The LSA Award 2026 Winner: Caspar Barker

The 2026 LSA Award winner is Caspar Barker for ‘Unplanning Suburbia: Unlocking An Alternative Future For London’s Metroland’ (MArch Designing Architecture thesis project).

Why this project was selected:

This project was chosen for the inaugural LSA award in recognition of its ambition to challenge aspirations and expectations regarding typology, policy and collective life within a suburban context. This is a context often ignored by architects and contemporary architecture as a strategic imperative or as a site of critical enquiry and interrogation.

Casper’s project provides an architectural solution that addresses issues of accessibility and affordability in relation to housing in London and potentially other large cities where communities, and in particular families, are being forced to relocate. The proposal is inherently sustainable; socially, culturally and economically as well as environmentally.

Not only does the project propose an innovative, ambitious and progressive architectural response to the potential densification of the suburban condition, it also suggests the policy and systemic infrastructure that would be required to achieve that outcome. Whether it’s research, architectural design or policy; every output produced has been executed to an exceptionally high standard of visual communication ensuring that ideas as well as architecture are legible and accessible.

The LSA Award is intended to spotlight a project that most represents the mission, intent and purpose of the LSA.

About the project:

With London’s Population projected to grow to over 11 million by 2050 when London’s remaining major brownfield development sites have all been completed, alternative approaches to building new homes in the capital are going to be required. My thesis stands in direct opposition to the Labour Governments 2024 planning reforms to permit development on select greenbelt land and instead I would like to confront how planning reform might bring opportunities for mutually beneficial development among the London’s vast low density suburban neighbourhoods to counter urban sprawl.

Inspired by the absence of planning controls which characterised England’s early 20th century ‘plotland’ settlements as well as more contemporary examples such as Oosterwold, Almere in the Netherlands this thesis explores how planning freedom could unlock an alternative future for London’s suburbs. The proposed strategy involves local authorities allocating ‘permitted development zones’ in low density suburban areas, where any development is permitted provided defined conditions are met. In this case a percentage distribution of uses must be achieved across the site area and the population density of the site must be doubled to qualify for these freedoms. The policy promotes individual and innovative design responses whilst the set conditions ensure effective densification of London’s suburban neighbourhoods alongside delivering missing amenity and diversity.

The proposed policy is tested in the context of the Northwick Park Estate located in Kenton on the border of Harrow and Brent. The area is emblematic of the monofunctional Metroland suburbs, an expansive area of early 20th century development tracing the metropolitan railway line.
