LDL’s Cambridge 25 site (c.103ha application site) forms the primary part of the proposed 113.3ha site allocation ‘Policy S/SHF: Land north of A1307, Bar Hill (Slate Hall Farm)’ in the draft GCLP “for a major new employment site”. The Indicative Spatial Framework identifying the extent of the Site Allocation is shown at Figure 1.
LDL welcomes and supports the site allocation and most of the draft Policy S/SHF wording, this being a continuation of the site allocation and policy from the Regulation 18 GCLP consultation (December 2025).
Greater Cambridge Evidence Supporting Policy S/SHF Allocation
Planning Practice Guidance (Paragraph: 001 Reference ID: 3-001-20190722) requires plan-making LPAs to undertake “An assessment of land availability [to identify] a future supply of land which is suitable, available and achievable for housing and economic development uses over the plan period.”
The Greater Cambridge Housing and Economic Land Availability Assessment (‘HELAA’), identifies that both the Cambridge 25 site (HELAA Site ID-40248) and the S/SHF site (HELAA Site ID- 05277) are suitable, available and achievable for economic development uses over the plan period.
Informed by the HELAA and the wider GCLP evidence base, SCDC/CCC have identified the S/SHF site as the most suitable site to meet the majority of Greater Cambridge’s strategic B2/B8 development requirements.
The Greater Cambridge Development Strategy Topic Paper (July 2026) explains (at para 5.27) that:
“For industrial and warehousing space, the EHNU 2025 identified a shortfall in space for the plan period that the draft plan needs to meet. As set out in tables 5 and 6 below, sites identified in the Proposed Submission Local Plan provide a flexible supply that more than meet the identified industrial and warehousing floorspace needs for the plan period, noting that precise delivery timing of space at the sites is uncertain. In particular, at the mixed use strategic allocations, delivery typically follows behind that of housing, and as such may come forward beyond the plan period. Land at Slate Hall Farm, Bar Hill, is a very large site that will come forward in phases and may also continue beyond the plan period.”
The Development Strategy, forming policy S/DS, identifies the S/SHF site as one of the “strategic scale allocations…proposed to meet the majority of the development needs to 2045 and beyond” as follows (at 2 e. i.):
“Slate Hall Farm, Junction 25, A14 - an allocation for master-planned employment-led development that responds sensitively to the local landscape and secures access to new green infrastructure for future workers and the local community: including approximately 220,000 square metres employment floorspace for industrial and warehousing uses, with a mix of small-medium units to support the growth of a wide range of different businesses;”
The Greater Cambridge Sustainability Appraisal (LUC, July 2026) (paras 5.714-5.722) assesses the draft allocation against the relevant 13 of the 15 Sustainability Appraisal objectives (at Table 5.71), finding the site to score positively against all criteria, bar the ‘efficient use of land’ objective.
LDL Additional Evidence Supporting Policy S/SHF Allocation
Following pre-application engagement with the GCSP, SCDC and other stakeholders, LDL submitted an Outline Planning Application (OPA) for the Cambridge 25 site (ref.26/02534), validated on 03 July 2026, for the following development:
“Development of up to 230,000 m2 GIA of employment floorspace (within Use Classes E (g)(i), E(g)(ii), E(g)(iii), B2, and B8) together with supporting community and amenity space (within Use Classes F1, F2, E(a), E(b), E(d), and E(f)), nature park and biodiversity zone, service yards and parking areas, formation of primary means of access, associated landscaping, earthworks, drainage and other associated works (outline, all matters reserved except for the principal means of vehicular access to the Site).”
The OPA scheme and the associated plans and assessments (at Appendix 1) serve to demonstrate how the Cambridge 25 site and wider site allocation and policy are proposed to be realised and add to the Councils’ GCLP evidence that this site allocation can successfully and promptly be delivered to meet a significant proportion of the identified employment land requirement. The Cambridge 25 ES and the OPA planning assessments provide detailed assessments of the suitability of major industrial and logistics development on the S/SHF site (also at Appendix 1).
The Planning Statement (Planning Prospects, June 2026) (Appendix 1) draws those Cambridge 25 assessment findings together in its conclusion (at para 8.13) that:
“The Proposed Development is supported by a comprehensive suite of technical documents. These deal with the need for the scheme, the socio-economic benefits, and then aspects of design and sustainability, landscape and visual considerations, transport and highways, noise and vibration, air quality, ecology and trees, the historic environment, ground conditions, soils and agricultural land, water resources and flood risk, and health impacts. Considering this material as a whole, the Proposed Development is shown to be acceptable, subject to mitigation measures and taking account of identified impacts. In a number of cases – for example in terms of landscape and visual considerations, transport and highways, amenity, arboriculture, and ground conditions – particular attention is drawn to the eminent suitability of the Site to accommodate development of this type.”
