Casa Efi is defined by what you do not notice. No drafts. No temperature shifts. No mechanical noise. Just a constant, even sense of comfort that remains the same from room to room and across the seasons.

Certified under the Passivhaus standard, the house is designed to maintain a stable indoor climate with minimal energy use. High-performance insulation, airtight construction and a continuous ventilation system work together silently in the background. The result is not visible, but immediate.

With a south-west orientation and large windows, the house engages naturally with light throughout the year. Winter sun enters deeply. In summer, it is filtered and controlled. The architecture responds to the environment rather than resisting it.

The house unfolds across multiple levels, balancing openness and privacy. On the ground floor, two bedrooms open directly onto the garden and outdoor pool. The technical areas remain discreet, supporting the performance of the house without intrusion.

The main living level begins with an interior garden, a transitional space that sets the tone. Beyond, the living room is centred around a three-sided fireplace, visible from multiple angles. The dining area connects to a generous, open kitchen, designed for both daily use and gathering. From here, the house extends outward to covered porches and a landscaped garden with organic lines.

Also on this level, an indoor heated pool forms part of the architecture itself. A quiet, unexpected space where water, light and reflection become part of everyday life.

The upper floor is dedicated to the main suite, with large openings overlooking the garden and pool. Two dressing rooms and a bathroom designed for shared use create a self-contained private area.

At the top of the house, a more secluded level accommodates a study with a double-sided fireplace, its own bathroom and access to a large solarium. A quieter space, oriented toward the garden.

All bathrooms are exterior and designed with the same coherence as the rest of the house. Nothing feels secondary.

Set on a plot of 2,364 m², the property includes both outdoor and indoor swimming pools, parking and landscaped grounds.

Casa Efi is not defined by visible features, but by performance and precision. A house where efficiency becomes architecture, and comfort remains constant.
