THE new owner of a city centre shopping mall in Edinburgh has signed up two new outlets as it prepares to go through a revamp.

Princes Mall has poached the Post Office from its rival, the St James Centre, and Sainsbury's has also signed up for the mall next to Waverley Station.

The London-based development firm Catalyst Capital bought the mall from the former Rangers owner Sir David Murray's company earlier this year as it was being sold as part of a ten-property portfolio from Premier Property Group for £43.1 million.

PPG is thought to have paid £37m ten years ago.

Catalyst Capital is spending £3m for a "transformative refurbishment" with business continuing as usual at the mall, it said.

TIAA Henderson Real Estate - formerly Henderson Global Investors - which owns the St James Centre in Edinburgh, is due to begin work on its £850m revamp that includes the removal of an "eyesore" tower next year.

TIAA, also London-based, which bought the building in 2006 for £184m, has plans that include enveloping the John Lewis building, by the new St James Quarter, with more than the 70 or so shops it currently has, flats, offices, cafes, a public square and at least one luxury hotel planned next to the playhouse Theatre.

The firm is due to outline more details of its plans later this month when it holds a public forum at the Glasshouse at Greenside Row.

A spokesman for Sainsbury's said it is to open a convenience shop in December.

The Post Office is due to open in the mall on Monday November 3.
