Casa MM proposes a sustainable and highly efficient architecture, adapted to the climate, the topography, and the surrounding views. Organized into independent volumes and strategically oriented, it optimizes energy performance, natural ventilation, and comfort, following Passivhaus principles with low construction costs and minimal maintenance.

Casa MM proposes a sustainable and highly efficient architecture, adapted to the climate, the topography, and the surrounding views. Organized into independent volumes and strategically oriented, it optimizes energy performance, natural ventilation, and comfort, following Passivhaus principles with low construction costs and minimal maintenance.

This house looks for the maximum energy efficiency adapting itself to the program, the solar orientation, the views and the slope of the terrain.
The project optimizes the program grouping it in four boxes –kitchen, living-dinning, main bedroom and guest bedrooms- which can be used together or independently. Each box is placed carefully on the ground and rotates on its axis with precision to find the best views and orientation for their use.
Each box has large openings towards the best orientations and sights, and smaller openings on the opposite façade allowing cross ventilation and taking advantage of the East-West breezes of the place. The South openings are recessed to let the sun enter in winter and block it in summer, while the East and West openings have exterior shutters. The house has been designed according to PASSIVHAUS standards to achieve the maximum energy efficiency.

The house has been designed according to Passivhaus standards to achieve maximum energy efficiency.
A rigorous infographic study was carried out to ensure optimal heat gain, maximizing it in winter and minimizing it in summer.

The façade has an exterior insulation system that increases the insulation thickness up to 15cm and strictly guarding all joints to completely avoid any thermal bridge. The infiltrations through the façade have been reduced to the minimum, and the hermeticism of the enclosure has been maximized to overcome pressurization tests in every space.

The energy used to heat domestic hot water is obtained almost entirely from the solar thermal installation. The pitched roofs are equipped with a rainwater collection system: three of the roofs collect water for irrigation, while the fourth roof is “clean” and collects water for domestic use.
To this end, two independent cisterns are provided—one with a capacity of 40 m³ and the other of 8 m³—strategically located in the voids created between the house and the sloping terrain.
The mild climate of Mallorca is taken advantage of to avoid the need for a mechanical ventilation system with heat recovery, instead relying on cross ventilation. Thanks to this design, no cooling system is required, and the heating demand is only 11 kWh/(m²·year), which is met through a compact perimeter underfloor heating circuit.

Each of the boxes features smaller openings on its opposite façade, allowing for cross ventilation and taking advantage of the site’s east–west breezes. The south-facing openings are recessed to allow winter sunlight to enter while blocking the summer sun, whereas the east- and west-facing openings are protected by adjustable external louvered shutters.

The project is carried out with a low construction cost and a very low energy maintenance cost.
