A £1m refurbishment of Wigan Health Centre is being carried out by Eric Wright Special Projects, a new division of the Eric Wright Group.
The six-month project will convert rooms on the first and second floors of Boston House, Frog Lane, Springfield, into an ophthalmology centre.
Eric Wright Special Projects will strip out existing fixtures and fittings and remodel the space to accommodate the transfer of the Wrightington, Wigan & Leigh NHS Trusts Ophthalmology services from their current location on the hospital site to the health centre.
Boston House, which was built by Preston-based Eric Wright Construction in 2006, is already home to a range of health services.
These include GP services as well as a renal unit offering patients renal dialysis and a wide range of community health services including physiotherapy, long term condition services, children's services, podiatry and district nurses treatment services.
Mark Smith, construction manager of Eric Wright Special Projects, said: "We're delighted to be involved in this project, which will be of huge benefit to the local community.
"We're committed to causing as little disruption as possible and the health centre will remain open to the public throughout the works, however, the main focus of our work will be on the first and second floors of Boston House, which are currently unoccupied.
"The facilities management division of the group will be overseeing the day to day running of the health centre whilst the building work is underway."
