Mount Stewart is one the most important properties managed by the The National Trust in Northern Ireland. The Grade A listed building sits on the shores of Strangford Lough on the Ards peninsula. An initial feasibility study was carried out to investigate a number of options for reviving the surrounding outbuildings into new visitor facilities as well as upgrading the existing shop. Consultations were carried out with the National Trust, HED and the Planning Service NI. D-on architects were commissioned by The National Trust to convert these existing derelict outbuildings surrounding the main house to create a food and drink kiosk and new visitor facilities. New materials are sensitively set against the existing and the famous light blue Mount Stewart estate colours were then used to harmonise the overall scheme. New access ways into the gardens were created for the public through an existing stone wall. The new landscaping leads visitors to a new seating space as well as a dedicated area for purchasing plants from the garden. Conservation work included the restoration of the historic fabric, sliding sash windows and new interventions around the property.
