In relation to a dwelling, a basement is a part of a dwelling that is partly or entirely below ground level and is designed for habitation. It is distinct from a cellar, which is typically used for storage, housing heating plant, or other non-habitable purposes. Basements can include living spaces, bedrooms, or utility rooms, provided they meet the necessary building regulations for habitability.
A basement is a functional and habitable space within a dwelling that is partially or fully situated below ground level. Unlike cellars, which are primarily used for storage or housing mechanical systems, basements are designed to be lived in and must comply with specific building regulations to ensure safety, comfort, and accessibility. In the UK, basements are increasingly popular in urban areas where space is limited, and they are often used for additional living areas, home offices, or recreational spaces.
Synonyms: Lower ground floor, subterranean level
