A basement is a space located below the main floor of a building, often used for storage, utilities, or additional living areas. It is typically accessed by stairs and can be partially or fully underground. Basements can help with insulation and energy efficiency, as they maintain a more stable temperature compared to above-ground spaces. Many homes have basements that serve various purposes, such as laundry rooms, workshops, or recreational areas. Some basements are finished, meaning they are designed for comfortable use, while others remain unfinished, primarily used for storage. Proper waterproofing is essential to prevent moisture issues in basements.
