South Cambridgeshire Planning Consultant
Green Belt villages and new towns
South Cambridgeshire wraps around the city and holds most of the area's growth, from Northstowe and Waterbeach to Cambourne and Bourn Airfield. Around a quarter of the district is Cambridge Green Belt, and the rest is a patchwork of 85 conservation areas, village development frameworks and open farmland. Cedar Planning helps owners, builders and landowners find a policy route through it.
We are Chartered Town Planners and prepare applications under the South Cambridgeshire Local Plan 2018, with an eye on the emerging joint plan.

Planning in a district shaped by growth and Green Belt
The 2018 plan sorts villages into a hierarchy. Policy S/8 names the Rural Centres of Cambourne, Cottenham, Great Shelford and Stapleford, Histon and Impington, and Sawston, followed by Minor Rural Centres under S/9, Group Villages under S/10 and Infill Villages under S/11. The category decides how much housing a site can take. Outside the development frameworks defined under Policy S/7, new homes are generally resisted.
The Green Belt covers much of the land between the city and the necklace of inner villages. Policy S/4 protects it, Policy NH/8 addresses development in and next to it, and Policy NH/9 deals with infilling and previously developed sites. National grey belt changes add another angle for some brownfield and edge-of-village land.
Large new communities dominate the housing figures. The proposed submission version of the joint plan counts on Northstowe for 6,382 homes, Waterbeach New Town for 5,721 and Cambourne North for 2,550, alongside Bourn Airfield. For smaller applicants, that growth matters mainly through infrastructure demands and design expectations.
The councils reported a combined five-year housing land supply of 5.6 years in March 2026, so speculative village schemes cannot rely on the tilted balance and need a clear policy basis.
Check the framework line first
Whether a plot sits inside or outside a village development framework is often the single most important fact in South Cambridgeshire. We confirm it on the policies map before any design work, because it changes which policies apply.
South Cambridgeshire-specific planning issues
Villages such as Great Shelford, Histon and Coton are ringed by Green Belt, so beyond their frameworks extensions, outbuildings and replacement homes are tested for proportionality and openness.
Policies H/13 and H/14 govern extensions and replacement dwellings in the countryside, and H/17 the reuse of rural buildings for housing. Each has its own tests on scale and character.
Chalk aquifers are over-abstracted, a Grafham to Cambridge transfer is expected around 2030 to 2032, and the Fens Reservoir later. Water efficiency under Policy CC/4 is closely checked.
With 85 conservation areas and only 22 appraisals, officers often assess character case by case. A clear heritage statement fills that gap for Policy NH/14.

The South Cambridgeshire Local Plan 2018 remains the adopted plan, alongside made neighbourhood plans in a number of parishes. Applications are handled by Greater Cambridge Shared Planning, but policies are specific to the district: the S policies on strategy, the HQ policy on design, the NH policies on environment and heritage, and the H policies on housing.
The joint Greater Cambridge Local Plan covers 2024 to 2045 and proposes 48,069 homes and 73,300 jobs, most already in the pipeline. Its final consultation ran from 3 August to 25 September 2026, and submission is planned by December 2026. Water is a recurring theme; the plan makes Cambourne North subject to the necessary water infrastructure being available.
Delivery bodies are changing too. Government laid an order in June 2026 to establish a Greater Cambridge Development Corporation, with separate plan-making and development management powers expected later in 2026. We keep track of how that will affect decision-making on the largest sites.
Key policy areas we navigate
Policy S/7 decides whether a site is within a village or treated as countryside.
Policy H/16 sets tests for new homes in gardens, including character, amenity and access.
Policies S/4, NH/8 and NH/9 control openness, infill and redevelopment of previously developed land.
Policies E/16 and E/17 support business expansion and conversion of rural buildings for employment.
A Consultancy That Works With You, For You
In South Cambridgeshire the same proposal can be acceptable on one side of a village and refused on the other, depending on the framework line, the Green Belt boundary and conservation area status. Early professional advice avoids designing a scheme around the wrong policy.
We work across East Anglia, including Cambridgeshire, and deal with Greater Cambridge Shared Planning regularly. Site visits are arranged as each project needs.

South Cambridgeshire Planning FAQs
How do I know which village category my site falls in?
The 2018 plan lists every settlement under Policies S/8 to S/11. Rural Centres such as Sawston and Cottenham can take larger schemes; Infill Villages allow only very small ones. The category, plus the development framework boundary, sets the starting point for any housing proposal.
Can I build a replacement house in the Green Belt near Cambridge?
Possibly. A replacement building in the same use that is not materially larger than the one it replaces can be appropriate development. Policy H/14 adds local tests. We compare volumes and footprints before you commit to a design.
Does Cedar work on sites at Northstowe or Waterbeach?
Our focus is usually smaller schemes, but we advise on reserved matters, variations and householder changes within the new communities, and on land promotion nearby through the strategic land service.
Will water supply limits stop my application?
For most householder and small housing schemes, water supply is addressed through efficiency standards rather than as a reason for refusal. Larger allocations may be phased to water infrastructure. We check current advice from the Environment Agency and the councils at the outset.
Is Class Q or a full application better for a barn near Linton?
It depends on the building's structure, location and planning history. Class Q gives certainty on principle but limits works. A full application under Policy H/17 allows more design freedom but must meet local tests. A feasibility study compares both routes.
