Ms Liz Davidson O.B.E.

Since graduating from Edinburgh College of Art as a post graduate in Architectural Conservation, Liz has been involved in most aspects of Scotland’s built heritage. Most recently she was head of Heritage and Design at Glasgow City Council.

Previous to this she led the Heritage Lottery funded Townscape Heritage programme to regenerate the Merchant City. Earlier posts included that of director of Glasgow Building Preservation Trust, a charitable property developer rescuing and bringing back to life numerous historic buildings including St. Andrew’s Square Church, the Tobacco Merchants House, Wellpark Enterprise Centre and the iconic blue ‘Tardis’ police boxes.

Whilst at the Trust, Liz also pioneered Doors Open Day which introduced the UK’s first free mass architectural participation event. A two year secondment to Historic Scotland also saw the development and launch of the multi million pound Conservation Area Regeneration Scheme (CARS) programme. Previous to that, case work across Scotland for the Scottish Civic Trust has given Liz an extensive background in local vernacular architecture in addition to trustee positions on the former Historic Buildings Council for Scotland, the Architectural Heritage Fund and Strathclyde Building Preservation Trust.

As former chair of the UK Association of Building Preservation Trusts Liz gained a deep insight into both those organisations.
