Planning data

Know the score Land and planning potential is so complex to value that many think a computer could never do it reliably – but could software now being developed transform the process?

Daniel Mohamed

Developers can spend significant sums on due diligence before even securing an option on land, in the hope that it might have development potential. This process is repeated for each property transaction on every matter from legal covenants to reviewing the local plan, whenever property comes on to the market, or even speculatively beforehand. But imagine that all the data you need to analyse a site, whether related to local politics or endangered species, was available in a format that your computer could process in seconds, and instead of poring over documents you could quickly understand the site’s strengths and weaknesses. That’s what property technology start-up Urban Intelligence

hopes to provide: for almost five years, the team has been working to digitise planning policy and other data necessary for traditional site appraisals. The resultant SiteScore aims to offer a comprehensive digitised planning policy map of England and Wales, covering everything from conservation areas and article 4(2) directions to special landscape areas and community infrastructure levy (CIL) zones. It is a similar concept to a credit rating, in that it analyses evidence in data about a land parcel to calculate the likely implications for development potential, producing a range of scores that seek to measure sustainability and viability. Using an individual land parcel as its frame of reference, the sustainability
