The not-for-profit organisation is in the process of planning Public City, a show at its Building Centre base, together with a series of talks.
It will focus on recent developments in the public realm in London, such as mayor Ken Linvingstone's '100 Squares for All' pledge.
NLA organisers are now asking architects to submit examples of their work in the capital's public spaces.
These could include recently completed or planned schemes, initiatives or concepts that 'address public-realm issues in London from an inclusive, wider, and innovative perspective'.
The Public City show will run from 18 January-3 March 2007.
