Grand Union Phase 4C in Brent has secured reserved-matters approval for 505 homes across three towers, with the council’s official planning register recording a grant of permission on 17th September 2026. The decision concerns detailed design for part of Berkeley’s wider canal-side regeneration, not a wholly new outline permission for the entire neighbourhood.
The buildings, designed by Sheppard Robson, are planned for Plot L of the former Northfields Industrial Estate in Alperton. Industry reports published on 9th October say the tallest tower will rise to 29 storeys and that the phase is intended to complete a north-south green route linking Beresford Avenue with the site’s central linear park.
The official record identifies application 26/0840 as decided by a delegated team manager, with permission issued on 17th September. That matters because contemporary coverage describes a new approval, but it is not evidence of a 9th October committee vote. The reserved-matters decision follows earlier hybrid and Section 73 permissions and does not remove other pre-construction requirements.

Grand Union Phase 4C: what Brent has actually approved
The Brent Council application summary confirms reference 26/0840, received on 31st March and validated on 28th April 2026. It describes a reserved-matters application pursuant to condition 3 of hybrid consent 25/2943 for the layout, scale, appearance, access and landscaping of Phase 4C.
The council lists the application status as ‘Decided’, its decision as ‘Permission Granted’ and the decision issued date as Thursday 17th September 2026. The decision is attributed to a delegated team manager in the published planning record. There is no basis here for attributing the approval to a later committee debate or vote.
The approved matters include the residential buildings, basement parking, cycle parking, amenity areas, landscaping and associated public-realm works. They establish detail against the underlying planning framework; they do not mean every remaining condition or technical agreement relating to construction has already been discharged.
The official document register contains a final delegated report and decision notice both dated 17th September, together with the accompanying plans and technical reports. Those records should take precedence over descriptions in secondary press coverage when confirming the date and legal nature of the decision.
505 homes, three buildings and a taller skyline
The approved phase comprises 505 dwellings, described in Building Design’s 9th October coverage as private homes. It is one of several residential phases within the wider Grand Union masterplan, rather than a standalone scheme divorced from its shared infrastructure.
The three buildings are identified in the applicant’s material as L1, L2 and L3. Drawings in Brent’s planning register show different footprints, storey heights and orientations, with the tallest reaching 29 storeys according to the architect’s contemporary project description.
Sheppard Robson has described a palette including light-coloured brick, pale green precast concrete and metal balconies, with industrial references intended to acknowledge the history of the Northfields estate. A curved pavilion is planned to engage with the adjacent public space.
These architectural details are relevant to the reserved-matters decision because appearance and scale were specifically among the matters submitted for approval. However, an attractive published visualisation is not a substitute for examining the actual approved elevations, materials conditions and associated landscape plans.
Why reserved matters are different from full permission
The broader site is already governed by a sequence of planning decisions. Brent’s planning file cites an earlier hybrid permission, 20/2784, for phases of the comprehensive mixed-use redevelopment. A subsequent Section 73 application, 25/2943, varied specified energy-related conditions of that permission.
Phase 4C application 26/0840 is a reserved-matters submission under the resulting hybrid framework. The principle and broad parameters of development were established through earlier permissions. This September decision addresses the matters left to be settled for Plot L rather than reopening every land-use and capacity issue across the whole estate.
This distinction is more than terminology. Applicants relying on an outline permission must ensure reserved details remain within its parameters, meet the relevant conditions and are supported by information adequate to assess effects. Detailed approval cannot be treated as permission for departures from the parent consent.
The application description also refers to information for four conditions: sound attenuation, air quality and air quality neutrality, a delivery and servicing plan, and wind mitigation. Those submissions should be read alongside the specific wording of the issued decision rather than assumed to have cleared every environmental and construction obligation.
The 3,350-home Grand Union regeneration
The wider Grand Union project aims to transform former industrial land beside the Grand Union Canal and River Brent into a mixed-use neighbourhood of around 3,350 homes, alongside employment, shopping, leisure, community space and a network of public routes.
