Parasitic wooden cubes level up 1970s Parisian building with more space, more energy efficiency

Companion cubes!

“Parasite” wooden cubes may help extend the livelihood of old buildings by increasing available space and improving energy efficiency. The cubes were designed by architect Stéphane Malka as part of the Plug-in City 75 project and will be attached to the facade of a 1970s-era Parisian building slashing its annual energy consumption by roughly 75 percent.

Faced with gloomy, cramped apartments and poor energy efficiency of a by-gone era of building, the co-owners of a Parisian building in the city’s 16th arrondissement asked Malka to spruce up their property. It’s just one of many buildings facing these issues in Paris, but since the city’s building laws are quite restrictive and do not allow for the building to be raised to make way for better, more efficient space, he couldn’t just tear it down and replace it.

So he decided to level it up. And what better way to do that than with a class of modular add-ons that also look really cool?

Companion Cubes

Malka designed a type of “parasitic architecture” to solve both problems at the same time. The design calls for a series of bio-sourced wooden cubes to be mounted onto the structure — extending the useful space horizontally through openings in the exterior.

This extension would also reduce the total energy consumption of the building by a factor of four — its current consumption of 190KWh/sq. meter would drop significantly, to 45KWh/sq. meter.


These cubes will be made from a lightweight-but-strong mix of wood particles and chips which can be easily transported and assembled on site by workers.

Once affixed to the building, they will not only increase living space and allow more light to enter the building, but also allow for an inner garden courtyard on the first floor. The new facade will also be draped with hanging plants, which will make it even prettier.
