Housing supply in London reached a low of 17,850 new homes in 2010/11 against the current minimum target of 32,000 per annum.
Although the draft amendments to the London Plan increase the target to 42,000 per annum, this still leaves a shortfall of at least 7,000 homes per annum against the new London SHMA assessment of need for 49,000 homes a year.
The difference between house prices in London and the South East is higher than it has ever been, and we expect this to translate into increased demand in the Home Counties over the next five years.
This case study looks at the LPAs with the strongest migration links to London: the places likely to feel the greatest effect of people moving out of London in search of housing.
The colours on Map 2.1 indicate the difference between locally planned housing targets in each LPA, and predicted need, and the map shows clearly that there is currently little prospect of the shortfall in London being compensated for by surrounding authorities.
Market signals
The Planning Practice Guidance (PPG) requires that housing need assessments pay regard to market signals. In the South East, in which most of the local authorities in Map 2.1 are located, and where demand is higher, Holmans’ projections indicate a higher need for housing, equivalent to expanding housing stock at a rate of 1.1% per annum.
In most of these LPA areas, market signals indicate high levels of demand relative to both the South East and national averages, indicating that need in these areas is higher. However, most of the LPAs have set themselves housing targets below the average required.
Authorities within the more affordable, lower demand areas to the east of London (Thurrock, Dartford, Gravesham) are amongst the few planning to deliver relatively high numbers of houses, in excess of 1.04% of stock. Conversely, in Surrey, Berkshire and Buckinghamshire, where there is higher demand, housing targets are below this rate.
We conclude from this analysis that there is a need for application of a broad ‘duty to co-operate’ across a sub-regional area in the South East, comprising London and its adjoining authorities, and also those locations with a close connection to the London Housing Market Area within roughly an hour’s commuting time of the capital. It is within this sub-region that there maybe a particular role for New Towns to contribute towards meeting some of the unmet need.
