The company will move from its George Street base in the Capital, to a 1,700 sq ft office suite at 33 Castle Street, towards the end of May.
LSH is currently expanding all over Scotland, and has just moved its Glasgow HQ from West George Street to larger offices in Bothwell Street.
Head of operations in Scotland, Craig Maguire, said: “This is another step in the right direction for LSH as we continue to strategically grow and expand our business operations in Scotland.
“By investing in superb new premises in two key cities, we are able to offer outstanding services in both locations as well as serving the rest of Scotland, while providing our staff and clients with a significant sign of our intent.”
Ian Davidson, head of the Edinburgh office said: “The Castle Street office can accommodate upwards of 20 staff and will provide a platform from which to expand the LSH operation in the East of Scotland. We are in discussions with several parties at present with a view to making a number of key appointments in the coming months.’
