The officer assessed the proposal against General Policy 2 (GP2) of the Isle of Man Strategic Plan 2016, finding it compliant in terms of character and appearance (GP2 b,c) as it would not look out of…
General Policy 2
GP2 sets general standards for acceptable development, including character/appearance (b,c) and neighbouring amenity (g). The officer found the extension's form, mass, and design suitable despite not being subordinate in height, due to presumption for residential extensions and local precedents; no adverse amenity impact from minimal overlooking and non-overbearing scale.
Transport Policy 7
TP7 addresses parking standards and highway safety. Acceptable despite narrow garage, as one space retained on-site, nearby communal parking available, and conditioned for vehicle storage only per Highway Services advice.
Residential Design Guide 2021
Guidance on good neighbourliness and overlooking. Proposal deemed compliant with minimal overlooking from wardrobe window and no side windows impacting No.45.
Time limit
The development hereby approved shall be begun before the expiration of four years from the date of this decision notice. Reason: To comply with Article 26 of the Town and Country Planning (Development Procedure) Order 2019 and to avoid the accumulation of unimplemented planning approvals.
Garage parking use
The garage hereby approved shall at all times be made available for the parking of private motor vehicles and shall be retained available for such use. Reason: To provide adequate off-street parking.
Pre-commencement drainage and driveway details
Prior to the commencement of the development hereby approved, the drainage details at site entrance, and details for drainage management and surfacing for the driveway shall be submitted to and approved in writing by the Department. Reason: In the interests of highway safety.
No significant negative impact upon highway safety, network functionality and/or parking providing the garage is conditioned for the storage of vehicles only.
Allowing surface water runoff onto a public highway would contravene Section 58 of the Highways Act 1986 and guidance contained in section 11.3.11 of the Manual for Manx Roads (implying need for drainage condition).
The Board resolved to support the proposal.
