The scheme involves a number of buildings being demolished and replaced with 172 one-bedroom, 85 two-bedroom and five three-bedroom social-rented apartments.
The development is being built by developer Dandara for Andium Homes.
As well as a loss of privacy, the Belmont Court Association also argues that the development will lead to a loss of daylight and create light and noise pollution.

It adds that there has been a lack of clarity around the commercial use of the brewery and café, including opening times, and details about waste removal, odour levels, and internal lighting.
If the appeal is rejected and the development goes ahead, ‘Sans Souci’, a property on St. Saviour’s Road, will be refurbished and extended to become the new headquarters of Autism Jersey.
Also, Belmont House – on the corner of Simon Place and Ann Street – will be refurbished as a café on the ground floor with two apartments above.
The old brewhouse next door will be refurbished and extended as a micro-brewery and offices.
Another property, 12 Simon Place, will also be refurbished and enlarged to create two one-bedroom and five three-bedroom apartments. It is planned to retain five of the seven listed buildings on the site.
The appeal will be heard by an independent planning inspector on a day yet to be determined.
