Full Application - Granted Conditions or Reasons: View Conditions or Reasons Informative Notes: 1 )Reasons for Granting The site comprises a two-storey semi-detached dwelling at 33 Spencer Close, Potton, constructed of facing brickwork with painted render to part of the front elevation, a tiled roof and white uPVC windows. It is situated in an established residential area characterised by dwellings of a similar age and design. The proposal seeks permission for the erection of a side first floor extension with rear rooflight and Juliette balcony. The extension would be finished in render and positioned above part of the existing single-storey side projection. It would project partially forward of the existing projection, supported by a brick column, creating a modest projecting element to the front. The pitched roof extension would be set back from the front elevation and set down below the ridge line, appearing as a subordinate addition to the main dwelling. Side extensions are a common feature within the street scene, including on the adjoining property at No. 35 Spencer Close. Whilst the extension would be sited in close proximity to No. 35, resulting in a degree of terracing effect that would be contrary to the Central Bedford shire Design Guide, an offset of approximately 0.2m from the shared boundary would be retained. Furthermore, given the staggered relationship between the dwellings, the proposal is considered to remain visually acceptable and would not appear unduly dominant or incongruous within the street scene. A materials condition can be attached. No. 31 Spencer Close forms the adjoining half of the semi-detached pair and would be screened from the proposal by the existing built form of the main dwelling. As such, the proposal would have no adverse impact on the residential amenity of the occupants of No 31. No. 35 Spencer Close lies immediately adjacent to the application site. Whilst the proposal would not comply with the 45-degree guideline in relation to windows within the neighbouring side extension, the affected ground-floor window serves a non-habitable room and the first-floor bedroom window benefits from an additional source of light on the front elevation of the original dwelling, in respect of which the proposal would comply with the 45-degree guideline. Taking these factors into account, any loss of light would not be so significant as to result in an unacceptable impact on the residential amenity of the occupants of No. 35. No other surrounding properties would be adversely affected. The proposal see an increase from a 3-bedroom dwelling to a 4-bedroom dwelling, as such three on site parking spaces would be required to meet Adopted Parking Standards. Sufficient space exists to the front of the site. On the basis of the scale and nature of the development, adequate access and parking has been retained. Neighbouring properties have been consulted on the application and no comments have been received. Potton Town Council were consulted and have no objection to the proposal. In light of the foregoing appraisal, it is considered that the proposal would be in accordance with Policies HQ1 and T3 of the Adopted Central Bedford shire Local Plan (2021), the Adopted Central Bedford shire Design Guide (August 2023), Policy HO-5 of the Potton Neighbourhood Plan, Parking Standards for New Developments SPD (August 2023), and Policy DP3 of the NPPF (2026).Reasons for Granting The site comprises a two-storey semi-detached dwelling at 33 Spencer Close, Potton, constructed of facing brickwork with painted render to part of the front elevation, a tiled roof and white uPVC windows.

The rate of Council Tax you pay depends on which valuation band your home is placed in. This is determined by the market value of your home as at 1 April 1991. Your property's Council Tax band may change if the property is extended.� The Council Tax band will only change when a relevant transaction takes place. For example, if you sell your property after extending it, the new owner may have to pay a higher band of Council Tax. If however you add an annexe to your property, the Valuation Office Agency may decide that the annexe should be banded separately for Council Tax.� If this happens, you will have to start paying Council Tax for the annexe as soon as it is completed. If the annexe is occupied by a relative of the residents of the main dwelling, it may qualify for a Council Tax discount or exemption.� Contact the Council for advice on 0300 300 8306.
