Scheme description

Alterations including erection of extension above two-storey back addition and erection of single-storey rear/side extension.

Why it was refused
Reason 1

The proposed roof extension, as a result of its design and form, would be an incongruous and unduly bulky addition, detrimental to the character and appearance of the host property, and out of keeping with the surrounding context. The proposal would therefore fail to accord with policies LP1 and LP5 of the Local Plan (2023) and the Housing SPD (2016). In dealing with this application the Council has implemented the requirement in the National Planning Policy Framework to work with the applicant in a positive and proactive manner and the Council has, as far as practicable, sought solutions to problems arising in relation to dealing with the planning application. We have made available detailed advice in the form of our statutory policies in the Local Plan consisting of the Core Strategy, Development Management Policies Document, Supplementary Planning documents and where appropriate the Site Specific Allocations Document as well as offering a full pre application advice service, in order to ensure that the applicant has been given every opportunity to submit an application which is likely to be considered favourably. In addition further guidance was offered to the applicant by the case officer during the processing of the application to identify amendments to address those elements of the scheme considered unacceptable. However, the necessary amendments to make the application acceptable are substantial and would materially change the development proposal. They would require further consultations to be undertaken prior to determination, which could not take place within the statutory determination period specified by the Department of Communities and Local Government. You are therefore encouraged to consider submission of a fresh application incorporating the material amendments set out below which are necessary to make the scheme acceptable. Required amendments: Form a mansard extension above the back addition with 70-degree slopes to the side and rear.