We have also prepared a HELAA Update for the Cambridge 25 site (HELAA Site ID-40248) (at Appendix 2) to further demonstrate that the site is suitable, available and achievable for major employment park development, drawing on the plans and assessments forming part of the OPA (ref. 26/02534/OUT) submission.
Salhia and LDL are committed to the successful implementation of its Cambridge 25 employment park development on its land and the realisation of the wider allocation site, contributing to the economic vision and growth priorities of the GCLP. Salhia’s development track record and plan for the delivery of Cambridge 25, following planning permission, are explained in its Delivery Statement (at Appendix 3).
Salhia anticipates that construction of the completed development will be phased over several years, guided by market requirements, with the indicative development timetable (ES para 3.4.1) (Appendix 1) currently anticipating that the first buildings being completed in 2029.
Proposed Substantive Modifications to Policy S/SHF
LDL supports the site allocation and most of the draft Policy S/SHF wording. However, we consider it is necessary to seek substantive or clarification modifications to a limited number of elements within the policy, to ensure the policy is more appropriately worded and more consistent with the most up to date available evidence. We also comment on and seek changes to elements of the Supporting Information (text) to the policy.
Annex 1 at the end of this letter / representation sets out our recommended (substantive and clarification) changes to Policy S/SHF: Land north of A1307, Bar Hill (Slate Hall Farm). An explanation of our recommended amendments is provided below:
Uses
The strategic location, size and context of the S/SHF site allocation make it the most suitable and sustainable site for strategic B2/B8 uses in Greater Cambridge. However, we consider it is also appropriate for this to accommodate an element of E(g)(iii) (Light Industrial) use within the site allocation, for reasons including:
1 The Council’s evidence on industrial need (in the Greater Cambridge Employment and Housing Needs Update 2024 - 2045, published in 2025 [‘EHNU 2025’]) does not differentiate between light and general industrial uses.
2 The Development Strategy policy, S/DS, in identifying the strategic scale allocations proposed to meet the majority of the employment development needs, identifies a number of sites suitable for a mix of employment uses including ‘industrial uses’ and ‘industrial processes’ – i.e. without distinguishing between light and general industry.
3 The proposed affordable workspace and creative industries policy, J/AW, treats E(g)(iii) light industry alongside B2 general industry and B8 warehousing in limb 2., separately from E(g)(i & ii) in limb 1.
4 It is important for there to be a choice of locations for all manufacturing businesses who may wish to locate or expand in the Plan area, including those of a more routine, light industrial, nature, for whom there is commercial benefit in clustering alongside a B2/B8 cluster.
Therefore, whilst there are some differences in the specific locational and market requirements of the general industrial and logistics sector from light industry, the two industrial uses should not be defined separately in a Local Plan land use context.
We also consider that, in addition to the appropriateness of identifying some Class E(g)(iii) (Light Industrial) use within the land use mix at this Employment Park site allocation, there is also masterplanning and design merit in doing so because light industrial uses generally require smaller units and so encouraging a wider range of building sizes.
However, we do consider the broadening of the acceptable land uses within this allocation to include Class E(g)(iii) light industry uses should be controlled to comprise a small proportion of the Employment Park development, to ensure that it does not prejudice meeting the primary strategic B2/B8 needs for development on this site.
On this basis, for the policy’s soundness to be more robust, and consistent with LDL’s representation on Policy S/DS: Development Strategy, we consider it is necessary to insert an additional sentence within policy S/SHF 6, as follows:
“Class E(g)(iii) (Light Industrial) uses, where the total amount and Class E(g)(iii) (Light Industrial) floorspace does not exceed 30,000 sq m gross.”
Context
Bullet 9 of policy S/SHF states that the development at Land North of A1307, Bar Hill (Slate Hall Farm) must: “Mitigate the impact of the development on Slate Hall Farm, a potential non designated heritage asset.”
Bullet 16 then states that: “Slate Hall Farm must be retained as a potential non designated heritage asset.”
This is not consistent with the 2026 HELAA for the site (HELAA Site ID: 05277) which confirms that Slate Hall Farm is not a Non- Designated Heritage Asset, stating:
“The additional information has been assessed, and it is agreed that Slate Hall Farm buildings are not considered to be non-designated heritage assets. Therefore, from a built heritage perspective, the RAG score has been updated to green”.
