Hearth Historic Buildings Trust is an architectural heritage, conservation and housing organisation which operates in Northern Ireland and is headquartered in Belfast.
The organisation was established as a joint initiative by the National Trust and the Ulster Architectural Heritage Society (UAH) in 1972 and named the Historic Environmental and Architectural Rehabilitation Trust for Housing (HEARTH). It was established following the passing of the Co-operative and Community Benefit Societies Act (Northern Ireland) 1969.
It has restored almost 40 buildings across its history. It was lead in its early years by Charles Brett who was its first chairman.
In 1991, the organisation changed its name to the Hearth Revolving Fund to reflect its model of restoring properties and selling them to fund further projects.
In 2017, the name was officially changed to Hearth Historic Buildings Trust.
Recent notable projects include ongoing works on restoring Riddel's Warehouse in Belfast.
From 1978 to 2016, the Hearth committee established and ran its own sister charity, Hearth Housing Association which restored at least 100 houses.
In 2016, Hearth Housing Association merged with Clanmil Housing Association becoming its heritage housing division.
