Which term is associated with the proximity of a building's layout to the site boundary?

The term associated with the proximity of a building's layout to the site boundary is "Zero-Lot Line." This concept refers to a design strategy where a building is positioned very close to the property line, often up against it, with little to no space between the building and the boundary. This technique can maximize the use of space in urban settings, facilitate more efficient land use, and can enhance the walkability of neighborhoods by reducing setbacks.

Zero-lot line developments can help create a sense of community and encourage social interactions among residents, as they often lead to smaller yards and more shared outdoor spaces. It's common in urban planning, especially in densely populated areas, where land is at a premium, and developers aim to make the most out of limited space. This approach can also contribute positively to the environment by promoting higher density housing and reducing urban sprawl.

While other terms like "Edge Architecture," "Property Line Design," and "Site Alignment" touch on aspects of building layout and site planning, they do not specifically convey the same meaning or implications that "Zero-Lot Line" encompasses in relation to how close a building is placed to the boundaries of its site.
