Following the acquisition, the company plans to invest a further £1m to convert the property into 13 apartments for rent, which will be served by a private road through the park.

The new flats in the Mansion House property are expected to be ready by the end of next year.

To date, Spectrum Properties has invested tens of millions of pounds in saving and repurposing properties of recognised architectural merit in Glasgow.

The firm has previously been involved in preserving a range of properties, such as Victorian warehouses in French Street and Carstairs Street in Dalmarnock; the historic Shakespeare Street public school in Glasgow’s West End; the façade and towers of the Golfhill School in Dennistoun; and a factory on the 19th century Dixon’s Blazes Industrial Estate.

Bill Roddie, managing director at Spectrum Properties (pictured above), said: “The Mansion House is a quite spectacular property, built in a distinctive Scottish style and set on the summit of what was then the Dunlop family’s private estate.

“As ever, we plan to undertake a sympathetic restoration of the entire property, keeping it in its original form and retaining the 13 residential apartments currently onsite. 

“When completed, Tollcross House will be the centrepiece of the park and will complement other improvement work, such as the £1m restoration of the Winter Gardens glass house, which is a classic example of its kind.”
