La Maison Vague: Lovely on the Outside, But Inside… Meh
La Maison-vague is a green-roofed design from French designer Patrick Nadeau, currently being built in Reims for Effort Remois. Like a similar design in the UK, it is a design for an affordable housing project. This green roof mound shape is becoming a familiar one. An entire Swiss eco hotel is comprised of the same mounds.
In practice, it would be a challenge.
It is a useful shape. Carbon emissions and energy costs are reduced, because the design is energy-efficient, resulting from the insulating properties of the earth layer covering that supports the green roof. Building costs are low.
Both earth and plants insulate against both heat and cold, helping maintain year-round comfortable temperature ranges. An automatic misting system that senses dryness keeps them refreshed in the event that the weather fails to supply them.
It is not too steep for ground cover to grow. The ground cover plants are selected for their ease of growing at various degrees of steep inclines and constitute a mix of grasses, leafy succulents, thymes, lavenders and other small aromatic and perennial plants.
