Why it was refused

  1. Due to drawing errors and insufficient details the application results in an unacceptable level of uncertainty and potential harm to the significance of the Grade Il listed building and therefore fails to comply with policies EN1 of the Hastings Local Plan - Planning Strategy 2014, HN1 of the Hastings Local Plan - Development Management Plan 2015 and Paragraph 212 of the National Planning Policy Framework.

From the council's decision notice.
