Over the last decade or so, there has been an astonishing turnaround in the centres of our major cities, and an upsurge in the number of people living in apartments at relatively high densities.
Many have won design awards, and are attracting a new class of people to live close to their work, often in flats rented from investors.
However, once a broader perspective is taken, a very different picture emerges.
Achieving an urban renaissance means stemming the urban exodus, and tackling polarisation along the main transport corridors.
Most places need a wider series of rungs on the housing ladder.
At present there are vast gaps between social housing (much of it for those living on benefits), low-cost, terraced housing in neighbourhoods that often look neglected, inter-war suburban semis that are losing their appeal, and on the edge look-alike estates in places that are inaccessible without a car.
Key issues
There are several questions to be answered, including:
Solutions
To overcome these and other barriers, city regions need to plan creatively across networks of towns and in areas where change is more likely to be successful due to attractive features, for example the Lea Valley in London.
Development frameworks need to incorporate policies that encourage the right balance. For example new high-density housing near town centres could help release suburban family houses for growing families - the key is making better use of existing infrastructure.
Charters as a result of action planning and based on previously successful examples can engage local people in improving their neighbourhoods, and agreeing principles for sustainable growth and well-managed use of resources.
House builders will get away with sloppy layouts and standard house types if they can, so councillors need to be shown more examples of places that really work. Standards need to be tailored to local circumstances.
The key to mixed uses and living at higher densities, is avoiding conflict through good design, regular maintenance, and responsive management.
This means making a budget available that communities can use to build a "pride of place", something that will give them concrete proof of prosperity, possibly through a charge on new developments.
