While concrete may not be a very sustainable material to work with when building houses, the newly completed MeMo House makes up for it in other green features. It is located in Buenos Aires, Argentina and was designed by the local firm Arquitectura.

The MeMo House measures a generous 2,314 sq ft (215 sq m), and is located on a narrow plot of land. It is a two story house, and the living room, dining room, and kitchen are located on the ground floor. The three bedroom and three bathrooms are located on the first floor, while the home also features a rooftop terrace and a spacious deck on the ground floor. The home has a green roof, as well as several greenery-filled areas throughout.

The walls inside the house are exposed concrete, which might not be ideal for everyone, but in the case of MeMo House it works, due to the ample amounts of greenery and natural wood. The rooms all feature large, floor-to-ceiling windows which let in plenty of natural daylight and allow for excellent cross ventilation. The borders between the indoor and outdoor spaces are also effectively blurred in this way. The windows are also fitted with large wooden shutters for when shade or privacy is needed.

While concrete may not be a very green building material, it does provide excellent thermal mass, so the home is quite energy efficient. The large windows ensure that all rooms in the house have enough light without needing to use electric lights. The home is also equipped with a rainwater collection system, and this water is used to irrigate the green areas of the home. A rooftop solar panel array harvests enough solar energy to lessen the home’s dependence on the grid considerably. The garden gate was made from leftover materials, while they made sure to compost all the biodegradable waste produced during construction.
