A report says a "major design flaw" led to residents in Stirling complaining about a new £85 million women's prison.
HMP Stirling was opened a year ago, replacing Cornton Vale.
Residents have raised complaints about noise and anti-social behaviour.
A report by HM Inspector of Prisons Scotland said separation units are "located within sight and sound" of nearby residents.
The Scottish Prison Service say they're "working hard" to address issues.
A Scottish Prison Service spokesperson said: "It is just over a year since we opened HMP & YOI Stirling. We recognise there are areas where improvement is needed and are working hard to address these for our staff, those in our care, and our neighbours.
“Our transformative and groundbreaking Strategy for Women in Custody, supported by significant investment from the Scottish government, has delivered a step change in how we support the rehabilitation of those in our care, reducing the risk of reoffending, and helping to build safer communities.”
