This remarkable Cylinder House designed for Lyon, France, takes modular architecture to the next level. Cyril Lancelin, French architect and founder of creative studio Town and Concrete, imagines the house as a large cluster of modular glass tubes. The building weaves in and out of existing trees, and it can be expanded without disrupting the wooded surroundings.

The architects used a system of cylinder juxtaposition to allow future extensions of the house, but also meander around trees to preserve the existing state of the landscape. Cylinders were chosen for their malleability – they can be open, semi-open or closed, depending on the function and place within a larger configuration.

The interior spaces, delineated by differences in cylinder heights, are flexible and respond to the lifestyle of their occupants. It is an open plan, with the cylinder pieces acting as posts.

There are no corridors or walls inside the structure, which makes it spatially economic and airy. Its undulating glass facade blurs the line between the inside and the outside, and offers beautiful views of the forest.
