It states that the viewpoints are intended to be only a sample, to which other identified views, both from the green countryside surroundings and from within the city, may be added. The findings of the study, including the methods used and advised, have underpinned local plan policies since their completion. They are an important tool in informing and understanding the impact of new developments on the skyline. The most recent version of the tall buildings policy is more versatile, opening up the possibil- ity of new positive contributions to the skyline. This has been a controversial change, and the question as to whether new elements might be appropriately added to what is an iconic profile is complicated. However, the original group, identified in the verses of Matthew Arnold or the illustrations of JMWTurner, is not of a single form, profile, age or indeed architectural style, but rather a group of very different spires, domes and towers constructed at different periods in history, from St George’s Tower (1071) to the copper-clad ziggurat of the Saïd Business School (2001). Nothing unifies them apart from the fact that they rise above the ‘grey beauty’ or ‘base and brickish skirt’ in views from the surround- ing countryside where people walk and have observed the city over centuries. Oxford is a relatively small city, hemmed in by its rivers, the Thames and Cherwell, and surrounded by green hills. From many places within the city it is possible to glimpse the surrounding countryside: this is one of its absolute delights. Expanding from its walled medieval core, the city has absorbed a number of the surrounding stone-clad settlements, such as Headington, Marston and Wolvercote. By virtue of an acknowledged balance between local resident and authority controls, these set- tlements have managed to preserve their sense of place. In some cases the open spaces in between have survived as riparian meadows along the Cherwell or Thames, such as the historic com- mons of Port Meadow, a large area of grassland to the north-west of the city that has been used for grazing since the bronze age, or South Park, an open green space given to the people of Oxford by the Oxford Preservation Trust in 1951. These vital spaces give generously those moments at dawn and dusk when the spires and towers of the city emerge from the gentle mist, or glow in the receding evening light with all the accompanying sounds. The boundaries of the city are tight. Much of its surrounding countryside, including city suburbs, are controlled by others to whom the city must trust their protection against the tide of houses destined to become the homes of fami- lies working in the city. Space for development, particularly housing, within the city’s boundary is at a premium. Pressures come from the uni- versities for student and staff accommodation and from the ever-increasing number of spin-off or research-and-development companies. Looking at the present character of the city’s residential suburbs, relatively low-rise housing, and sensing the pressures on the individual col- leges and universities to improve their facilities, the city’s planners began to consider tall build- ings. Would it be possible to make good places for people with beautiful spaces around them without harming the skyline? The topography meant that building not very high in certain places would be substantially harmful to other places. It might, however, be possible to increase densities, building up with medium-density housing surrounded by exciting outdoor spaces, and not impact on the important views of the ‘dreaming spires’ or out from the city to its amphitheatre of surrounding hills. Working with a local landscape architecture practice and engaging local stakeholders, the city council developed a policy supported by a technical advice note (TAN) for high buildings. Neither theTAN nor the policies that it supports seek to be prescriptive. The purpose is to estab- lish a method that can be applied to each case to establish the impact that a design would have on important and protected views. The document is intended as a tool for positive, iterative design, based on an understanding of the impact of a design with regard to a building’s height, mass and appearance. The TAN carefully avoids defining ‘high’, explaining that it will be entirely dependent on context. The document shows how layers of information can be built up to inform decisions as to where it may be possible to increase build- ing heights in parts of the city without impacting on the characteristics that it is important to preserve. The evidenced-based report that sits behind the TAN builds on the work of earlier studies, including theView Cones Study of 2015, and takes into account other policies within the local plan, including the Carfax policy. The report also identified important views out of and within the city, exploring methods of analysing the impact of taller buildings. The TAN sets out those methods with worked examples and begins to identify areas of the city that might be suitable for taller buildings. Encouragement is given to developers to engage with the process at the earliest stage of design development. A number of projects that have been through this process are under construction. It will be interesting to see how comfortably they sit in their context. Gill Butter is an architect and a principal heritage officer at Oxford City Council.
