The Planning Sub-Committee (2) is scheduled to consider three planning applications at its upcoming meeting. The applications involve proposals for roof extensions, the amalgamation of residential units, and external alterations to a property.

118 to 258 Lauderdale Mansions, Lauderdale Road, London, W9 1NG

A significant portion of the report pack is dedicated to a proposal for roof extensions at 118 to 258 Lauderdale Mansions. The application seeks permission for the erection of roof extensions, the creation of associated rear terraces and fire escapes, and the installation of lifts and lantern roof lights within existing lightwells. These works are intended to create four new two-bedroom residential units.

The report details extensive public consultation, with numerous objections received concerning land use, design, amenity, highways, and sustainability. Key considerations include the impact on the Maida Vale Conservation Area, the quality of the proposed accommodation, and the potential for increased pressure on local services. The report notes that previous applications for roof extensions at this site have been refused and dismissed at appeal, with reasons including failure to optimise the number of residential units, poor quality of accommodation, and detrimental design impact on the conservation area. The current application aims to address these previous concerns.

The proposal includes a payment in lieu for affordable housing, estimated at £437,800, and the installation of Air Source Heat Pumps and solar panels. The report discusses the potential impact on daylight and sunlight for existing residents, as well as concerns regarding noise and vibration from the proposed lifts and Air Source Heat Pumps. The report also addresses highway impact, with the provision of cycle parking and a legal agreement to prevent future residents from obtaining parking permits.

3 Fulton Mews, London, W2 3TY

The committee is also scheduled to consider an application for 3 Fulton Mews. This proposal involves the amalgamation of two existing self-contained residential apartments into a single-family mews house. The plans also include the conversion of a garage into habitable space and alterations to the fenestration.

The report highlights that the proposal would result in the loss of a residential unit, which is contrary to Westminster's City Plan Policy 12 and the London Plan. While the applicant argues that the unit to be lost is substandard and the amalgamation would create a high-quality family home, officers note that the existing larger flat is already considered family-sized. The report also addresses concerns regarding the design of the proposed alterations, particularly the removal of traditional garage doors and their replacement with windows, which is considered to harm the character and appearance of the Bayswater Conservation Area.

74 Eccleston Square Mews, London, SW1V 1QN

The final planning application to be discussed concerns 74 Eccleston Square Mews. This application, made on behalf of Councillor Mark Shearer, seeks permission for external alterations, including the replacement and insertion of windows to both the Eccleston Square Mews and Belgrave Road frontages.

The report indicates that the proposed works are limited in scope and are considered to be consistent with the surrounding architectural context. The alterations are expected to have a neutral impact on the character and appearance of the Pimlico Conservation Area. The report details the proposed changes to the fenestration on both elevations, noting that while traditional garage doors are a characteristic of mews properties, the existing door at this property is of modern construction, and there is no consistent pattern of traditional garage doors along Eccleston Square Mews. The proposed replacement windows on the Eccleston Square Mews elevation will include timber panelling beneath, which is intended to maintain the established architectural language of the mews. The report concludes that the proposals are acceptable in terms of land use, design, heritage impact, and residential amenity.
