Conversion of one-bedroom house into two one-bedroom flats. Demolition of single storey rear extension and erection of part single storey/part two storey rear extension. Internal alterations.
The proposed accommodation would fail to comply with the minimum internal space standards in terms of internal floor space and built in storage space for a single-storey 1-bed, 2-person unit, as set out in Table 3.1 of Policy D6 of the London Plan 2021.
The applicant has failed to demonstrate through the submission of cogent information that the proposed 1st floor rear extension would not have an unacceptable adverse impact on the closest principal habitable room windows at No. 95 Mount Road in terms of daylight/sunlight. Given the scale of the extension and the proximity of neighbouring windows it is considered that there is a likelihood that the development would breach the "BRE 25 Degree Rule" and reduce light entering into the neighbouring dining room, which in turn would harm the residential amenities of the occupant of the neighbouring property. As such, the proposal is therefore contrary to policy D3 of the London Plan 2021 and policy DM10 of the LDF Core Strategy 2012.
