Major South London Development Sparks Outrage Over Affordable Housing Cuts
The developer behind a controversial housing project in Elephant and Castle is facing significant backlash after proposing to drastically reduce its affordable housing commitment. Berkeley, the company responsible for the Borough Triangle development, has submitted a Section 73 planning application that would see affordable homes slashed from 35 percent to just 10 percent overall.
Developer's Conditional Offer
A Berkeley spokesperson told the Local Democracy Reporting Service that the company aims to deliver 20 percent affordable housing, but only if it can access grant funding through the Government and Greater London Authority's new planning route. This route allows developers delivering at least 20 percent affordable housing to apply for grants on all units above the first 10 percent without needing additional viability assessments, provided planning decisions are issued by March 31, 2028.
The current proposal would provide a minimum of 60 affordable homes, consisting of 42 social rent and 18 intermediate homes. This represents a dramatic reduction from the originally approved scheme, which included 230 affordable homes (35 percent) within the 892-home development.
Development Details and Local Impact
The Borough Triangle development consists of four tower blocks, with the two tallest buildings reaching 38 and 44 storeys respectively. The plans include:
- 892 total homes across four towers
- An office block and flexible café or retail space
- A new community center expected to be occupied by a Latin American group
- 1,780 square meters of public space
- A replacement food hall for the current Mercato Metropolitano
The development requires demolition of several buildings, including the popular Elephant and Castle branch of Mercato Metropolitano, which will remain open until the end of 2026. During construction, up to 12 traders will be temporarily relocated to a nearby location by Berkeley, while most of the 40 traders will need to find alternative arrangements.
Political Backlash and Community Concerns
The revised plans have already faced strong opposition from both Liberal Democrat and Labour groups in Southwark. Councillor Victor Chamberlain, Liberal Democrat Leader of the Opposition at Southwark Council, stated: "This scheme was already failing local people - now it's getting even worse. Cutting affordable housing to just 10 percent on a site delivering nearly 900 homes is simply unacceptable."
Councillor Graham Neale, ward councillor for St George's ward, added: "Residents have been clear all along - this development does not deliver the homes local people need. Southwark is in the middle of a housing crisis. We should be maximizing genuinely affordable homes on sites like this, not allowing them to be cut back."
Southwark Labour has also spoken out against the reduction. Councillor Helen Dennis, Southwark Labour spokesperson for New Homes and Sustainable Development, called the 10 percent offer "immensely disappointing" and stated: "For a development of this scale in a prime central London location to be reduced from 35 percent affordable to just 10 percent is unacceptable and simply cannot be justified."
Developer's Defense and Viability Challenges
Berkeley has cited viability challenges at the Borough Triangle site, including changes to fire safety regulations, as reasons for the reduced affordable housing offer. The company claims there are no other "tenable options" to reduce development costs.
A Berkeley spokesperson explained: "The reality is that each affordable home is built at a major financial loss, so developments can't deliver as many now that taxes, planning levies, regulations and build costs have all increased. This is why new private and affordable homebuilding has fallen to record lows across London."
The spokesperson emphasized the broader benefits of the project, including much-needed private and affordable homes, major new investment in community infrastructure and local services, a new community space, public square, 60 apprenticeships, and hundreds of jobs.
Planning History and Wider Context
The original scheme was narrowly approved by Southwark councillors by 4 to 3 votes in 2025, facing strong opposition with 415 out of 434 public comments being objections. Liberal Democrat councillors have now contacted Southwark Council's Head of Planning, urging officers to refuse the Section 73 application, arguing it would set "a dangerous precedent" and further erode trust in the planning system.
This controversy comes as Berkeley is also involved in the redevelopment of the Aylesham Centre in Peckham, another controversial regeneration scheme that could see affordable housing drop from 35 percent to just 12 percent. Those proposals are currently awaiting an outcome from the Planning Inspectorate after Berkeley appealed due to not receiving an update from Southwark Council on its revised application.
The Borough Triangle development represents a significant test case for affordable housing delivery in London, with implications for how developers and local authorities balance viability concerns against the urgent need for genuinely affordable homes in the capital's ongoing housing crisis.
