Officer report

The site and surroundings

The site forms part of a rear garden and outbuilding facing Devonport Gardens in a residential area, beside homes on three sides.

“The surrounding area is residential in character with a variety of styles along Wanstead Lane and Devonport Gardens, comprising a mixture of pairs of two-storey semi-detached properties and rows of two storey terraces with gable front features and bay windows with hipped or gable roof forms. The site shares a common boundary with residential properties no. Devonport Gardens to the north and no. Wanstead Lane to the west.”

“No. Wanstead Lane (which forms a pair with the application site) is located west of the application site and shares side boundary with the application site. No. 78 benefits from a hardstanding area with canopy/veranda style cover over located in its rear garden adjacent to the existing outbuilding subject of the application before you.”

Officer report

Why officers supported it

Officers considered the proposal effective housing use with acceptable design, accommodation, transport arrangements and effects on neighbouring homes.

“The proposal would make an effective use of the rear of the site, and would contribute housing stock within the borough without compromising amenity of the neighbouring residents.”

Officer report

Residents’ objections

Residents objected that the scheme would harm character, garden land, light, outlook and privacy, increase disturbance and worsen parking.

“The proposal represents loss of land that should be retained as private domestic garden space; whilst the applicant states the garden is fully hard-surfaced, the land remains designated This matter is discussed below under section 17. In summary, there is no requirement for BNG here as the proposal is exempt. Furthermore, in this instance, the…”

“Increase in parking stress and congestion. The submitted Parking Stress Survey has recorded the average parking stress during peak evening hours, but not provided a stress survey for peak daytime hours. The surrounding streets are already heavily congested during the day with commuters parking their cars.”

Officer report

Consultation responses

Highways raised no objection, Natural England accepted mitigation subject to assessment, and environmental health identified no contamination condition.

“Providing the appropriate assessment concludes that the measures can be secured, it is likely that Natural England will be satisfied that there will be no adverse effect on the integrity of the European Site(s) (habitats site(s)) in relation to recreational disturbance. An appropriate Habitat Regulation Assessment (HRA) has been carried out.”

“Environmental Health (Contamination Lead) Comments that the site does not have any former contaminative land-uses. No land contamination condition will be required for this proposed development.”

Officer report

Effects on neighbours

The proposed building would project beyond a neighbouring bay window, but officers found no unacceptable effects on light, outlook, privacy, noise or disturbance.

“Whilst all development will have some impact in terms of light, officers have carried out a 45-degree light test which demonstrates that the bay window at no. 1 will not be unduly affected by the extended building (height and depth). Similarly, whilst there would be a degree of impact on outlook, it would not be to such an extend as to justify refusal given the width of the bay window..”

“Given the above, there will be no unacceptable impact to no. 78 terms outlook, increased sense of enclosure, privacy, light, or noise and disturbance. The Google image below shows the site in relation to no. Wanstead Lane and No. Devonport Gardens:”
