Two-storey side extension at 21 Whitegates, Northampton

What was proposed

A first-floor side extension would create a two-storey front gable and provide an additional bedroom with en-suite facilities.

“The application proposes a first-floor side extension to the dwelling, forming a two-storey front gable element. The extension would project modestly from the front elevation by approximately 0.5 metres, ensuring it remains subordinate to the host property. The development is intended to provide accommodation for an additional bedroom with en- suite facilities at first-floor level.”

“The proposal has been amended following officer advice. Revisions include alterations to the roof form to a hipped design and a significant reduction in the extent of the rearward projection. These changes ensure that the extension integrates appropriately with the existing dwelling and minimises both visual and residential impacts on the surrounding area.”

What officers recommended

Officers recommended approval because the revised design was subordinate, would not harm neighbours, and provided adequate on-site parking.

“The application site and surrounding street are characterised by individual dwellings set within generous plots, with sufficient spacing and garden areas to the front and rear. Despite the planning history, which includes several related permissions and amendments under references 2024/4019/FUL, 2025/2468/NMA and 2025/3753/S73, the extensions to the dwelling have remained subordinate in nature.”

“On balance and taking into account the revised design and reduced scale of the proposal, the development is not considered to result in significant harm to the…”

Consultation responses

The parish council objected that the property would be too large for the site and street, harming neighbouring privacy and amenity.

“The latest proposal for this property has the overall effect of making the property disproportionately too large for the site and for the existing street…”

Officer report

Residents’ objections

Residents raised concerns about overdevelopment, character, privacy, light, staged future extensions, commercial use and the relationship with earlier proposals.

“Below is a summary of the third party and neighbour responses received at the time of writing this report.”

“Initial concerns still remain • Over development of the property • Is not sympathetic to local character. • Represents poor design that fails to improve the area. • Harms neighbouring amenity. • Fear that approval could enable further staged proposals (e.g. garages or additional extensions), resulting in a much larger scheme than originally refused.”
