The Decisions That Matter Most Before Planning

By the time a scheme reaches committee, many of the most influential decisions have already been settled. Development consultants working at this stage rarely make fundamental changes to a scheme, but those involved earlier can shape outcomes while options remain open.

The real cost drivers of a site are often set early, before they appear on drawings. Access, topography, services, heritage and context can dictate viability if they are treated as assumptions rather than variables. By the time a scheme takes shape, these constraints are no longer flexible, and their cost implications are locked in, whether or not they were fully understood at the outset.

Planning consent can often be mistaken for proof of deliverability. Yet schemes can fully comply with policy and still prove difficult to deliver in practice. Planning parameters such as massing, façade design or sequencing can fundamentally influence how a project is built, how it is procured and how long it takes. If these factors are not challenged early, projects can succeed on paper yet fail in delivery.

Funding appetite is often shaped well before planning consent is secured. Lenders and investors form early views based on perceived risk, viability and clarity of strategy, not planning consent. Initial assumptions around cost, programme and exit value influence capital availability, pricing and tolerance for change. Once these positions harden, revisiting the fundamentals once established can be difficult.

Taken together, these factors explain why early decisions carry disproportionate weight. Before planning fixes key parameters, opportunity remains to test options, challenge assumptions and align design ambition with commercial reality. As momentum builds, that flexibility diminishes, and the early decisions begin to define outcomes long after they can sensibly be changed.
