Summary

The Planning Applications Committee resolved to grant planning permission to the London School of Economics and Political Science (LSE) for the demolition of the existing buildings at 7 Glasshouse Walk and construction of a part 6/part 8/part 10 storey building, subject to planning obligations being secured in a Section 106 legal agreement and conditions. The building will contain a Social Sciences incubator space, light industrial space and halls of residence, with 35% of the student rooms being let at the London Plan definition of an 'affordable rent'.1

Over-Concentration of Student Accommodation

Councillor Scott Ainslie raised concerns that the provision of further student accommodation in Vauxhall, given the number of PBSA schemes already in the area, would lead to an over-concentration of student accommodation. In response, the case officer, Lauren Shallcross, confirmed that the site is located approximately 600 metres from a cluster of PBSA in Miles Street and 550 metres from a scheme under construction at 238 Kennington Lane. Although these sites are in the same ward, Ms Shallcross said that their distance from the site is sufficient to avoid any, in officer's view, any concern of over-concentration of student accommodation. Ms Shallcross also noted that there is substantial intervening development comprising residential and commercial development as well as open space in the vicinity.

Councillor Ainslie also drew attention to Lambeth Local Plan Policy H7 which states that the development will be supportive where it does not compromise capacity to meet the need for conventional dwellings, especially affordable family homes. Ms Shallcross responded by explaining that although originally sought to restrict all additional student housing development in Vauxhall, this was rejected by the inspector during the Local Plan examination. This was because such a restriction would conflict with the London Plan's aim of encouraging student housing in areas with good access to education institutions and public transport. The inspector did, however, accept a restriction on student housing in the Miles Street area due to the high concentration of student accommodation in that location.

Geoff Holt, Deputy Head of Strategic Applications, added that the site is not allocated for housing, is not part of the housing trajectory and there has never been a planning permission for residential use. He concluded that this scheme just happens to meet the policy and it doesn't fulfil that test of restricting development that could otherwise provide conventional housing. Councillor Ainslie asked that it be minuted that the Committee remains mindful of the need to provide more conventional housing, especially affordable family housing.

Affordable Accommodation

Councillor Ainslie asked how affordable accommodation is allocated, and how that allocation is made. Ian Spencer, Director of Residential Services at the LSE, explained that the LSE attempts to offer affordable accommodation to undergraduate students in need because they are the only students for whom the LSE is able to obtain income details. Graduate student income is unknown, so it is more difficult to assess need.

Councillor Ainslie then asked for more information about the difference between the standard of affordable rooms and market rate rooms. Mr Spencer explained that the rooms are the same standard, but that the LSE's strategy is to provide all student accommodation at sub-market rents.

Daylight & Sunlight

Councillor Ainslie also raised concerns about the impact of the development on daylight and sunlight for neighbouring properties, particularly those that are already subject to a 'tunnel effect' because of existing projections. Giulio Antonuto of Arup, the applicant's daylight & sunlight consultant, explained that the assessment methodology compares existing to proposed conditions, with a change of less than 20% considered to be imperceptible. However, in dense urban locations where it is impossible to maintain existing levels of daylight and sunlight, residual values need to be assessed instead, with values of between 10% and 20% Vertical Sky Component (VSC) considered to be typical of city centre locations.

Mr Antonuto explained that the 'tunnel effect' describes the situation in which receptors experience significantly reduced daylight and sunlight as a result of existing projections flanking windows. He confirmed that the assessment had taken this existing reduction into account when calculating the percentage change.

Sustainable Design & Construction

Councillor Ainslie enquired about the carbon footprint of demolishing and rebuilding the existing buildings, asking what consideration had been given to retrofitting them instead. Ms Shallcross replied that a pre-demolition audit undertaken as part of the Circular Economy Statement had concluded that the buildings are not fit for reuse because they have limited load capacity, poor insulation, inefficient equipment, and problems with access and emergency routes. She also said that it is estimated that 99% of demolition products will be either reused or recycled.

Councillor Ainslie then sought clarification on the extent of demolition. Ms Shallcross confirmed that the existing buildings will be demolished in their entirety, and that a basement will be constructed as part of the proposals.

Councillor Ainslie also raised the issue that the proposals fall short of the London Plan's 35% on-site carbon reduction target, achieving 22% instead. Erland Hulin of Blewburton, the applicant's energy & sustainability consultant, explained that when Part L of Building Regulations was revised in 2021, the baseline for commercial buildings was adjusted to include low carbon heating, but the baseline for residential buildings was not. This means that it is more difficult to achieve significant carbon reductions for commercial buildings. However, Mr Hulin confirmed that the building incorporates passive design, air-source heat pumps, ventilation with heat recovery, and waste water heat recovery.

Mr Hulin also said that although the site is in a heat network priority area, it is not close enough to any existing networks to be connected. However, the building is designed to be easily connected to a district heating network if one becomes available in the future, and a carbon offset payment will be secured in the Section 106 legal agreement to mitigate the carbon emissions shortfall.

Transport

Councillor Diogo Costa highlighted that Lambeth is a living wage borough and requested that this be included in the decision. It was agreed that the applicant would be informed through an informative on the decision notice.

Councillor Costa also questioned the reduction in the Transport for London (TfL) contribution from £550,000 to £300,000. Ms Shallcross explained that the reduction is a consequence of Lambeth Council securing a £250,000 contribution for Healthy Routes and Neighbourhood Regeneration. Simon Phillips, Assistant Director, Climate Change and Strategic Transport, explained that the original contribution requested by TfL was to support the Lambeth Bridge scheme, but that this scheme is fully funded by TfL. The £250,000 contribution to Lambeth Council will instead be used to trial a Healthy Neighbourhood scheme in the area.

Councillor Ainslie queried whether it would be possible to use the transport contribution to fund an active travel route from Vauxhall to Waterloo Bridge. Mr Phillips responded that it is not possible to ask a single developer to fund a whole piece of infrastructure, and that this funding is more appropriately used to improve the area local to the site. He also confirmed that there are separate schemes underway to improve routes in Waterloo.

Councillor Bailey expressed concerns about the impact of food delivery trips from the student accommodation. Mr Phillips confirmed that although these trips are difficult to quantify, the applicant has estimated that there could be as many as 100 food delivery trips per day. He said that this should be accommodated by the 2 spaces available in the loading bay, as well as the provision of short-stay cycle parking.

Decision

Councillor Martin Bailey proposed that the officer's recommendation to grant planning permission be approved, subject to the inclusion of an informative on the decision notice informing the applicant that Lambeth is a living wage borough. This was seconded by Councillor Diogo Costa. The proposal was carried with 3 votes in favour and no objections, and 1 abstention from Councillor Ainslie.


  1. According to the London Plan, affordable student accommodation is defined as accommodation let at a rental cost for the academic year equal to or below 55% of the maximum income that a new full-time student studying in London and living away from home could receive from the Government’s maintenance loan for living costs for that academic year.
