Builders' sites are areas of land that are used for the construction of buildings. They are typically large, flat areas that are cleared of vegetation and debris in order to make room for the construction of a structure. The term 'builders' sites' is often used to refer to the area where a building is being constructed, as well as the area surrounding it. The term 'LOTS' is often used to refer to these areas, as they are usually divided into smaller sections for the purpose of construction.
