The existing access, by which vehicles associated with this proposal would leave and re-join the County Highway is unsatisfactory since the required driver to pedestrian visibility of 2 metres x 2 metres cannot be achieved at the junction with the County Highway and therefore, in the opinion of the Planning Authority, the intensification of use which would result from the proposed development is unacceptable in terms of highway safety.
The proposal by reason of the size of the extension proposed and the level of accommodation created would be contrary to the provisions of Development Policy 19 of the NYM Local Development Framework which seeks to ensure that detached annex accommodation is provided within existing buildings and the accommodation provided is ancillary to the host dwelling in terms of its scale and specification.
