Exclusive: The London Tenants Federation (LTF) has criticised the reliance on market-driven housing models to fund social homes, as Lewisham Council approves a major long-term strategic partnership aimed at accelerating affordable housing delivery across the borough.
While the local authority confirmed the appointment of a preferred development partner to govern municipal housing initiatives for at least the next decade, tenant advocates argue that cross-subsidising social housing through private market sales remains a "failed model."
Pat Turnbull, Regional Delegate for the London Tenants Federation, highlighted the urgent need for direct government funding for council homes to address London's escalating housing crisis.
“LTF says the evidence proves that funding the building of social rent homes by cross subsidising from building private homes for sale is a failed model,” said Pat Turnbull, Regional Delegate for the London Tenants Federation.
“Year after year London exceeds its planned figures for market homes and hugely under-achieves on building social rent homes. Only government funding, which we would prefer to see given to councils directly to build council social rent housing, can start to meet the great need for social rented homes.
“And social rented homes are the only kind that meet the need for affordability and security so desperately required by all the households on council waiting lists, in temporary accommodation, in overcrowded housing, or on the streets.”
The new strategy moves local housebuilding away from the traditional developer-led model, giving the local authority greater control over the quality, sustainability, and affordability of new estates. The partnership covers an initial 10-year operational period, with a built-in contractual option to extend the terms for a further five years. Council officers are legally restricted from disclosing the specific identity of the corporate partner until the statutory call-in period concludes in mid-July 2026.
Once legal clearance finishes, a new Strategic Development Partnership Board will be established to oversee financial performance, project timelines, and local procurement targets across the affected wards.
The local authority has designated two major active regeneration areas as the inaugural projects to be handled through the joint framework. In the Catford South ward, the Thomas Lane Yard development will transform a former central car park and light industrial site into two brick structures reaching eight and 12 storeys high. The development will introduce 113 affordable homes, allocating 39 units for social rent and 74 units for shared ownership alongside new commercial spaces.
In the Deptford ward, the first phases of the Achilles Street Estate regeneration will move forward under the same partnership mechanism. The long-debated New Cross project will ultimately replace older council blocks to deliver 278 high-quality homes, including 122 dedicated specifically to social rent.
The implementation of the partnership comes as the local authority attempts to manage severe structural demands on its housing registry. Current data shows that Lewisham faces an acute housing shortage, with over 10,500 households waiting for permanent accommodation and 2,450 families currently placed in temporary housing.
By involving partners earlier in the planning and design processes, the council aims to remove the requirement for individual procurement rounds on every future site. London-wide trends show councils are increasingly turning to joint-venture delivery models to navigate post-pandemic construction inflation and high borrowing costs. Under this framework, projects can progress on council-owned land while ensuring the local authority retains first refusal on all completed affordable housing units.
