London's Building Boom: What the Capital's Biggest New Schemes Mean for Your Neighbourhood

Three major development schemes totalling more than 4,800 homes received green lights from London councils during June, making it the busiest month for planning approvals in the capital since the second quarter of 2023. The decisions, spread across east, north and south London, signal that housebuilding — stalled for much of the past two years by rising construction costs and planning gridlock — is picking up speed ahead of the Mayor's 2030 housing delivery targets.

The timing matters. London's average house price has held above £500,000 for fourteen consecutive months, and the shortage of new supply in Zones 2 through 4 has pushed buyers further out along the Elizabeth Line corridor, where properties in Ilford and Harold Wood have seen values climb 11 percent year-on-year. Developers and housing associations are betting that approvals secured now can be translated into completions before the next election cycle reshuffles the planning rulebook again.

The Schemes Making Headlines

The largest of the three is the revised Silvertown Quays masterplan in the London Borough of Newham, which cleared its final hurdle at the end of June after nearly a decade of revisions. The scheme, managed by a joint venture between Lendlease and the Greater London Authority, now proposes 3,200 homes on the north bank of the Royal Docks, alongside 180,000 square feet of commercial space and a new primary school. Roughly 35 percent of the units will be classed as affordable, though campaigners from the Newham Renters Union had argued the figure should be closer to 50 percent to reflect local need. Construction of the first phase, focused on the stretch between Pontoon Dock DLR station and the ExCeL centre, is scheduled to begin in spring 2027.

Further north, Barnet Council gave the go-ahead in late June to the next phase of Brent Cross Town, the 180-acre regeneration scheme being delivered by Related Argent and Barnet Council itself as joint developer. This phase adds 1,100 homes around the new Brent Cross West railway station, which opened on the Thameslink network in 2023. The area has attracted significant retail and workspace pre-lets, and estate agents along the Edgware Road corridor report that two-bedroom flats in completed Brent Cross blocks are already trading at around £525,000 — a 14 percent premium over comparable stock in nearby Hendon.

The third approval — smaller but closely watched — covers a 540-unit mixed-use block on the Old Kent Road in Southwark, part of the borough's long-running Opportunity Area plan. The developer, Peabody Housing Association, intends to start on site by the end of 2026, with the first residents moving in during 2029. The Old Kent Road zone, earmarked for a future Bakerloo Line extension that remains unfunded, has seen values lag Zone 2 norms, but Peabody's scheme is already generating interest from first-time buyers priced out of Peckham and Camberwell.

What This Means for Buyers and Renters

The pipeline matters most for people currently renting in east and south London, where average private rents hit £2,150 per month in the first quarter of 2026, according to the Greater London Authority's own monitoring data. New supply at Silvertown and Old Kent Road alone will not move that needle quickly — analysts at Savills estimated last year that London needs 52,000 new homes annually just to keep pace with household formation, and the capital has not hit that number since 2017.

For buyers, the practical advice is straightforward: schemes approved now typically convert to Shared Ownership or Help to Buy-replacement products — the current vehicle is the First Homes programme — within eighteen months of groundbreaking. Registering interest directly with Peabody, Lendlease or Related Argent puts prospective purchasers on early-access lists before units reach the open market. Mortgage brokers on Canary Wharf's South Colonnade report that lenders are again offering 95 percent loan-to-value products on new-build flats under £450,000, reversing a restriction that had been in place since late 2024.

Construction starts in 2026 mean completions in 2028 and 2029. That is the window Londoners priced out of the current market are watching.
