General Policy 2
Requires development to respect site/surroundings in siting/layout/scale/design, not adversely affect landscape/townscape character, local residents' amenity or locality character. Officer assessed extension as compliant due to concealed rear location, matching materials, subordinate appearance and no neighbour amenity harm; flue acceptable as no visual/emissions impact.
Environmental Policy 22
Prohibits development unacceptably harming environment/amenity via airborne pollutants (ii). Flue assessed compliant as positioned to avoid neighbour impacts (unlike precedent), with Building Control confirmation on installation standards and no evidence of harm.
Residential Design Guide 2021
Sections 3.1 (general extensions), 3.2.2 (prefer pitched roofs lower than main ridge, replicate features), 4.2.3 (limit single-storey depth to 3m for semi-detached), 5.1.3 (flue placement/appearance). Flat roof and 5.9m depth at variance but accepted due to site-specific concealment, materials match, no overlooking/overbearing, and flue mitigation via position.
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.
No Highway Interest
no objections from what he has told me
Marown Parish Commissioners suggested improving the flat roof appearance with a lantern replacement but did not object; Highways Division had no interest; a neighbour had no objections.
Key concern: presumption against flat-roofed extensions
Marown Parish Commissioners
Conditional No ObjectionThe Commissioners are aware of a presumption against flat-roofed extensions which they support.; provision of a pitched roof would be difficult or impossible owing to the design of the house.; The extension at the rear of the property would not be visible from the Highway.; The Commissioners resolved that the appearance could be improved with the replacement of the Sun Tunnel by a Lantern which would serve to break up the flat roof for the benefit of views from neighbouring properties.
Conditions requested: replacement of the Sun Tunnel by a Lantern which would serve to break up the flat roof
