The term vault in architecture refers to a self-supporting arched structure that forms a ceiling or roof, which can effectively create a wide, column-free space. While traditional masonry vaults transfer loads to walls and buttresses, contemporary versions are more broadly defined as any ceiling that follows the roofline, creating a high, curved interior. These modern ceilings are typically framed using materials like concrete, timber, or steel, which provide the structural flexibility to create the dramatic effect of a vault without its historical constraints. The round arch vault, in particular, seems to have been a recently favored form for its simple, elegant geometry and its ability to adapt to a variety of modern residential styles.
The private space is usually associated with hiding what goes on inside, allowing people to have certain moments of intimacy. Habitually, bathrooms have been designed for this purpose, reducing openings to a minimum or — sometimes — eliminating them completely.
However, being such an important space within a building, bathrooms have become an object of new exploration for architects. By blurring the limits of privacy — without losing it completely — these spaces are open to the outdoors, allowing the breeze to enter. How does this new experience feel? Check out 30 open bathrooms that play with the feeling of exhibitionism, without fully revealing what is happening inside.
The challenge of designing a house with a tight budget and space constraints, together with the essential duty of responding correctly to the requirements of the user, is sometimes one of the most challenging and motivating tasks an architect can face. How can you take advantage of space most effectively? How can you avoid wasted material? How do you anticipate the possible future expansion of the house? And how do you develop a simple design that also delivers value to its inhabitants?
To help you in this process, we scoured our projects archives to select 30 houses that provide interesting architectural solutions despite measuring less than 100 square meters.
Circulation spaces are often challenging for designers as they are intended—as the name implies—for moving from one room to another. While many take advantage of these areas by using them as storage spaces, Mies van der Rohe at the Farnsworth house reduced circulation to a minimum, creating an open floor plan completely free of hallways. When faced with vertical circulation, the issue is similar. Stairs fulfill the purpose of overcoming the height between one floor and another, but rarely constitute indoor living spaces. Bleachers, in turn, play this role in several projects. Until recently, they were only found in sports spaces or amphitheaters; now the use of bleachers has become widespread and is seen in office spaces, public buildings, schools and even homes.
