Policy GP/ST: Skyline and tall buildings
1. Development proposals that break or result in a significant change to the existing skyline, or are significantly taller than the surrounding built form (as defined by the local context heights in Appendix H: Skyline and Tall Buildings Guidance), must demonstrate how they will maintain or enhance the distinctive skyline and character of Cambridge and the surrounding district. Such proposals will only be supported where they demonstrate a positive response to their wider setting and satisfy the following criteria:
a. Location, setting and context – applicants must demonstrate through visual appraisals, with supporting accurate visual representations, how the proposals fit within the existing landscape and townscape and demonstrate how the proposal maintains or enhances the character and quality of the skyline. Proposals for tall buildings will be assessed on a site-by-site basis with the expectation that a robust evidence base will be provided to demonstrate that they are appropriate to their context;
b. Impact on the historic environment – applicants must demonstrate and quantify the potential harm of proposals to the significance of heritage assets or other sensitive receptors (view of, backdrop and setting), assessed on a site-by-site basis. These will include impact on key landmarks and viewpoints (identified in Appendix H) and from main streets, local vantage points (such as bridges) and open spaces as well as, dynamic views from roads and, where applicable, The River Cam corridor. For Cambridge, proposals must ensure that the character and appearance of a city of spires and towers emerging above the established tree line, remains dominant from relevant viewpoints, including the Cambridge Commons;
c. Scale and massing – applicants must demonstrate using scaled drawings, sections, accurate visual representations and models, how their proposals would form a high-quality addition to the skyline. This will include assessment of the cumulative impact at both strategic and local levels with other existing or emerging proposals as well as against the baseline at the time the application is being made;
d. Design quality – applicants must demonstrate how their proposals create high quality, well-proportioned buildings expressing elegance, proportionality and verticality that articulate base, middle and top using high quality materials and detailing that architecturally integrates plant, lift overruns and flues to ensure a well-articulated skyline. Where appropriate, proposals should introduce a mix of uses that generate activity and a human scale at street level;
e. Amenity and microclimate – applicants must demonstrate that there is no adverse impact on neighbouring buildings and open spaces in terms of the diversion of wind, overlooking, overshadowing, overheating, glare and reflectivity. Proposals must demonstrate through appropriate technical testing that acceptable microclimatic conditions will be achieved and that opportunities have been taken to minimise urban heat island effects, including through design responses to wind, thermal comfort and surface overheating, and that there is adequate daylight to habitable rooms and sunlight to external spaces both within the proposals and to neighbouring properties and open spaces; and
f. Suicide prevention – applicants must demonstrate how their proposal incorporates proportionate design measures to reduce access to means of suicide having regard to the height, form and public accessibility of the building. Design will be determined by the structure of the building and its surroundings.

7.29. Cambridge will seek to maintain and enhance the overall character and qualities of its skyline as the city and surrounding district continue to grow. The city and its surroundings are largely free from clusters of modern high-rise buildings, but pressures to intensify sites often result in increased bulk and massing which needs to be carefully assessed to understand cumulative impacts on the skyline. Proposals for tall buildings within South Cambridgeshire will need to demonstrate how they can successfully fit into the overall rural character of the district. Further advice on skyline and tall buildings, along with the requirements of the assessment criteria for proposals is set out in Appendix H.
7.30. The skyline of Cambridge is characterised by a cityscape of spires and towers rising above a well-established tree canopy. Subtle variations in topography contribute to a skyline defined by a series of ‘incidents’, where prominent buildings punctuate an otherwise consistent lower-scale built form. Within the historic core, larger ‘set piece’ college buildings provide a striking contrast to more modest ‘background buildings’, which typically range from three to five storeys. In the suburbs, building heights are generally lower, although they tend to increase along key approach routes and at major junctions. The Cambridge Commons introduces a rural character that extends into the heart of the city and provides key opportunities to experience the historic environment, including scale of buildings, from these locations. Notable exceptions to the prevailing scale and massing occur at the city’s fringes, including the hospital complex at Addenbrooke’s, the hangars at Cambridge Airport, and the Research Parks situated both at the edge of the city and within South Cambridgeshire. These areas accommodate larger-footprint buildings designed to meet contemporary research and clinical needs.
7.31. Development in South Cambridgeshire is typically lower in density and domestic in scale, reflecting the rural and semi-rural character of large parts of the district, with church towers and spires rising above mature tree canopies to create visual connections between settlements. Larger-footprint research and development facilities, along with smaller-scale industrial buildings, often present a contrasting character to their surroundings. The emerging new towns at Northstowe and Waterbeach introduce the potential for buildings of greater height and massing than those found in existing villages.
7.32. Given the large number of designated heritage assets within the historic core of Cambridge, including a significant number of highly graded heritage assets of great national importance, the potential impact that a proposal for a tall building may have on the significance of those assets will be a critical factor in the consideration of the proposal. For this reason, it is very unlikely that there would be many instances or scope for introducing new tall buildings in or around the historic core. The impact on the setting of heritage assets should be assessed in accordance with the guidance set out in The Setting of Heritage Assets: Historic Environment Good Practice Advice in Planning Note 3 (Second Edition) and Tall Buildings: Historic England Advice Note 4 or any successor documents.
7.33. Developers bringing forward proposals for tall buildings should refer to Appendix H of the plan which sets out the required approach, methodology, and assessment criteria for considering skyline and tall buildings within Greater Cambridge.
7.34. When submitting planning proposals for tall buildings, developers should refer to part 3 of the Preventing suicides in public places – A practice resource published by Public Health England which sets out interventions to prevent suicide. It sets out actions that developers can implement to restrict access to the means of suicide such as implementing interventions through measures such as fencing with a minimum height of 2.5 metres in tall buildings, inwardly curving fences to make it difficult to climb out. Design of intervention(s) in tall buildings will be determined by the nature of the structure and its surroundings.
