A roof garden on the top floor provides views across to Edinburgh Castle and the Firth of Forth. The office space boasts a central position in the heart of Edinburgh's beautiful Georgian New Town. St Andrew Square is a desirable and prestigious address, established as the commercial centre for Edinburgh since the 19th century. Most of the buildings still house offices of banks and insurance companies, making it one of the major financial centres in Scotland.
