1. 1.Colchester City Local Plan 2017-2033 Section 1 Policy SP7 requires development to achieve high standards of urban and architectural design and to respond positively to local character and context in order to preserve and enhance the quality of existing places and their surroundings. Colchester City Local Plan 2017-2033 Section 2 Policies DM13 and DM15 require domestic extensions to be compatible with the scale, appearance and character of the original dwelling, avoid overdevelopment and remain subordinate to the host dwelling. Development is also required to respond positively to the character of the site, its context and surroundings with particular regard to height, scale, form, massing and proportions. Policy DP3 of the National Planning Policy Framework (2026) similarly requires development proposals to respond to the history, character and features of their site and setting so that they integrate with and enhance their surroundings. The Essex Design Guide advises that where buildings comprise a combination of forms there should remain a principal element to which subsidiary elements are added. IMPORTANT – ATTENTION IS DRAWN TO THE NOTES ATTACHED DC1001MWD The proposed development, by reason of its cumulative scale, footprint, massing and proportions, would result in an excessive and disproportionate enlargement of the original dwelling. In particular, the two-storey side extension would form a large component of the resultant building rather than appearing as a clearly secondary and subordinate addition. When considered together, the proposal would significantly increase the overall built form and would result in an overdeveloped appearance. The original dwelling would no longer retain clear visual dominance over the proposed extensions. Furthermore, the proposal would materially alter the established proportions of No.1 in relation to No.2 and would weaken the simple composition and visual balance of the existing semi-detached pair. The cumulative extent of the additions would therefore detract form the character and appearance of the host dwelling and would fail to maintain an appropriate visual hierarchy between the original and the proposed development. In addition, the site occupies a prominent and relatively exposed corner position within an open setting. The enlarged form and massing of the dwelling would therefore be readily appreciable within the surrounding area and would appear unduly prominent and out of keeping with the more modest scale and character of development within the locality. For these reasons, the development is contrary to the aforementioned national and local policies.
