Two roof extensions at 1A & 1B Manfred Road, London SW15
Summary of planning committee decision
Decided by Wandsworth Planning Applications Committee on 12 Mar 2026.
What was proposed
Roof extensions would add a floor to both houses, with bedrooms, bathrooms, dressing rooms or studies, dormers and rooflights.
“This application for full planning permission proposes alterations including roof extensions to both properties, creating an additional floor with associated dormers and rooflights.”
“2no. dormers would be installed into the main front roof slope of the proposed roof extension. Each dormer would measure 2.9m in width, 1.9m in depth, 2.0m in height and would have a flat roof. The proposed dormers would be set up from the eaves by 0.8m, set down from the main roof ridge by 0.3m and set in from either side. 1no. 3-pane window would be installed into the front elevation of each dormer.”

Three to four storey detached properties lie to the north of the site, St Stephens Gardens, a one to four storey block of flats lies to the south, three-storey terraced properties to the east and the rear garden of No.14 Oakhill Road is located to the rear/west.”

Officer report
Neighbour concerns
Objections covered privacy, daylight, outlook, noise, overbearing effects, enclosure, visual intrusion, overdevelopment and harm to local character.
“Neighbour Consultation Summary OBJECTIONS: summarised as: • Increase overlooking / loss of privacy due to its scale, height and proximity to surrounding properties • Loss of daylight/sunlight due to its scale, height and proximity to surrounding properties • Loss of outlook • Noise pollution • Close proximity to St Stephens Gardens to the south • Overdevelopment • Unduly overbearing due to its scale and proximity to surrounding properties • Oppressive / Sense of enclosure •…”
Officer report
Agreement and conditions
The legal agreement was intended to ensure both roof extensions were built jointly, alongside conditions on timing, approved drawings and materials.
“Given the nature of the development and its position above the existing flat roof of the two semi-detached properties, it is important that the development is carried out jointly and at the same time to ensure the pair is not visually unbalanced. Only carrying out one half of the development would look awkward, appear out of keeping and would have an adverse impact on the character and appearance of the property and the surrounding conservation area.”
“Details of materials pre commencement No development shall take place until details and samples of materials proposed to be used on all external surfaces of the development shall be submitted to and approved in writing by the local planning authority. The development shall be carried out in accordance with the approved materials and thereafter so retained.”
Officer report
The committee vote
The committee unanimously resolved to grant planning permission subject to a Section 106 legal agreement.
“The Head of Development Management (Wandsworth) noted that although the application was for one development, it comprised of two houses and therefore a S. Legal Agreement was included to ensure that both properties were built as one operation.”
“RESOLVED - (unanimous) that planning permission be granted as set out in the report, noting the additional information as set out in the late items of correspondence paper, subject to S. Legal Agreement.”
