The phrase describes a search query used to locate local contractors or companies specializing in the construction of additional living spaces attached to existing residential structures. For example, a homeowner seeking to expand their kitchen might type those words into a search engine to find local construction services.
Locating nearby professionals offers several advantages, including easier communication, reduced travel costs for project assessments and construction, and the ability to leverage local knowledge of building codes and permit requirements. Historically, homeowners have relied on word-of-mouth and printed directories to find such services; the internet has streamlined this process considerably.
