Robert Pinkus & Co has been retained to lease 48,000 sq ft of offices set in 15.5 acres of parkland in Fulwood, Preston.
Harris Park, owned by a local private investor, is situated on Garstang Road, and is an established office complex of 16 office buildings, some of which have become available to let.
The accommodation ranges from 692 sq ft to 8,242 sq ft, with each property allowing views of the park.
Present occupiers include Heartbeat, Youth Justice Board, Uclan and Total Contract Solutions.
Danny Pinkus, partner at Robert Pinkus & Co, said: "Just the names of each building such as The Chestnuts, The Poplars, The Laurels and Holly House conjure up a fantastic location in which to be based and where occupiers can enjoy the natural beauty of the parkland right on their door step.
"The location on Garstang Road means the site is easily accessible, yet, as soon as you turn into the site, you could be miles away from anywhere, making this complex one of the most desirable office developments to come onto the Preston commercial market in quite some time."
Quoting prices are £12/sq ft.
