Hampshire County Council, not the borough, issues the crossing, and it carries a warning aimed straight at the customer: "Please be aware that some contractors may not be applying for the necessary road opening licence when installing vehicle crossings. Please ensure that your chosen contractor has obtained all relevant permissions and you have seen evidence of this before commencing work."
The county sets the order of the job as the applicant appointing the contractor, the contractor applying for a Section 171 licence to excavate the highway, the licence being assessed, and then "Applicant must view Section 171 licence before work starts". It states that "Roads listed A, B or C are classified roads. If access is taken from a classified road you will need planning permission", that approval is valid for 12 months, and that "Where applicable, Planning Permission does not override the technical requirements of the crossing approval".
Eastleigh Borough Council lists eight conservation areas, Bishopstoke, Botley, Old Bursledon, Bursledon Windmill, Gaters Mill West End, Hamble-le-Rice, Netley Abbey and Orchards Way West End, and states that an Article 4 Direction "limits the works that can be carried out without needing planning permission from the Council". Its directions include the Bishopstoke, Botley, Old Bursledon, Orchards Way, Netley and Romill Close conservation areas.
The Planning Portal carries the national front garden rule. An eligible house with the relevant permitted development rights may be paved with permeable surfacing or drained to a lawn or border without an application, and impermeable paving over five square metres needs permission where it does not drain to a permeable area.
We would explain how you check the conservation boundary, any Article 4 direction, the Section 171 licence and the proposed work before confirming whether permission is needed.
