Planning for sustainable historic places

In the heritage sector, sustainable development should be discussed not only in terms of efficient building performance, but also in the wider context of place and planning.

Those who plan for historic places need to assess the sustainability values of the area (social, economic, environmental) in addition to understanding heritage values.

Such analysis needs to address uses, live / work patterns, movement, and other factors, such as:

  • Mixed use. Historic areas have developed incrementally over time and usually have a finer grain of mixed use, reducing the need for car-based journeys. Sometimes there are residential uses located above commercial uses. There is a greater tendency to single use where places have been comprehensively redeveloped.
  • Choice and diversity. Research has shown that historic areas support more independent businesses. Minority or low-profit goods are usually to be found in older more peripheral areas, where rentals are lower, rather than in newer shopping areas.

Urban design analysis often shows that historic areas have superior characteristics in terms of layouts, mixed use, concentrations of facilities, permeability and other characteristics. Good planning can build on these qualities.

It is also important to recognise the different ways in which historic buildings and areas support sustainable and inclusive economic growth, and fulfill community needs. This is often through the natural process of growth and decline, and resulting changing property values.

Most city and town centres have transitional areas, where traditional industries or commerce have declined, leading to suppressed property values. In such areas, historic buildings are often the means to providing flexible and affordable accommodation, essential to supporting enterprise, creative businesses, knowledge-based business, social enterprises, specialist goods suppliers and minority goods. So heritage can help to deliver not just more sustainable, but also more inclusive growth.

New development in historic areas can make places more sustainable or, if poorly conceived and designed, less. Groups involved in preparing neighbourhood plans often address heritage issues, either through specific heritage policies or through land use, growth, urban design and other policies that impact on how historic buildings are used, and on how historic areas adapt to meet the needs of current and future generations.

In relation to planning policies, the National Planning Policy Framework (NPPF) defines sustainable development as having social, economic and environmental dimensions. So heritage is considered by neighbourhood planning bodies as an integral part of the wider social, economic, and environmental planning of the area.

The basic conditions that neighbourhood plans must meet include achieving sustainable development. Achieving sustainable development could address various issues:

At a more strategic level, the serious discrepancies in economic performance between different parts of the country represents a serious threat to sustainable growth. Land and house-price inflation are severe problems in some parts of the country, especially London and the south east.

At the same time, there are many parts of the country where the development sector has yet to recover from the economic problems of almost a decade ago. In other areas, there is an imbalance between costs of housing and the strength of the local economy, fuelled by a range of factors such as second-home ownership and commuters (in Cornwall and rural Norfolk, for example). In many rural areas, high house prices exclude many working in the rural economy.

Less than a decade ago, the housing pathfinders were based on a broad-brush view that there was an over-supply of housing in those areas and a need for managed decline. This led to the destruction of many houses, without proper consideration of alternative strategies involving retention and creation of demand. It is now difficult to reconcile this with the current emphasis on the national housing crisis. It is interesting to note that heritage bodies like SAVE rigorously campaigned against the pathfinders at the time.

The aftermath of this policy is still to be seen in areas such as Liverpool and Stoke-on-Trent. In fact, the issue for such housing is one of under-demand and economic viability. The challenge is in how to incentivise employment-creating development in these areas, so as to create demand for residential properties, making their refurbishment more viable. The problem is one of geographical economic imbalance.

Managed decline is a negative and unsustainable concept. It is planning for failure. Just a few decades ago the waterfront and city centre in Liverpool were the subjects of a debate about managed decline. Thankfully those arguing for managed decline lost and the Albert Dock was listed. Today Liverpool is a vibrant city centre and the waterfront was recently voted in an RTPI poll as the greatest place in England.

The challenge for the heritage sector is in reconciling heritage conservation with the need to create fit-for-purpose, sustainable and inclusive places. For professional heritage practitioners involved in managing or supporting change, a complex range of factors is involved, including land use, transport, movement, permeability, townscape, economic development, town centre viability and numerous other factors.

So building performance is part of a much bigger picture for heritage and sustainability, with social, economic and environmental dimensions. Indeed, it is not sustainable practice to improve the performance of a building, if it then accommodates a new use in an unsustainable location.

There is an apparent mismatch between the sometimes narrow ‘buildings’ focus on sustainability and the way it is being addressed by those who live, work and own property in historic buildings and areas. This is especially the case for those who are now involved in planning for the future development of their areas through neighbourhood plans or community-led development, the latter sometimes including taking on heritage assets.

While not diminishing the importance of retrofitting, there is a problem if this is the sole focus, excluding consideration of what makes places sustainable. The challenge for national heritage bodies is on how best to support people and groups actively involved in conservation in different localities. To achieve this, a comprehensive and all-encompassing perspective is required. To focus on building performance in isolation rather misses the point
