Three Chalet Bungalows Refused — Backland Green Space and Neighbour Amenity, Burnham-on-Crouch

The Application

The application sought permission for three chalet bungalows with associated parking on backland off Mangapp Chase, Burnham-on-Crouch. The site was the residual southern portion of a larger plot that had already been granted permission for five dwellings. The earlier approved layout had deliberately left this part of the land undeveloped as green space, together with part of an adjoining rear garden that the applicant had since acquired to enlarge the plot.

The Client's Concern

The client, a neighbouring resident whose garden backs onto the site, had already watched the mature trees on this land felled in March 2023, shortly after work began on the approved five-house scheme. These were trees that sat outside the footprint of the approved houses, and a complaint to the Council's enforcement team found no breach. When a further three dwellings were proposed on exactly that cleared land, the client asked Planning Voice for a professional objection that would set out the planning history and the harm clearly.

Our Objection

1. Harmful Backland Development and Loss of Green Space

We set out how the earlier permission had been structured around keeping this southern parcel open to retain trees, screen the development and maintain visual breathing space between the rear gardens of Mangapp Chase and Barnmead Way. The new proposal sought to undo that structured approach. With no street frontage and an insular, rear-facing layout, the bungalows would sever the green corridor and consolidate a block of built form against the rear of Barnmead Way. This conflicted with Policy D1 of the Maldon District Local Development Plan (responding positively to local character, layout and landscape setting), Policy H4 (design-led development avoiding overdevelopment) and Policy HO.8 of the Burnham-on-Crouch Neighbourhood Plan.

2. Ecology, Tree Loss and Biodiversity

The trees felled in March 2023 had been identified in the original arboricultural documents and formed part of the justification for limiting the earlier scheme to five houses. We argued that the new application sought to capitalise on their absence, proposing development that would never have been acceptable had that green infrastructure remained. The applicant's own Biodiversity Net Gain metric recorded an 88.28% net loss in habitat units, far short of the 10% net gain expected under the Environment Act 2021. This placed the scheme in direct conflict with Policy N2, which requires development to conserve and enhance the natural environment and deliver measurable net gains.

3. Overlooking and Loss of Amenity

Chalet bungalows rely on upper-floor dormer windows. At such close separation to the Barnmead Way boundary, those dormers would look directly into neighbouring rear gardens and windows, while the steep roof forms would appear dominant and overbearing from the gardens behind. We set out the resulting loss of privacy, outlook and tranquillity against the amenity requirements of Policy D1.

4. Access, Servicing and Precedent

All three homes would be served from a narrow private drive off Mangapp Chase that was only ever intended for a limited number of properties, with no footways, no clear turning head and no demonstrated arrangement for refuse or fire appliance access at the far end of the drive, contrary to Policies D1 and T2. We also highlighted the precedent: the approved five-house scheme represented a complete development of the site, and allowing further homes in its residual space would invite the incremental erosion of green backland that had been consciously left open.
