A home addition is a construction project that expands the living space of a house. This can involve adding new rooms, such as bedrooms or bathrooms, or extending existing areas like kitchens or living rooms. Home additions are often undertaken to accommodate a growing family, create more functional spaces, or increase the overall value of the property. There are various types of home additions, including vertical additions, which build up by adding a second story, and horizontal additions, which extend outward. Homeowners typically work with contractors and architects to design and execute these projects, ensuring they meet local building codes and regulations.
