Construction work has started on a £7.5m refurbishment and extension of a 1940s property in Greenwich, London, which will house a new 145-bedroom hotel when complete.

Assael Architecture have designed the project, which involves the transformation of Maurice Drummond House - once used for residential, Metropolitan Police and student purposes.

Work will protect and upgrade the existing base building and will also preserve the Catherine Grove portico, as well as adding a rooftop extension in keeping with the property's style.

Facilities will include function rooms, a gym and a laundry area, while an existing sports hall and reception rooms will be converted for dining and function room uses.

Assael managing director John Assael said: "Construction has started on a project to transform a defunct building into a fully-functioning hotel that meets modern standards and enhances the local economy."
