About this application

This is a planning application at 15 St James Villas Winchester Hampshire SO23 9SN. Winchester has handled 4,735 applications of this type. This one was decided in 305 days, 36 weeks longer than Winchester's typical decision time. The site is in the Winchester conservation area, with 6 listed buildings nearby. There has been 1 other application at this address. We hold 617 applications in total for the SO23 postcode area.

Why it was refused

  1. The proposal would fail to preserve the building's special architectural and historic interest, and the limited private benefit arising from the provision of additional accommodation would not outweigh the identified harm. The development is therefore contrary to Sections 16 and 66 of the Planning (Listed Buildings and Conservation Areas) Act 1990, Policies HE3, HE5 and HE8 of the Local Plan 2020-2040, and Policies HE5 and HE6 of the National Planning Policy Framework (2026). Corporate Head of Planning and Regulatory Services.

From the council's decision notice.
