In October 2001 MAST submitted the winning entry for the Scotland wide Sustainable Housing Competition, promoted by Castlehill Housing Association, for a site at Inverurie, Aberdeenshire. The final scheme of 34 houses is a development of the competition entry and was completed in 2004.

The design concept seeks to create a settlement within the fairly challenging surroundings and achieves this by placing the houses on the perimeter of the site, overlooking a small park and play area.

The design move was to create wide frontage plans, to allow cross ventilation, solar gain and flexible internal planning, plus the provision of integrated sunspaces.

The main construction features include triple glazed windows, 300mm insulation to walls and roofs, communal heating and prefabricated timber cassettes, the latter being developed in collaboration with a local timber kit manufacturer.

Winner of the Chartered Institute of Housing Conference environmental innovation award for 2004.