Berkeley has already delivered parts of the scheme, with contemporary reporting putting completed homes at around 1,000. The wider programme is intended to reconnect the former estate with its surrounding neighbourhood and with routes towards Stonebridge Park transport interchange.
The developer’s February 2026 statement records an agreement with Sovereign Network Group for 269 socially rented homes at Grand Union, within a wider 555-home deal across two London developments. That transaction concerns other parts of the programme and should not be presented as affordable dwellings included in Phase 4C’s 505 private homes.
The preceding Phase 4B reserved-matters application, 25/3114, was approved earlier in 2026 and covers a neighbouring plot. Taken together, the phases demonstrate why tenure totals must be reported at the appropriate plot and masterplan level rather than merged into a single headline without explanation.
Public spaces and access between the buildings
One of the practical features highlighted in the latest plans is a north-south pedestrian connection from Beresford Avenue towards the linear park. The proposed buildings are intended to provide an active edge to the central green space rather than an isolated cluster of towers.
The full design depends on the relationship among residential entrances, accessible routes, planting, play areas and active frontages. In a phased regeneration, the immediate test is not just whether a final masterplan looks coherent but whether each delivered phase is safe and usable while neighbouring plots remain under construction.
Landscape plans in the official documents should be checked for planting sizes, long-term maintenance, tree-pit design, access for residents and provision of shared outdoor space. Canal-adjacent developments also need careful attention to public movement, water-side safety and the interaction between open space and private amenity.
For residents, the key questions concern the quality of these connections and whether public spaces are genuinely accessible when individual buildings are occupied. The grant of reserved matters establishes the design detail submitted; it is not a guarantee of a precise completion date for every public-realm component.
Transport, wind, air quality and other conditions
The height of the towers makes wind microclimate particularly important for entrances, seating, walking routes and landscaped areas. Brent’s published file includes wind assessments and identifies wind mitigation as one of the condition-related matters submitted alongside the reserved-matters application.
The supporting material also includes a transport statement, delivery and servicing plan, air-quality assessment, energy information, acoustic assessment and other technical work. The presence of reports demonstrates what the applicant submitted, not that each assumption or mitigation measure has been independently verified in this news article.
Construction logistics and highway management will still matter where the development sits alongside continuing occupation and other building phases. Heavy vehicle routing, working hours, temporary diversions and safe pedestrian access may have to be controlled through separate condition approvals and construction management arrangements.
Similarly, the planning approval cannot be equated with Building Safety Regulator approval for any higher-risk buildings. Different legal regimes address planning acceptability and building safety, and consent under one does not dispense with the other.
What the decision shows about major housing delivery
The Grand Union approval is a practical example of a phase progressing through a layered permission structure. A large masterplan may have an outline element, successive variations and individual reserved-matters applications, followed by further condition submissions before work can begin.
Reporting these stages accurately matters for landowners, buyers, neighbours and planners. A planning press release can correctly say that another phase has approval while still leaving material technical, commercial and delivery steps outstanding.
The date matters too. Brent issued the formal reserved-matters grant on 17th September 2026; architecture and development publications reported it afresh on 9th October. It would be misleading to imply that a council committee voted to approve 505 homes on the latter date.
Planning Geek’s wider coverage of a 4,000-home application at Gartree Road illustrates a different stage: validation of an outline bid. The comparison is useful precisely because a validated application is not a determination, whereas Grand Union Plot L now has a recorded reserved-matters decision.
Primary evidence and next steps
Brent Council’s planning register for 26/0840 confirms the grant, decision date and description. Its documents page provides the delegated report, 17th September decision notice and approved material.
The original transport statement and planning statement explain the phase’s relationship to the earlier hybrid consent. Building Design’s report provides the architect’s account of the design and its intended character.
No fresh Section 106 signing date, commencement notice or fixed completion programme is established by these sources. The next milestones to watch are the relevant discharge of outstanding conditions, any required building-safety approvals and visible construction progress on the Phase 4C plot.
