London Strategic Housing Land Availability Assessment

The requirement for Strategic Housing Land Availability Assessments (SHLAAs) is set out in Planning Policy Statement 3 as a proactive approach to identifying housing land supply. The Greater London Authority have coordinated a SHLAA study to provide an indication of London-wide housing capacity at borough level across London.

The primary role of a SHLAA is to identify sites with potential for housing, consider their housing potential and assess when they are likely to be developed.  The study considers theoretical constraints and probability of development on large identified sites. It does not allocate housing, nor pre-empt or prejudge any future decisions on any particular site or planning application. 

The SHLAA study report outlines methodology and results.
