- Full Application - Granted Conditions or Reasons: View Conditions or Reasons Informative Notes: 1 )Reasons for Granting: The application site is a semi-detached, two-storey dwelling located on the east side of Church Street, Langford. No. 99 is constructed of red and buff brickwork featuring black timber framing, white render, and a tiled gable roof with a gable front projection. The property currently benefits from a single-storey rear projection and open canopy porch to the principal elevation. The proposal consists of the erection of a single-storey side/rear extension with a rooflight, a front porch extension, a loft conversion with rear box dormer and the installation of an obscure glazed, side facing window to the existing gable. The proposed rear extension would have a depth of 6.7 metres, a width of 7 metres, and an overall flat roof height of 3.2 metres. The proposed front porch would have a depth of 1.2 metres, a width of 1.9 metres, and would retain the eaves and mono-pitched roof of the existing porch canopy. To the rear roof slope, the proposed dormer would have a depth of 3.5 metres, a width of 6 metres, and a maximum flat roof height to 2.6 metres. Church Street is characterised by dwellings of varied age, scale and design, with several extensions to other properties evident within the streetscene. The proposed side/rear extension would be largely retained to the rear of the property, extending beyond the south (side) elevation of the dwelling by some 1.5 metres. This would remain set back from the streetscene by a minimum of 15.5 metres, and therefore would not form a prominent feature within the public realm. This addition would be sited on existing hardstanding and partially within the footprint of the existing rear projection, and therefore would form a proportionate addition to the host dwelling. To the front of the property, the proposed porch extension would remain entirely within the footprint of the existing porch canopy and would not exceed the established building line of this elevation. A variety of frontages across the area are noted, and therefore this extension is considered a minor alteration which would not give rise to any adverse impact to the character and appearance of the area. To the rear roof slope, the proposed rear dormer would also form a proportionate addition to the host dwelling, confined to the rear roof slope and therefore not readily visible within the streetscene. The dormer would also be of a scale comparable to that which could be reasonably achieved under permitted development rights. This extension would be finished in materials to match that of the existing roof and as such the proposal is not considered to give rise to any detrimental impact on the character and appearance of the area. The proposed new window would represent a minor addition to the host dwelling, which would have no material impact on its character and appearance. Regarding the siting of the proposal, the most potentially impact neighbouring dwellings are deemed to be adjoining neighbours No. 97 and No. 101 Church Street. To the north, the proposed rear extension would be sited adjacent to the shared boundary with No. 97 Church Street, however, would not surpass the depth or height of the existing rear projection at the application site, which currently sits on along this boundary. Given this relationship, this neighbouring dwelling would remain entirely screened from the proposal and the works would not give rise to any impacts on neighbouring amenity. To the south, the proposal would be sited some 2.8 metres from No. 101 Church Street, given this retained separation distance, and the single-storey nature of the extension, it would not be considered to give rise to any overbearing impact or loss of light to this neighbouring dwelling. The proposal includes the installation of an obscurely glazed, second-storey window to the south elevation facing No. 101, this neighbouring dwelling has no upper floor windows on the north elevation, and as such there would be no opportunities for overlooking or loss of privacy between properties. The proposed rear dormer would be retained at roof level and would not overlook any properties to the rear of the dwelling, and as such would not be considered to give rise to any adverse impacts on the amenity of neighbouring dwellings. The proposal would increase the number of bedrooms in the dwelling from three to four. As shown on plan number A010 there are sufficient parking arrangements for three spaces at the property and adequate parking has been retained in line with the Parking Standards SPD. Langford Parish Council were consulted on this application and did not provide any comments. The Archaeological Officer was consulted on this application and raised no objections. The application was subject to public consultation and no representations were received. The proposal is therefore considered to be in accordance with the Langford Neighbourhood Plan, Policies HQ1, T2 and T3 of the Central Bedfordshire Local Plan, Section 11 of Central Bedfordshire Design Guide, Parking Standards for New Developments SPD and Chapter 14 of the National Planning Policy Framework (NPPF).Reasons for Granting: The application site is a semi-detached, two-storey dwelling located on the east side of Church Street, Langford.

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.
