You know those glass tubes at the bank drive-through that shoot your deposits and withdrawals back and forth between you and the tellers? This house is like living in a cluster of them. Sadly, they’re not full of money, but it’s still pretty cool. ‘Cylinder House’ by lead architect Cyril Lancelin of the firm Town and Concrete is a modular glass residence in Lyon, France that can easily be expanded and rearranged without disturbing the trees around it by adding or subtracting one glass tube at a time.

Set on plinths, the tubes are narrow enough to allow for optimal malleability, conforming to the site. Some are taller than others, and some seem to hover above the landscape. The tubes can be fully open to each other, partially open or closed off altogether for smaller spaces. There are no walls or hallways inside other than the curving glass.

“The furniture marks space, but its movement can reinvent the house,” say the architects. “The plan is not fixed, to follow the evolution of the lives of these occupants. From the outside, the facades undulate… this system of cylinder juxtaposition allows to enlarge the house but also to have a blurred outer delimitation of the house with its context.”

The effect is definitely unusual when viewing the house from outside. As modular designs become more popular, their inventiveness only increases. It’ll be interesting to see how architecture as a whole is affected by the trend in the coming years.
