Which sector of construction focuses on the building of single-family homes?

The focus on single-family homes falls under residential construction, which is specifically dedicated to the construction of houses and living spaces designed for individuals and families. This sector involves various aspects of home building, from planning and design through to the actual construction processes that create livable structures.

Residential construction is distinct from other sectors, such as commercial construction, which deals with building structures meant for business or public use, and industrial construction, which focuses on factories and plants. Additionally, infrastructure construction includes projects like roads, bridges, and utilities, which serve a public purpose rather than private living spaces. Therefore, when discussing the sector specifically responsible for the building of single-family homes, residential construction is the clear and correct choice.
