- Full Application - Granted Conditions or Reasons: View Conditions or Reasons Informative Notes: 1 )Reasons for Granting The site comprises a single-storey terraced bungalow at 46 Oak Crescent Biggleswade constructed of red brick with a tiled hipped roof. The bungalow is attached to the end of a terrace of two-storey dwellings of similar materials within an established residential area. The proposal seeks permission for the erection of a single-storey rear extension finished with a flat roof set behind a parapet wall. The extension would adjoin a similarly designed extension approved under ref: CB/18/1863/Full. As it would be located to the rear it would not be visible in the streetscene. Having regard to its scale, form, height and design, the proposal would not result in unacceptable harm to the character or appearance of the dwelling itself or the surrounding area. A materials condition can be attached. The neighbouring property, No 44 Oak Crescent, forms part of the attached terrace and lies to the north of the application site. Its covered side access adjoins No 46, with a brick boundary wall and outbuilding located along the shared boundary. The nearest ground-floor rear window at No 44 serves a kitchin, which is a non-habitable room. The proposed extension would be set approx 0.4m from the shared boundary and, given the relationships involved, would not result in any material loss of light, privacy or overbearing impact to the occupants of No 44. The submitted plans also show the insertion of a ground-floor bathroom window in the eastern elevation. This alteration could be undertaken under permitted development rights and would be well offset from the adjacent dwelling, No. 48 Oak Crescent. As such, it is considered acceptable in this residential context. Accordingly, the proposal would not result in any unacceptable impact on the living conditions of neighbouring occupiers, and no material harm would arise to the occupants of any surrounding property. The submitted plans show that the proposed extension would provide an additional ground-floor bedroom. Whilst this room would not meet the Nationally Described Space Standards (NDSS), the position and layout of the extension are such that the space could readily be used as ancillary ground-floor living accommodation. Furthermore, the two existing off-street parking spaces would be sufficient to meet the adopted parking standards. Neighbouring properties have been consulted on the application and no comments have been received. A small Elder tree to the rear of the site would need to be removed, the Tree Officer has no objection to the proposal. Biggleswade Town Council were consulted and have not commented on 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 Bedfordshire Local Plan (2021), Policy BPD3 of the Adopted Biggleswade Neighbourhood Plan, the Adopted Central Bedfordshire Design Guide (August 2023), the Parking Standards for New Development SPD (August 2023) and Policy DP3 of the NPPF (2026).Reasons for Granting The site comprises a single-storey terraced bungalow at 46 Oak Crescent Biggleswade constructed of red brick with a tiled hipped roof.

Any other consent or approval which is necessary must be obtained from the appropriate authority. 5 )Will a new extension affect your Council Tax Charge? 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.
