Over the past decade most town and city centre regeneration plans have been based around building or redeveloping a shopping centre. We have seen transformative schemes in Liverpool, Birmingham and Leicester, amongst others.Seven years ago, when we held the first of our annual Northern Regeneration Summits, experts were confidently predicting that retail opportunities in the big cities would soon be exhausted, and the next places to benefit would be the 'second tier' northern towns such as Blackburn, Burnley and Barnsley.
Many towns responded by planning wholesale retail-led regeneration schemes for their centres. Now, however, commentators say that the stagnant economy and rise of internet shopping have brought almost all such schemes to a halt.
Indeed, some experts argue that the trend to internet-shopping, combined with other trends such as the big fashion retailers' increasing preference for concentrating their outlets in the 60 or 70 most lucrative centres, means that wholesale retail-led redevelopment will never again be a viable option for many smaller towns.
Last week I met Chris Goddard and Gerry Hughes of the consultants GVA Grimley. They are among the commentators warning that too many councils are planning on the basis of outdated assumptions about never-ending retail growth in town centres.
Towns that are struggling to get big retail schemes off the ground may have to consider going back to the drawing board, they say. Among the options they could consider are:
1) Breaking a large retail scheme into several smaller parts.
2) Changing the phasing of the scheme's development, with the aim of starting work on the most immediately viable component. Hughes said that they days had gone when developers would gamble on the viability of the first phase of a development in expectation of making their return on the second or third.
3) Accepting a different type of retailer to anchor the scheme than that originally proposed. They said some schemes which had lost department store tenants have been attracting interest from supermarket chains.
4) Targeting alternative uses to retail. Stockport Council, for example, is apparently reworking retail-led plans to focus more on leisure.
5) Redesigning mixed-use schemes so that the mixing becomes vertical rather than horizontal. For instance, this would mean building offices next to homes or shops, rather than below or above them.
6) Focussing on attracting independent retailers. Goddard, however, warns that meeting such objectives requires a landlord with a "controlling mind" who is prepared to forego short-term rent revenue to achieve the right mix of shops long-term. Local authorities could make stipulations about the initial lettings on new schemes, but can't do much more than that, he says.
Some of these ideas will stir misgivings among some regeneration practitioners. For example, the obvious danger of rephasing, or changing from horizontal to vertical mixes, is that the most profitable part of the scheme gets built, but no progress is made on other important elements - perhaps the elements that prompted the public sector to back the scheme in the first place.
But, with vacancies in town centre shops continuing to rise, and internet shopping continuing to grow, it is surely right that councils should be increasingly be looking beyond large-scale retail when planning how to regenerate their town centres.
Do you agree? Can you point to concrete examples out there of where public bodies have adapted their approach to take account of this new reality? Hughes and Goddard have promised to come back to me with their own examples, but in the meantime it would also be great to get some other perspectives. Or do you think that the rise in shop vacancies is no more than a blip, and that ambitious retail-led redevelopment is still a sensible and viable medium to long-term option for many towns? Either way, it would be good to hear your views.
