Two-Storey House on a Corner Side Garden Refused — Overdevelopment and Street Character, Chelmsford

The Application

The application sought permission for a two-storey detached house, with an extended vehicular crossover, two parking spaces, bin and cycle stores and new boundary fencing, on the side garden of a semi-detached house at the corner of Storms Way and Brook End Road, Chelmer Village. Earlier in the year the Council had already approved a part single-storey, part two-storey side and rear extension to the same house, and that extension was under construction. The new dwelling would take the remaining side garden, including the garage and the parking spaces that served the existing house.

The Client's Concern

The client, a neighbouring resident who had already objected to the extension, was concerned that a second, separate house on what was originally the plot of one modest semi-detached home would close the open corner and leave the street looking cramped. Amended plans were uploaded part-way through the consultation, so the client asked Planning Voice to review the full set of drawings, including the revisions, and prepare a policy-based objection.

Our Objection

1. Overdevelopment and Loss of the Open Corner

Policy DM23 of the Chelmsford Local Plan (2020) requires new buildings to respect the character of their surroundings in siting, scale, form and massing. The proposed house was 7.6 metres wide on a plot 7.8 metres wide, leaving only 0.1 metres to the boundary on each side. The roof detailing had been pared back with minimal verges and flush eaves just to keep within the plot. Combined with the approved extension, the original pair, the extension and the new house would read from the street as an almost continuous run of two-storey development, with a gap of little more than a metre between buildings. Storms Way is otherwise characterised by semi-detached houses and bungalows in spacious plots. We relied on the Council's Making Places SPD, which advises that side development should preserve gaps between buildings where these are characteristic of the area, and that timber garden fences should not be used on highway edges such as the proposed 1.8-metre close-boarded fence along Brook End Road.

2. Inaccurate and Incomplete Drawings

The proposed block plan showed the semi-detached pair without the approved extension, understating how much of the plot would be filled with built form. The demolition of the existing garage was not included in the description of development, a drawing listed on the application form had not been published, and the amended plans were uploaded without a drawing schedule. We asked that corrected block plans and contextual elevations be provided, and neighbours re-consulted, before any decision was made.

3. Space Standards and Garden Space

Policy DM26 requires new homes to meet the Nationally Described Space Standards. The room areas labelled on the amended floor plans did not match the dimensions printed on the same drawing, with one bedroom labelled below the single-bedroom minimum, so compliance could not be confirmed. The drawings also gave no indication of how much garden would be left for the existing, extended house once its plot was subdivided.

4. Parking and the Corner Crossover

The two parking spaces that served the existing house were reallocated to the new dwelling, with no demonstration of what parking or cycle storage would remain for the existing home and no visitor parking, contrary to Policy DM27 and the Essex Parking Guidance 2024. The extended crossover across the curved corner of the junction came with no visibility splays or manoeuvring details.
