The last office space in the latest International Finance Centre block has been let.
Butterfield will move into IFC 6 when construction is finished.
The bank has signed a deal to lease 6,800 square feet - or 10% percent - of the third building.
Lee Henry, CEO of the Jersey Development Company says it's the first time an IFC building has been 100 percent pre-let and that it demonstrates the strong demand for modern and efficient offices.
Richard Saunders, Butterfield’s Managing Director of the Channel Islands & UK, says they are looking forward to moving in early next year.
"As our journey to provide banking services to local residents progresses, building on our experience of serving the corporate community here in Jersey, the new location on the ground floor offers modern and easy-access office space - a plus for both our clients and colleagues.”
Building of IFC began towards the end of 2021.
It is five storeys high, will have a restaurant on the ground floor, and include the extension of Trenton Square. It is due to be completed by the end of this year.
The 4,000 square feet of retail space on the ground floor - including al fresco dining areas - is now being promoted to the food and beverage industry.
