The company had been operating since 1999 but has now decided to cease trading.
Julie Palmer and Simon Campbell of Salisbury-based restructuring specialists Begbies Traynor were appointed administrators to the company on December 10.
Mrs Palmer said: “Some final completion works were carried out on a small number of contracts in the run-up to the administration order, but the employees have now been made redundant. The construction sector is particularly tough at the moment for sub-contractors and trading has been difficult for some time.”
The company had 21 employees and worked on a number of prestigious property developments in London for a variety of clients, the administrators said.
