Larne Area Plan 2010
Carncastle is situated 2 kms to the west of Ballygalley and consists of a cluster of development around the junction of the Carncastle and Ballygalley Roads. The development of the settlement has focused on three churches, halls and a public house. It has been and will continue to be constrained by the surrounding topography.
The Department proposes to limit the further expansion of Carncastle in order to protect its character.
The location and scale of the settlement give it considerable character. There are a number of existing small infill sites suitable for development which are in keeping with the scale of the settlement
