressing the challenges inherent to modular design and prefabrication while maintaining a constant openness and connection to the surrounding natural landscape. The project investigates the integration of materials such as concrete, wood, glass, and natural stone cladding, used as finishing elements to achieve a restrained architectural expression.

The proposal is organized around a cross-shaped floor plan, supported by a cantilevered structural system that minimizes the footprint on the site. This configuration enables the creation of open and fluid spaces, complemented by generous cantilevered overhangs that strategically frame views toward the surroundings, reinforcing the visual and spatial relationship with the natural landscape.
