What does a Builder do?
Builder, person who builds, principally houses but also similar structures, such as schools and small office blocks, where house-building skills are required. More elaborate structures, such as hospitals and roads, are usually built by engineering contractors.
There are three main types of builders: (1) the jobbing builder who undertakes small jobs in all trades, typically concentrating on maintenance work; (2) the contractor who employs craftsmen and labourers, and contracts to erect buildings for a client, possibly with the help of sub-contractors for specialised work; (3) the speculative builder who builds houses on his own land and at his own risk, hoping to sell them. Speculative building has been practised in England since the 16th century. Builders range from small, local firms to large, national concerns.
