Permission to demolish the rear porch and construct a corridor to the rear of the house. Retention to retain the existing single storey structure in the rear garden and use it as a bedroom and en-suite, which will be linked to the existing house with the proposed corridor, all with associated site works.

Refused

Core Refusal Reason

The applicant failed to demonstrate a 'genuine need' for a family flat as the intended occupant (a cousin) is not considered an immediate family member, and the proposed design was found to be poor, resulting in a fragmented residential unit and a suboptimal subdivision of private garden space.

Decision Maker's Conclusion

  • The proposed development fails to meet the 'genuine need' criteria for family flats under Section 12.6.8 of the Development Plan, as a cousin is not defined as an immediate family member.

  • The physical arrangement would permanently bisect and subdivide the rear garden, resulting in poor usability and a loss of quality private amenity space for the occupants.
