"The home is currently in the final stages of being fitted out and external works are in progress.
"I was shown a variety of facilities that should create an excellent home for many new residents.
"The benefits of the location being near to so many local facilities such as the library, shops and post office will be very useful.
"I was encouraged to hear that the management has plans to help the home and residents to become an integral part of the local community."
And he added: "I am very aware that this proposal was not universally welcomed during the planning stages, and I sought reassurances that they were implementing the required flood alleviation systems, and that they will be providing their own car park for staff and visitors."
Greg was accompanied by Buckingham ward councillor Warren Whyte, who took the opportunity to push for a revised proposal for the Cornwall's Meadow entrance area, to make sure it is pedestrian and cycle friendly.
