Julie Palmer and Simon Campbell, of Salisbury-based Begbies Traynor, were appointed administrators to the company this week.
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 subcontractors and trading has been difficult for some time.”
The company had 21 staff and worked on several prestigious property developments in London for a variety of clients.
