A report summarising the findings of an international design research programme, the Portsmouth Elephant Cage (2016-17), which evaluated and explored the current proposals for sea defences along Portsmouth’s Southsea frontage. A video presentation is available through links on the following page.

The investigation raised a number of significant issues. An alternative design, proposed in this report, illustrates a strategic approach that can further enhance the value, amenity, environment and ecology of Southsea common, whilst delivering a more sustainable future Portsmouth. The report recommends actions forward to address the apparent shortfalls with the existing proposals.
