Greenfield and Brownfield Sites

What are these differing types of land for development, and how does it impact site viability?

 

Brownfield Sites (aka Previously Developed Land)

Previously developed land or ‘brownfield sites’ comprise any land currently or previously occupied by a permanent structure, including surrounding land and any associated fixed surface infrastructure; Government policy encourages re-use of this land type.

This category of land typically has a high existing use value (EUV). National planning guidance accepts that land will not come forward for development unless the land owner receives the EUV plus a premium. Find outmore about use values.

Previously Developed Land services will accurately identify the best possible EUV and premium which, together with viability reporting, will establish the true uplift in value generated by the grant of planning consent and thereby establish funds available to pay for contributions to Affordable Housing and other Infrastructure Contributions.

This process ensures that contributions are paid from the uplift in value generated by the planning consent (as they should be), not from developer profit or existing land values.

 

Greenfield Sites (aka Undeveloped land)

Greenfield land is broadly agricultural and garden land, and should not be confused with Greenbelt land, which is largely protected from development. The term Greenfield is used largely to denote areas which have not been built on – ie, the fields are still green. The term is used in a wide range of industries, but when it comes to development:

Typically, uplifts in value on the grant of planning permission are substantial and therefore a level of on-site affordable housing is to be expected.

Local Plan Viability Studies generally accept that a substantial uplift above agricultural values should accrue to the landowner in order to provide an incentive to bring the land forward for development.

Greenfield Sites present different challenges to Brownfield development; there will be substantial infrastructure costs, environmental and conservation issues to consider. These are commonly under-estimated by LPAs. Early stage modelling can establish the density of development required to satisfy policy requirements, and thereby better inform LPA choices.

Greenfield Site viability services will ensure the proper inclusion of infrastructure and construction costs to document the true uplift in value generated by the grant of planning consent, and thereby establish the fund available to contribute to Affordable Housing and Infrastructure Contributions.

Proposals to 'scrap s106 developer contributions' and new flat-rate ‘Consolidated Infrastructure Levy’

S106M comment on reports suggesting the government's proposals to scrap section 106 developer contributions, affordable housing policies and CIL and replace them with a 'Consolidated Infrastructure Levy' will be included the Queen's Speech and come forward for consultation shortly. We outline the potential challenges and propose a constructive solution.
Appeal win: Strategic 86 unit housing site appeal allowed with zero s106 contributions

Appeal win: Strategic 86 unit housing site appeal allowed with zero s106 contributions

Appeal win reducing 17 affordable houses to zero on the basis of high infrastructure costs. S106M provided viability reporting, extensive negotiations with the council and appeal statement of case and further affordable housing statements to support this recent Appeal in North East Lincolnshire for 68 houses and 18 apartments on part of a large strategic site adopted in the local plan and previously consented.
