Officer report

What officers recommended

Officers recommended approval subject to conditions and a GIRAMS unilateral undertaking, concluding the proposal complied with relevant planning policies.

“The design is considered to be acceptable and accord with the requirements of Policy DM 1.3, DM 2.4, DM 3.5, DM 3.8, DM 3.12, DM 3.13, DM 4.2 AND DM 4.10 of the SNLP, Policies 2, 3, 5, 6 and 7.2 and of the GNLP and Policies 6, 7, 9, 15 and 16 on the DDNP, and the requirements of the NPPF.”

“Recommendation Authorise the Assistant Director of Planning to approve with conditions, subject to signing of a (GIRAMS) Unilateral Undertaking.”

Officer report

Why officers supported it

Officers considered the revised design would retain open space, fit the surroundings, protect heritage and views, and avoid unacceptable amenity or highway impacts.

“Throughout the application process, the proposed scheme has been revised to reduce the scale of the proposed building to create a scheme that is now considered to sit effectively on the bank of the Mere. The substantial bulk and form of the proposed dwelling is located on the section of land outside of the defined ‘Local Green Space’.”

“As highlighted above, the scheme in discussion with the Councils Design and Conservation Officer has been revised insofar as the overall scale of the dwelling has now been reduced. It is considered that the scheme now offers an effective means of understanding its relationships with its surroundings. The Design Officer stated:”

Officer report

Objections received

The town council and four representations objected over open space, scale, access, parking, flooding, archaeology, views and private green space.

“Site is part of ‘Designated Green Space’ in the Diss and District Neighbourhood Plan. • Unacceptable scale of development in Conservation Area. • Vehicle access and parking are inadequate • Area designated where “new buildings are inappropriate development” • Lack of access to private green space for existing development.”
