In 2015, Janna worked on artist's impressions of an initial concept design for the transformation of the main building at The Sustainability Centre, in East Meon, into the New Learning Centre.  The main building is the hub and focal point of the Sustainability Centre, and currently houses the main reception in a public foyer, toilets, offices, cafe, conference room and indoor classroom space.  The building currently has no insulation, a leaking flat roof and has very poor energy efficiency, but the aim is to retrofit rather than replace the existing building.  The concept here is based on an organic structure encapsulating the old HMS Mercury building, with skeletal roundwood legs pinning down the great curved wildflower shell.
