It doesn’t get anymore sustainable than this. Cork, the same stuff that makes bottle stops, is now being applied on a mass scale in building design.

Now, this isn’t the first time that cork has been used in the construction of buildings. Traditionally used in the role of insulation, cork is now assuming a far more prominent role in homebuilding.

At Berlin’s Cork Screw House, for example, the Rundzwei studio has created the aptly named single-family residence known as the Cork Screw House. Consisting entirely of Cork, the home strikes an interesting contrast to the traditional homes that line its neighbourhood.

Designed to be both contemporary and monolithic in style, the home compliments its visual appeal with a whole host of sensory effects, offering a pleasant feel and smell and even shifting colour when it rains. It also supplies acoustic and weather insulation and a natural vapor barrier.

In addition to its visual appeal, cork is a highly sustainable material that—once it reaches full maturity at 25 years old—can be harvested every nine years for the lifespan of the tree—which could be, on average, 250 years. This material can regenerate itself naturally, and is shapeable and lightweight.

With everything from furniture to art being created from cork, it is high time that building designers caught up with the trend—working and corking up the formula for a splendid and sustainable building design!
