Building a case to build

Development rarely begins with a single green light. Increasingly, it happens when enough different pieces of certainty have been assembled to make moving forward a reasonable decision.

This week's stories provide an unusually clear view of that process. Across residential, regeneration, data centres and industrial property, projects are progressing because developers have secured some combination of planning, regulatory approval, finance, occupiers and delivery partners. None removes development risk altogether, but together they can create enough confidence to build.

At Walworth Corners in Elephant & Castle, almost the entire chain is visible. Fabrix and PATRIZIA have planning permission for the 283-bed student scheme, institutional equity is committed, Aviva Investors has provided a £69.5m green development loan and McLaren Construction has now been appointed under a £55m contract. Enabling works are underway.

That is what development certainty looks like in practice. It is not an abstract improvement in sentiment but a series of individual hurdles being cleared until a project becomes deliverable.

Railpen's High Wycombe X provides another version of the same story. Planning consent has been secured for the 145,000 sq ft second phase, but arguably the more important confidence comes from the occupier market. Tenants have already committed to 73,900 sq ft on 20-year leases, giving Railpen and development partner Wrenbridge sufficient confidence to bring forward the remaining units speculatively.

VIRTUS Data Centres is operating at a very different scale, but finance again provides the catalyst. Its £2.45bn funding package creates a long-term framework for expansion, including its planned 78MW Saunderton campus in Buckinghamshire and further investment in Slough.

The significance is not simply the size of the cheque. Data centre development requires enormous upfront capital alongside access to land and, critically, power. Securing finance on this scale removes one of the major uncertainties from VIRTUS's development pipeline and gives it greater capacity to turn planned expansion into physical infrastructure.

Elsewhere, certainty is being created through the planning and regulatory systems.

Arada's latest applications at Thameside West are designed to turn the ambition of a £2.5bn, 47-acre regeneration project into a deliverable first stage. Nearly 1,500 homes across six buildings would establish the first substantial phase, with the first two buildings now proposed entirely for social rent. The accompanying seven-acre park, public realm and waterfront connections begin to put the physical framework of the new neighbourhood in place as well.

At Bollo Lane in Acton, the hurdle is different again. Gateway 2 approval has been secured for the 21-storey Block AB in 22 weeks, allowing HG Construction to move forward as main contractor on the 429-bed student development.

That milestone is worth watching. Under the post-Building Safety Act regime, regulatory approval is now an integral part of the development programme for higher-risk buildings. The ability to navigate Gateway 2 efficiently therefore becomes another component of delivery certainty alongside planning, funding and procurement.

Taken together, the five stories offer a useful reminder that there is rarely one moment when a development suddenly becomes viable. Projects move forward through the gradual removal of reasons why they might not.

Planning reduces one risk. Finance removes another. A pre-let demonstrates demand. Regulatory approval allows construction to proceed. Appointing a contractor turns plans and capital into a delivery programme.

Perhaps that is also why broad measures of market confidence can sometimes tell us less than individual development decisions. Developers do not need every part of the property market to be booming. They need enough certainty around a particular project to justify committing capital to it.

This week's news suggests that, in several very different corners of the market, those cases to build are being made.

One to Watch: Gateway 2 becomes a development milestone

Bollo Lane secured Gateway 2 approval in 22 weeks, and the fact that both architect and contractor chose to announce that achievement is revealing in itself.

As more higher-risk residential projects move through the Building Safety Regulator's regime, Gateway 2 could increasingly sit alongside planning consent, financing and contractor appointment as one of the milestones the market watches when judging whether a scheme is genuinely moving towards construction.

For developers and contractors able to demonstrate an efficient route through the process, regulatory capability could also become an increasingly important part of their delivery proposition.

Risk Radar: The weakest link

More pieces needing to align before construction can make projects more secure when they finally start, but it also creates more opportunities for delay.

Finance can be secured while planning stalls. Consent can be granted before viability changes. An occupier can commit while construction costs rise. And a project that works financially can still encounter regulatory delays before it reaches site.

The development industry is getting better at assembling certainty, but many projects remain dependent on a chain of interlocking decisions. It only takes one of those links to move for the delivery equation to change.
