Appeal 3271126

The appeal is allowed and planning permission is granted for a part single part two storey side and rear extension at [site address] , Southgate, London [postcode] in accordance with the application, 20/5334/HSE, dated 9 November 2020, subject to the Schedule of conditions at the end of this decision.

The main issue is the effect of the proposed development upon the character and appearance of the host property and the area.

The appeal property is a two-storey semi-detached dwelling located within a residential area. The front has a mock Tudor appearance whereas, the property, to the rear is simpler in appearance and benefits from a two-storey projection and an outbuilding. The appearance of dwellings, along the street, together with the generous spacing between them creates a pleasant suburban environment.

The proposed first floor extension would extend beyond the side wall of the host property and include a gable roof design. I find that the proposed development would be proportionate to the size of the host property and would not be overly dominant. The extension would reflect the simpler form of the rear of the property and represents a subservient addition through its size, set back and lower ridge line.

Whilst the proposed window would be wider than the window in the host property, I find that this would not unacceptably harm its appearance given the size of the host property and the proportions and scale of the proposal.

The proposed development would not unduly harm the character and appearance of the host property or the area. It accords with Policies CS1 and CS5 of the [name] (2012) and Policy DM01 of the Development Management Policies Development Plan Document (2012) which, amongst other things, seek the highest standards of urban design and developments to respect local context and character.

It would accord with guidance set out in the Council’s Residential Design Guidance Supplementary Planning Document (2016) which, amongst other things, sets out that extensions should be consistent with the form, scale and architectural style of the original building.

I have considered the imposition of conditions in accordance with the National Planning Policy Framework and Planning Practice Guidance. I have imposed a condition specifying the relevant drawings as this provides certainty. A condition requiring matching materials is necessary in the interests of safeguarding the character and appearance of the area.

Conditions for obscure glazing and restricting additional windows in the side elevation facing No.112 have been imposed in the interests of safeguarding the living conditions of neighbouring occupants.

For the reasons set out above the appeal succeeds.

The development hereby permitted shall begin no later than 3 years from the date of this decision.

The development hereby permitted shall be carried out in accordance with the following approved plans: [name] 3076/1; [name] 3076/2; [name] 3076/3; [name] 3076/4; [name] 3076/5; [name] 3076/6; Site Plan and Block Plan.

The materials to be used in the construction of the external surfaces of the development hereby permitted shall match those used in the existing building.

The upper floor window in the side elevation facing [address] shall be non-opening and fitted with obscure glazing prior to occupation and shall then be retained thereafter for the lifetime of the development.

Notwithstanding the provisions of the Town and Country Planning (General Permitted Development) (England) Order 2015 (or any order revoking and re-enacting that Order with or without modification), no additional windows or doors shall be inserted in the side elevation of the development hereby permitted facing [address].
