Karen Lloyd, the surgery’s managing partner, said in a statement there were real concerns for patients’ safety if the expansion could not be made possible.
She said about 1,000 residents would soon be living at the new £75m Friar Gate Goods Yard development. When complete, they would most likely be registering with the surgery, as it would be their closest one.
Objections were raised that the extension would mean the loss of car parking spaces, which it is feared would increase on-street parking nearby, and that the design was “not in keeping with the local area”.
A planning officer’s report responded to the concerns, but was satisfied that the plans could go ahead, the Local Democracy Reporting Service said.
The report said: “While there is a small degree of less-than-substantial harm to the listed building and the conservation area, this is outweighed by the public benefits of enhanced healthcare provision.”
Previously, the practice explored developing a new premises in Mackworth, but documents said the project made “no material progress”, leading to the expansion plans.
