The practice has built up a particular interest in the conservation of modernist era buildings. In 2006 Mark Hackett was a co-author and the main photographer for the publication Modern Ulster Architecture published by the Ulster Architectural Heritage Society. (Evans, Hackett, Hall, Larmour, Rattray) In the course of making photography and drawings for this publication he gained a first hand knowledge of the modernist and Twentieth Century buildings of the region.

The practice has guided and helped a number of organisations and communities in the management of modernist and Twentieth Century buildings. This includes strategic advice at business case stage through to the completion of detailed renovation projects.

In particular where existing buildings of historic merit require modern additions, the practice has gained an award winning reputation for careful design. The urban, social and economic case for the retention of any building of merit is something we advocate.
