- Full Application - Granted Conditions or Reasons: View Conditions or Reasons Informative Notes: 1 )Reasons for granting The application site relates a detached two-storey dwelling located on Bedford Avenue, Silsoe. No. 10 is constructed of brickwork with a tiled pitched roof and is surrounded by properties varying in design and scale. The proposal consists of the erection of a single-storey rear extension with a pitched roof following the demolition of an existing conservatory. Also included within the proposal are fenestration changes to a side elevation. The rear extension would have a proposed width of approximately 4.9 metres, a depth of 4.6 metres, an eaves height of 2.7 metres and a maximum height of 4.2 metres. The rear extension would have a similar footprint to that of the existing conservatory, increasing the properties footprint by approximately 7m2, and therefore would be considered proportionate to the host dwelling. The rear extension would not be visible within the street scene and therefore would not a detrimental impact on the character and appearance of the area. Overall, the proposed development is not considered to have a detrimental impact on the character and appearance of the area or the host dwelling, and is in accordance with Policies HQ1of the Central Bedfordshire Local Plan. In terms of neighbouring amenity, the rear extension would be separated approximately 1.4 metres from the shared boundary with the neighbouring property to the rear,14 Bedford Avenue, and 2.5 metres to the property itself. This separation distance, combined with the extension only being moderately larger than the existing conservatory, result in the extension not being considered to have a detrimental impact on the residential amenities of this neighbour. The other neighbouring property close to the proposed extension, 12 Bedford Avenue, would be further separated from the rear extension with a separation distance of 1.8 metres to the shared boundary and over 6 metres to the property itself, due to this separation distance it is not considered that the proposed rear extension would have a detrimental impact on the residential amenities of this neighbour. All other neighbours are sufficiently separated from the proposed rear extension for there to be a detrimental impact. The changes to the fenestration include the removal of an existing window on the side elevation, facing 12 Bedford Avenue, and the insertion of two new windows on this elevation. Due to the presence of the existing window in a similar position to the two proposed, they are not considered to have a significant impact on the privacy of this neighbouring property to warrant refusal. Overall, the proposal is considered to have an acceptable neighbour amenity impact, complying with Section 12 of the NPPF, Policy HQ1 of the Central Bedfordshire Local Plan and Section 11 of Central Bedfordshire Design Guide 2023. The proposal would not lead to any additional bedrooms or the removal of any onsite parking, therefore, sufficient off-street parking has been retained onsite. As such, the proposal is considered to be in conformity with Policies T2 and T3 of the Central Bedfordshire Local Plan. Silsoe Parish Council were consulted as part of this application, but no comments were received. The application was also subject to a public consultation, and no comments were received.