That additional information comprised ‘The Slate Hall Farm Building Heritage Appraisal’, undertaken by RPS Tetra Tech, 26 January 2026, (at Appendix 4) – this originally formed part of our GCLP Reg18 representation, 30 January 2026. For the reasons explained in the statement (pg.2)) it concludes that “We therefore adjudge the Slate Hall Farm building not to be a non-designated heritage asset.”
More recently, the Greater Cambridge’s Conservation Officer has confirmed in their consultation response (dated 04 August 2026) to Outline Planning Application (ref. 26/02534) (at Appendix 5), that:
“It had previously been queried whether Slate Farmhouse constituted a non-designated heritage asset (NDHA), however a heritage assessment provided as part of the Local Plan call for site HELAA showed the site had undergone lot of modern development and changes and it is agreed that the building is not considered a NDHA, so can be excluded from the impact assessment.”
Accordingly, we consider that bullets 9 and 16 should be deleted to be factually accurate and ensure this policy is justified and therefore sound in accordance with Paragraph 36 (b) of the NPPF 2024.
Proposed Clarification Modifications to Policy S/SHF
Introduction
• Bullet 1- Below amendment required to remove closed list of who can prepare the Site Wide Masterplan, as this is not justified. For example, it could also be prepared by a developer or prospective occupier(s).
“A site wide Masterplan will be prepared in conjunction with the Council and in consultation with the local community and other stakeholders. The Masterplan should be broadly aligned with the indicative Spatial Framework shown at Figure 89 and will need to identify the broad distribution of land uses, infrastructure delivery and phasing and will be used as a basis for the consideration of subsequent planning applications. The masterplan should be agreed by the Council prior to the approval of any planning applications (and may be subsequently updated by the landowners and/or promoters and agreed by the Council).”
Built Form
• Bullet 13- Below amendment required to provide a more accurate description of Figure 85- Indicative Spatial Framework for Policy S/SHF: Land north of A1307, Bar Hill (Slate Hall Farm).
“Focus built form on the north-west and central parts of the site, with the area to the south-east providing substantial green infrastructure, and water management features along the Oakington Brook.”
• Bullet 14- Below amendment required to clarify where in the site the building heights need to step down to respond to heritage sensitivity. This would also reflect the Parameter Plan and Design Code for the Outline Planning Application.
“Management of impact on landscape by ensuring heights are scaled down to the sensitive edges on the western corner of the site, the mass is organised to avoid a ‘block’ effect and sufficient screening is installed.”
• Bullet 15- Below amendment to align with NPPF para 215 on the need to balance harm to significant to a designated heritage asset against the public benefits:
“Through the preparation of a Heritage Impact Assessment, protect as far as possible, and where appropriate, enhance the significance of heritage assets and their setting, including the Grade II The Grange, Grade II* Parish Church of All Saints, Lolworth and Grade II 2 and 4 The Green.”
Movement
• Bullet 21a- Replacement of word ‘optimal’ with ‘appropriate and sustainable’, as optimal is undefined and difficult to measure.
“…the development optimal appropriate and sustainable transport outcomes, including maximising site internalisation and high active and public transport mode shares;”
• Bullet 21b- (1) Clarification that trip budget will cover the peak hours of the day for clarity. (2) Removal of requirement that a definitive trip budget needs to be agreed “prior to submission of the outline application”, as a vehicular trip budget is normally agreed during the planning application transport assessment process.
“The quantum and mix of development can be delivered within the agreed vehicular trip budget covering the peak hours of the day. A definitive trip budget based on detailed evidence must be agreed with the Local Highways Authority. A monitor and manage approach will be taken to ensure that the development remains within the agreed trip budget for the site throughout its delivery.”
Lifespan
• Bullet 26- Clarification:
“In addition to the requirements on the validation checklist, the following will be required at the submission of a major planning application:
• Bullet 26 (a, b +g)- Moved to a new bullet (27) detailing requirements for reserved matters and detailed applications:
“Reserved matters and detailed planning applications will also be required to submit:
a A comprehensive environmental management and construction strategy for all phases of development required;
b Strategies for the long-term management and maintenance of landscape, drainage and green infrastructure; and
c The approach to the long-term management, maintenance and stewardship of the site, including its infrastructure, services, facilities and built and natural environment, must be identified at the outset through a Management and Maintenance Plan that sets out a comprehensive approach to the long-term management of the site as it evolves.”
