The Planning Sub-Committee (2) of Westminster Council met on Tuesday 23 June 2026 to discuss three planning applications. The committee refused an application for roof extensions at 118-258 Lauderdale Mansions, approved the amalgamation of two apartments into a single mews house at 3 Fulton Mews, and granted conditional permission for external alterations to a property at 74 Eccleston Square Mews.

The committee refused an application for the erection of roof extensions, associated rear terraces and fire escapes, installation of lifts and lantern roof lights to lightwells, and the installation of rooflights, Air Source Heat Pumps, and Photovoltaic Solar Panels. The proposal aimed to create four self-contained residential units. The refusal was based on the visible fire escape stairs, which were deemed to harm the appearance of the building and fail to preserve or enhance the character and appearance of the Maida Vale Conservation Area. This decision aligns with Policies 42, 44, and 45 of the City Plan 2019-2040.

The committee unanimously approved an application for the amalgamation of two existing self-contained residential apartments to form a single-family mews house, including the conversion of the garage into a habitable room and alterations to fenestrations. The reason for approval was that the proposed amalgamation would create a superior family home, justifying the loss of a small, cramped unit that would be better incorporated into the larger dwelling. The physical changes to the building were not considered sufficiently harmful to warrant refusal. However, the officer's report had recommended refusal on the grounds of land use, specifically the loss of a residential unit, contrary to Policy 12 of Westminster's City Plan and Policies H1 and H2 of the London Plan. The report also noted that the proposed alterations to the front elevation, including the removal of the garage door and its replacement with a window, would harm the character and appearance of the Bayswater Conservation Area. Despite the officer's recommendation, the committee approved the application, with Councillor Stephenson-Oliver expressing disagreement with the officer's recommendation and supporting the amalgamation.

Conditional permission was unanimously granted for external alterations, including the replacement and insertion of windows, at 74 Eccleston Square Mews. The application was made on behalf of Councillor Mark Shearer. The proposed works were considered to be limited in nature and consistent with the surrounding architectural context, therefore having a neutral impact on the character and appearance of the Pimlico Conservation Area. The decision aligns with City Plan Policy 16 (Housing Quality) and London Plan Policy D6 (Housing Quality and Standards).
