IN Brief:
- L&Q has submitted plans for 772 homes at the former Kodak factory site in Harrow.
- The proposals include garden streets, a civic health centre, commercial space, and 10,000 sq m of public green space.
- The scheme continues the transformation of a major brownfield industrial site into a residential neighbourhood.
L&Q has submitted plans for 772 homes at Harrow’s former Kodak factory site, moving the next major phase of the Portra Rise regeneration scheme into the planning system.
The proposals, designed with Jestico + Whiles, cover a substantial residential phase on the north-west London site. The application has been submitted to the London Borough of Harrow and continues the conversion of the former industrial complex into a mixed-use neighbourhood.
The scheme is arranged around pedestrian-friendly garden streets, with a civic health centre, flexible commercial space, and around 10,000 sq m of accessible public green space. The design draws on the site’s photography and manufacturing heritage while creating a residential quarter structured around public realm, amenity, and local movement.
The former Kodak factory is one of Harrow’s most prominent brownfield regeneration opportunities. Its scale gives the borough a route to significant housing delivery in an established location, although sites of this type bring remediation, infrastructure, planning, phasing, and community expectations that require careful coordination.
London boroughs are continuing to search for deliverable housing capacity on previously developed land, particularly as central sites become more constrained and viability remains under pressure. Outer-London regeneration schemes are therefore carrying more weight, especially where transport access, local services, and land assembly can support higher-density development.
The inclusion of a civic health centre and commercial space gives the proposal a wider neighbourhood function. Large residential schemes are increasingly expected to provide services, active frontages, open space, and local amenities, particularly where development replaces former employment or industrial land. Housing numbers alone rarely carry a major brownfield application through planning without a credible social and infrastructure offer.
Harrow’s recent use of digital twin inspections across borough assets reflects the wider move toward data-led urban management. Growth areas such as the Kodak site will place greater pressure on councils to understand public realm, highways, building condition, access, and maintenance across expanding neighbourhoods.
For the construction supply chain, a 772-home phase would create demand across groundworks, frame systems, façades, roofing, M&E, internal fit-out, landscaping, utilities, highways, health-facility fit-out, and long-term maintenance planning. The delivery challenge will be to sequence those packages so that the site becomes a coherent neighbourhood rather than a collection of separate building plots.
Public realm will need to be planned as a core construction element rather than a late-stage finish. Garden streets and green space require early coordination around drainage, planting, soil build-ups, utilities, lighting, fire access, maintenance routes, and construction logistics. On dense brownfield schemes, landscape quality depends as much on buildability and servicing as on visual design.
The scheme also reflects a broader shift in how former industrial land is being repositioned. Manufacturing heritage can provide a design language and local identity, but the harder task is creating a place that functions well over time. Waste storage, energy infrastructure, cycle provision, overheating risk, play space, accessibility, servicing, and the boundary between public and private space all have to be resolved before design intent can become durable urban fabric.
Market conditions remain difficult for large housing schemes. Construction costs are still elevated, building safety gateways can affect programme, and funders are scrutinising viability closely. Stronger schemes are those able to combine a persuasive planning case with a credible delivery route, infrastructure logic, and manageable phasing.
If approved, the next Portra Rise phase would add substantial housing volume to Harrow while continuing one of the capital’s more recognisable industrial-to-residential conversions. Its success will depend not only on the number of homes delivered, but on whether the streets, services, green space, and civic uses give the former factory site a lasting role in the borough.
