JSARQ: Casa Mad

Completed in 2025 in San José, Costa Rica, Casa Mad by JSARQ is a refined example of contemporary tropical architecture that prioritizes coexistence with the natural environment. Spanning 5,900 square feet, this two-story residence was conceived around three existing trees on the site, a design decision that shaped the spatial configuration and architectural identity of the home.

Rather than imposing itself on the landscape, Casa Mad adapts to it. The project embodies contextual architecture in Costa Rica, where built form and vegetation engage in continuous dialogue.

Designing Around Nature: A Tree-Centered Concept

At the heart of the design lies a simple yet powerful strategy: preserve and celebrate the existing trees. These mature elements become spatial anchors, influencing circulation, courtyard placement, and visual connections. The architecture bends, shifts, and opens itself to accommodate them, demonstrating a sustainable and site-responsive design philosophy.

This approach reinforces biophilic design principles, strengthening the emotional and sensory bond between residents and their environment.

Courtyard Living: Seamless Indoor-Outdoor Integration

Casa Mad unfolds through a layered sequence of internal, lateral, and frontal courtyards, creating a dynamic interplay of light, vegetation, and structure. These open-air spaces dissolve conventional boundaries between interior and exterior, allowing natural ventilation and daylight to permeate the home.

The courtyards function as:

• Climatic regulators in the tropical context
• Visual connectors between rooms
• Private green sanctuaries within the residence

Through this strategy, the house achieves seamless indoor-outdoor living, a hallmark of modern Costa Rican residential architecture.

A Rotated Cantilever: Framing the City

One of the defining architectural gestures is a rotated and cantilevered upper volume that projects toward the landscape. This bold move frames panoramic views of San José while introducing dynamism and sculptural character to the structure.

The cantilever not only enhances the home’s contemporary aesthetic but also optimizes shading and spatial hierarchy. It creates covered transitional zones below, balancing openness with protection, a key response to the tropical climate.

Materiality and Contemporary Expression

Casa Mad merges clean modern lines with warm natural textures. Concrete, wood, and glass are composed with precision, generating a restrained yet expressive architectural language. Interior spaces maintain a calm material palette, allowing light and greenery to take center stage.

Carefully selected fixtures from brands such as Kohler complement the refined bathrooms and living areas, while curated furnishings enhance comfort and sophistication.

The result is a contemporary Costa Rican home that feels both grounded in its topography and elevated in design ambition.

Architecture in Dialogue with Topography

Situated within the varied terrain of San José, Casa Mad demonstrates how architecture can respond intelligently to site conditions. The composition negotiates levels and views, creating a fluid spatial progression from entry to private quarters.

The house does not simply sit on the land, it engages with it. Through terraces, balconies, and framed vistas, residents experience a continuous relationship with the city skyline and surrounding greenery.

A Model for Modern Sustainable Homes in Costa Rica

Casa Mad stands as a benchmark for sustainable luxury homes in Costa Rica. By integrating preserved trees, passive climatic strategies, courtyard typologies, and contextual sensitivity, the project offers a blueprint for environmentally conscious contemporary living.

It is a residence where architecture, landscape, and daily life converge, an elegant dialogue between built form and living nature.
