The Yorkshire-based property company has taken 20,000 sq ft of prime office space at One Park Row and is embarking on a multi-million pound refurbishment of its space there.
Gilbanks said it wants to create an aspirational, flexible and contemporary working environment for expanding businesses wishing to focus on productivity.
Gilbanks managing director Alex Duckett said: “This is a significant deal for us to start our journey.
“One Park Row is one of the most iconic and sought-after office addresses in Leeds and we have engaged world class designers to transform our new space, spread over two floors, into something very special indeed.
“We are responding to a significant change in working practices over the past decade, which has been driven by the revolution in technology. This has meant the days of the traditional leasehold office are numbered, as are the days of the 9-5 office hours. It is productivity, not desk occupation, which matters.”
The refurbishment programme of One Park Row is due to be completed by September of this year. The building will also feature a health and well-being studio and a sky terrace over-looking City Square.
Other occupiers at One Park Row, which is owned by the Evans Property Group, include Pinsent Masons, Barclays, Rothchilds and Ahead Partnership.
