IT is one of the charity's more unusual conservation projects - the repair and restoration of a tenement building.

But National Trust for Scotland has stepped in to the maintain the entrance and stairwell of what is one of Glasgow's oldest tenements.

At first glance, the Tenement House in Garnethill appears to be an ordinary middle-class tenement from the late 19th century.

However, inside the rooms are frozen in time and provide a rare glimpse into life in Glasgow in the early 20th century.

Its interiors have been listed by Historic Environment Scotland.

Now the Trust has completed a project to redecorate the common stair of the red sandstone tenement - the first in more than 35 years - to offer a realistic representation of how it would have looked in the past.

Works carried out included decoration to doors, walls and ceilings; plasterwork; repairs and decoration of windows; installation of new glazed frameless external door; lighting alterations; and repairs to external steps and walls.

Fritha Costain, Business Manager for Glasgow & the West at the National Trust for Scotland, said: “The Trust cares for Scotland’s natural and national treasures - even tenements - so it’s only right that we take our turn to do the stair.

"It’s definitely one of the more unusual projects that we’ve ticked off in 2018, but it’s just as important because it sets the scene for visitors coming to experience all that the Tenement House has to offer.

The Tenement House allows those who visit to experience a way of life - tenement living - which many people once shared, but which has now disappeared or changed beyond recognition.

The house features original fixtures and fittings, including a coal-fired kitchen range and gas lighting, along with some of the more obscure items like a ball of soap, turned jet black from years of handling, and a jar of plum jam made in 1929.

With the exception of a few items that were brought in, the entire interior collection belonged to Miss Agnes Toward who lived in the house from 1911 to 1965.

The shorthand typist preserved her furniture and possessions and held on to all sorts of things that most people would have thrown away, making this extensive personal archive a valuable time capsule for visitors today and an important vehicle in showcasing what it meant to be an ‘independent woman’ at that time.

Ms Costain added: “The Tenement House is so significant because its interior is almost completely unaltered from when Miss Toward, the last resident, lived there.

"From the black horsehair chairs, scrubbed kitchen range, household medicines and the recess beds to the working doorbell and gentle hiss of the gaslights, there is so much to discover in this treasure trove of everyday history.

"To find a collection such as this in situ is incredibly rare.

"I’m so pleased that we’ve been able to play our part in protecting this important piece of Scotland’s social and cultural heritage, so that visitors can open the door to early 20th century Glasgow life and see first-hand why we do what we do for the love of Scotland.”
