Plans to build 153 homes on the site of the former planning offices at South Hill have been rejected.
The decision is despite the application being recommended for approval by officers.
The Jersey Development Company also proposed a cafe and courtyard, a refurbished children's park, and 274 bike and 70 car parking spaces.
The Planning Committee rejected the scheme - mainly because of concerns about the scale of the development.
Consent was being sought for 70 one-bedroom and 56 two-bedroom flats within three blocks - the highest of which would have been nine storeys.
The Jersey Development Company said it wanted the development to achieve the highest environmental standards.
“The aim is to regenerate and redevelop this site through high quality urban design involving the introduction of new residential, or visitor accommodation and associated uses, into the area, helping to develop a sense of place and positively contributing to the development of a vibrant St. Helier waterfront.” - JDC.
At least 15% of the homes in the development would have been 'affordable' and set aside for first-time buyers
The Planning Committee voted 4-1 against the plans.
