Haigh also designed Marks & Spencer’s store in Church Street.

The house was then enlarged by Liverpool Stock Exchange chairman Thomas Randles Withers, in 1890.

This is the decorative period to which it has been returned, with detailed restoration of plasterwork and fittings in the hall and lounge.

Randles and his descendants lived in the house until 1930, one of only four families to reside there.

Stephen Guy, an association trustee, said: “The house has undergone major surgery to bring it back up to standard.

“We are delighted with the result and think Lowlands looks fantastic. Principal construction was a new roof, strengthening the floors, adding the disabled facilities and installing central heating.

“It is wonderful to replace the architectural features from both inside and out, which were missing for decades.

“There are a couple of smaller rooms still to do, but essentially the work is now complete.

“We are very grateful to the Heritage Lottery Fund for its £1.1m grant and all the other donors who raised the final £100,000.”

Planning the work started in 2003, and Liverpool specialist historic architecture firm Griffiths Thompson was appointed around a year later.

Mr Guy added: “Places like Lowlands help to bring people to Liverpool, and it shows West Derby’s tremendous potential for visitors.”
