Checked on 6 October 2026. The pin for this application is the centre of its postcode rather than the building, so distances to nearby designations are measured from the postcode and can be out by the width of the postcode area.

A boundary can run through a site and the council holds the definitive record: confirm with the council before relying on this.

- Full Application - Granted Conditions or Reasons: View Conditions or Reasons Informative Notes: 1 )Reasons for Granting The site comprises a two-storey detached dwelling at 27 Birch Close, Broom, constructed of brickwork with hanging tile, a tiled roof and white uPVC windows. It has a flat roofed double garage to the side and a conservatory to the rear. The property is location within an established residential cul-de-sac of a similar age and character. ��� The proposal comprises the removal of the conservatory and erection of a single storey rear flat roofed extension with roof lantern. Due to its scale and siting it would appear subservient to the main dwelling and would not be visible from the streetscene. A single storey infill side extension is also proposed between the dwelling and garage to form a new entrance porch, including a partial garage conversion. A pitched roof would extend over the infill and existing garage, incorporating a front canopy. Minor alterations to ground floor fenestration on the side and rear are also proposed. Overall, the side extension would read as a cohesive, set-back, and subservient addition. A materials condition can be attached. The rear garden of No 23 Broom Close lies to the north of the site. Given the single-storey scale of the proposed development and its separation from the boundary, no adverse impact on the residential amenity of this property would arise. No. 25 Birch Close lies to the west, offset approximately 1.8m from the shared boundary. While the proposed 4.6m deep rear extension would be slightly larger than the conservatory it replaces and would extend to the boundary, its single-storey form and the retained separation to No. 25 would avoid any unacceptable loss of light or overbearing impact. A condition can be attached to ensure it remains blank sided to protect neighbouring privacy. The proposed pitched roof over the garage would be adjacent to the flat-roofed garage at No. 29 Birch Close, which sits forward of the dwelling and contains a ground-floor kitchen window nearest the boundary. Given the scale of the roof alteration and the relationship between the properties, no undue loss of light, privacy or overbearing impact would result. Overall, by virtue of its scale, siting and design, the proposal would not have a detrimental impact on neighbouring residential amenity. On the basis of the scale and nature of the development, adequate access and parking has been retained. The proposed development lies within the historic core of Broom (HER 17138), a heritage asset of archaeological interest as defined by the NPPF. However, given the limited scale and nature of the works, partly within the existing conservatory footprint, significant impacts on archaeological remains are unlikely. Therefore, no objection is raised on archaeological grounds. Neighbouring properties have been consulted on the application and no comments have been received. Southill Parish 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 Bedford shire Local Plan (2021), the Adopted Central Bedford shire Design Guide (August 2023), the Parking Standards for New Development SPD (August 2023) and Section 12 of the NPPF (2024).Reasons for Granting The site comprises a two-storey detached dwelling at 27 Birch Close, Broom, constructed of brickwork with hanging tile, a tiled roof and white uPVC windows.