Proposed Amendments to Supporting Information
Small and Medium Scale Commercial Uses
Policy S/SHF requires “a flexible range of appropriate units that can support a wide range of businesses and that can be adapted to accommodate changing business requirements within the following uses classes”.
However, the supporting information to the policy, refers to “…small and medium scale commercial uses…” when referring to a flexible range. This conflicts with policy, is inappropriate and overly prescriptive in relation to the type and size of units, given the employment need and demand and site suitability for a range including larger units on a strategic site allocation.
The prescriptive approach contradicts both the NPPF 2024 (paragraph 87b) and the NPPF 2026 (Policy E1 2.), as well as the property market needs evidenced in the area (relating to both the Council’s evidence, namely the Greater Cambridge Warehouse and Industrial Space Needs Report (2025) and the Market Demand Assessment Chapter of the Cambridge 25 Market Assessment (Savills, May 2026) (at Appendix 6).
This report (at paragraphs 6.3.2 to 6.3.5) demonstrates that, in commercial property market terms, the size of any unit does not directly relate to the market it serves - i.e., local or regional needs. The key points are:
1 There are already a number of both local and national/international companies in Greater Cambridge that occupy industrial units above 100,000 sqft (Appendix 6, Table 6.1), for example:
a Cambridge University Press & Assessment (CUPA);
b Fred Smart Logistics; and
c Hain Daniels.
2 In addition, it is important to highlight that compared to other locations with similar economic dynamics, such as Oxford, Sheffield, Bedford, Bristol, and Norwich (Appendix 6, Section 6.4.3), Greater Cambridge is considerably under-providing larger scale industrial units. These comparable centres have a far higher representation of larger scale units over 100,000 sq. ft. This is evidential of the supply in Greater Cambridge, having been artificially suppressed relative to comparable locations elsewhere; it also highlights the vital role that such units play enabling the proper function of the I&L market.
3 The last eight years of policy restriction, since the adoption of South Cambridgeshire LP Policy E/11, has severely constrained existing businesses from finding suitable accommodation within Greater Cambridge due to a lack of availability of premises of sufficient scale. Examples include Marshalls, Cambridge Aerospace and DHL (Appendix 6, paragraphs 6.4.6- 6.4.12).
Extrapolating these trends, the latent demand for larger-scale units will continue increasing, and the lack of such provision will displace investment further away and jeopardise the retention of existing businesses, if they are unable to accommodate their growth plans within Greater Cambridge.
Furthermore, the Council’s evidence, namely the GCW&ISN 2025, cites the ‘Understanding demand for B8 premises across Greater Cambridge’, authored by WSP in 2021 on behalf of Greater Cambridge Partnership and the Greater Cambridge Shared Planning Service, which presents the findings of the engagement with the industry (19 interviews with stakeholders), and indicates that there is latent demand for larger scale units in the area with emphasis on the need for medium- to large-scale B8 units.
We would finally draw attention to the West Suffolk Local Plan Examination in Public and Inspector’s Report (July 2025) (Appendix 7), where a similar size unit cap for logistics units was removed (see para 250, repeated below):
We concluded under main issue 1 that there is significant demand for large scale strategic logistics development in the wider sub region, and an identified need for 35 hectares in West Suffolk. The restriction on such developments comprising more than 9,000 sqm is not therefore justified or consistent with national policy which recognises the critical role that such development plays in enabling an efficient, sustainable and effective supply of goods for consumers and businesses as well as contributing to local employment opportunities. Policy SP12 therefore needs to be modified to allow large scale logistics development on suitable allocations and employment areas, provided that it is consistent with national policy and does not prevent more localised needs being met. (Lichfields emphasis).
In comparison, the GCSP evidence in the Iceni report (2025 GC Employment and Housing Needs Update) identifies a minimum need in Greater Cambridge for 317,000 sq m of new B2/B8 Employment floorspace to 2045, with an existing critical undersupply of land and premises to meet the needs of the I&L sector and this is particularly severe in relation to large units (Appendix 6, para 5.5.4).
On the above basis, and consistent with LDL’s representation on Policy S/DS: Development strategy, we would also seek an amendment to the supporting text to ensure this accords with para 36(d) of the NPPF 2024, as follows:
“The policy enables a range of commercial uses to come forward and it will be important that there is sufficient variety in their form and floorplate size and flexibility in their design to ensure that they cater for a range of different business types and can be adapted over time to meet changing local business needs. As the focus of the site should be on meeting the identified local Greater Cambridge needs, the site should deliver a range of appropriate unit sizes. Development should come forward in phases.”
