Introducing Kingsbrook: giving people and nature a home

To tackle the housing crisis, there is consensus that we need to build a lot more houses - maybe up to 200,000 a year by 2020.  We don't disagree.   We need affordable homes and we need to accommodate the expected growth in the English population - another 8 million by 2040.

But we do want these houses to steer clear of sensitive sites like Lodge Hill (now, thankfully, subject to a public inquiry - see here).  And, we also want developers to create communities which people want to live in and where they have contact with nature. 

This is why I am so excited by Kingsbrook - a sustainable urban extension to Aylesbury which includes 2,450 new homes, new schools, community facilities and employment land.

Much contemporary development on greenfield land makes provision for green infrastructure, following the example of developments such as Cambourne, close to where I live in Cambridgeshire. Yet, what marks out Kingsbrook as distinctive is the extent and quality of the planned green infrastructure, and the way that wildlife-enhancing measures are embedded into the fabric of the built environment, not just left to the public open space.  Kingsbrook’s green infrastructure will include orchards, hedgehog highways, newt ponds, tree-lined avenues, fruit trees in gardens, bat, owl and swift nesting boxes and nectar-rich planting for bees. It also includes more than 100 hectares of wildlife-rich open space, accessible to all residents.

The plans are impressive and it almost makes me want to move to Aylesbury - I have my eye on one of the plots close to the proposed sand martin bank.

I met the team behind the project a fortnight ago.  It was good to see the plans and to go on site to get a sense of what will be created.   

The project is over a decade in the making and is principally a partnership between Barratt Developments and Aylesbury Vale District Council.  The RSPB became involved in 2011 and since then we have deepened our collaboration both with the project but also with Barratt as a business.

I hope and expect that this project - with construction due to begin this summer - will become a beacon for future housing developments.  While meeting future housing needs, we must find ways to meet the needs of wildlife as well.  Kingsbrook gives us clues as to what is needed for this to happen.  Here, I outline what I think are the key lessons for housebuilders, policy makers and local authorities.

Lesson 1. The housebuilder, Barratt Developments, is concerned with profit margins rather than just chasing the volume of output. Barratt believes that people will be attracted to a nature-friendly development and that it makes economic sense for them. They may see this either through a price premium or a faster rate of sale, or possibly both.

Lesson 2. Previous planning policy on eco-towns (2009) required “Forty per cent of the eco-town’s total area should be allocated to green space, of which at least half should be public and consist of a network of well managed, high quality green/open spaces which are linked to the wider countryside.” Kingsbrook shows that 50% green space, excluding private gardens is achievable. 

Lesson 3. The local planning authority, Aylesbury Vale District Council, recognises the value of nature to people and employs ecologists in a Green Spaces Team (as featured in our report Planning Naturally). This enables the council to get the most ecologically out of developments such as Kingsbrook and gives it credibility in refusing proposals that don’t meet the high standards required. AVDC’s Green Spaces Team supports itself financially by carrying out work for other local authorities. This is one way that councils can get access to the right expertise, but it does mean that the expertise is spread thinly. The Government needs to consider how specialist skills such as ecology are best supported by local authorities.

Lesson 4. Kingsbrook shows what can be achieved by willing partners even without an up-to-date local plan in place. For most planning authorities, the best way to ensure that development is nature-friendly, is to have planning policies that set high standards. Local authorities such as Exeter City Council have led the way with high design standards in supplementary planning documents, allowing them to require developers to do more for nature. Again, there are more details in Planning Naturally. Perhaps the biggest barrier to other local authorities following suit is a perception that such policies would prove a prohibitive cost burden to developers. Kingsbrook shows that this need not be the case, but rather that nature-friendly development can add value.

Kingsbrook is a 15 year project, but its impact could be immediate if others become curious about their ambitions.  The pioneering team behind this project deserve huge credit - they offer hope that we can give both people and wildlife a home.  With just 80 days until the General Election, I hope that politicians sit up and take note.

What do you think about the Kingsbrook development?

It would be great to hear your views.
