An armchair and standard lamp have been in the Mackintosh-designed living room for 110 years and have been on loan to the Trust.

However, these two pieces are now up for sale and the Trust is attempting to purchase them to ensure that they can stay where they belong.

In a letter to Trust members, Lorna Hepburn, Hill House property manager, said: “The drawing room where these items were lovingly placed 110 years ago is a favourite area for visitors and is definitely the most important interior space at the Hill House.

“The armchair and standard lamp are an integral part of the design of this room and add to the overall ‘wow’ factor for visitors.” The charity has already secured £75,000 in funding from The Art Fund, The Monument Trust and the National Museums Scotland National Fund for Acquisitions, but needs a further £25,000 in public donations to secure the pieces for future.

Lorna added: “The recent fire at Glasgow School of Art reminds us that the limited remaining legacy of Mackintosh’s work is both vulnerable and precious. If we were to lose both the lamp and the armchair, these iconic designs would quite likely be made inaccessible to the public.” The Hill House is Mackintosh’s only domestic commission that members of the public can visit. Built for the Glasgow publisher Walter Blackie and his family between 1902 and 1904 this much-loved family home stands as a reminder of how family life and world-class architecture can co-exist.
