What is the common form of housing that is often less expensive and made in sections?

Modular homes are a common form of housing known for being constructed in sections or modules. These homes are built in a factory setting and then transported to the site for assembly, which often results in lower construction costs compared to traditional on-site building methods. The modular construction process allows for greater efficiency and time savings, contributing to their affordability.

While townhomes, duplexes, and cooperative housing also serve as forms of housing, they typically do not involve the same sectional modular construction. Townhomes are usually connected homes sharing one or two walls, duplexes are two-family homes that are side by side or stacked, and cooperative housing involves a shared ownership structure. Each of these types has different characteristics and often different cost structures, but modular homes stand out specifically for their sectional construction and generally lower price point.
