Planning Objections in London

Planning Policy in London

London applications must comply with both the borough’s adopted Local Plan and the London Plan 2021 — the Mayor’s strategic planning framework. The London Plan sets policies on housing quality, design standards, heritage, daylight and sunlight, and density, including Policy D3 (optimising site capacity), Policy D6 (housing quality and standards), and Policy HC1 (heritage conservation and growth). Understanding how these interact with borough-level policies is essential to preparing an effective objection, and it is something we do on every London case. The NPPF also applies as the overarching national framework.

Heritage considerations are pervasive across the capital, with thousands of listed buildings and hundreds of conservation areas, many subject to detailed Character Appraisals. The 45-degree rule and BRE daylight guidance are consistently applied by London planning authorities, and several boroughs operate Article 4 Directions requiring full planning permission for HMO conversions in areas of high concentration.

Experience in London

Planning Voice has prepared objection letters across a wide range of London boroughs, including Barnet, Southwark, Croydon, Lambeth, Greenwich, Enfield, Bromley, Hammersmith and Fulham, Hackney, Lewisham, Merton, Brent, Haringey, Hounslow, Camden, Redbridge, Waltham Forest, Ealing, Hillingdon, Bexley, and Tower Hamlets. Our work in London has addressed residential extensions, loss of light, overdevelopment, heritage harm, HMO concentration, and basement excavations. In each case, we have grounded our objections in the relevant borough Local Plan, the London Plan 2021, and the NPPF.

In Barnet, we objected to a single-storey side extension and garage conversion on a residential cul-de-sac. Our objection argued that the extension would create a narrow, enclosed passage along the adjacent driveway, resulting in an overbearing and claustrophobic impact on neighbouring amenity, while the loss of the garage would eliminate a usable off-street parking space and restrict vehicle manoeuvrability on an already constrained plot. We engaged Barnet’s Local Plan amenity policies and the borough’s design guidance on character and streetscene.

In Greenwich, we objected to the change of use of a dwelling to a five-bedroom HMO combined with a rear extension, loft conversion and rear dormer within a terrace of Victorian properties. Our objection raised the cumulative noise and disturbance associated with intensified occupation in a property with no soundproofing, the loss of light to adjoining neighbours from the deep rear extension on a narrow terraced plot, and the failure to provide adequate living conditions for future occupants, including bathrooms without natural light or ventilation. We deployed the Royal Borough’s Policy DH(b) on protection of amenity for adjacent occupiers.

In Lambeth, we objected to a roof extension and roof lift within the Waterloo Conservation Area. Our objection argued that the intensification of the site would generate unacceptable levels of noise disturbance, that the introduction of a roof terrace and additional windows would cause a severe loss of privacy to neighbouring properties at a separation distance of only 1.2 metres, and that the scale and design of the roof extension would cause harm to the conservation area, contrary to Lambeth’s Policy Q2 and Policy Q22 on the historic environment.

In Croydon, we objected to the conversion of a semi-detached family dwelling to a six-bedroom HMO with garage conversion, in a quiet residential area with low public transport accessibility. Our objection engaged Croydon’s Local Plan policies on design and character, arguing that the proposal would result in the loss of a much-needed family home in an area of high demand, introduce transient occupation patterns incompatible with the established residential character, and exacerbate parking pressures on a street where on-street capacity was already under strain.

In Southwark, we objected to rear and loft extensions on the grounds of loss of daylight and sunlight to neighbouring habitable rooms, and in separate cases raised arguments about the harm to heritage assets including impacts on the setting of listed buildings and the character of conservation areas. In Enfield, we objected to a loft conversion and new dwelling on the grounds of loss of light to adjacent properties. Across Hammersmith and Fulham, we have prepared multiple objections to rear extensions, loft conversions, and demolition proposals, consistently engaging the borough’s heritage and amenity policies where sites fell within or adjacent to conservation areas.
