Grosvenor has let two units at One Park West in Liverpool city centre and is close to completing another deal on its development.
A 2,000 sq ft unit has been let to Café bar chain Nosh & Coffee, while healthcare organisation Bupa has taken a 1,800 sq ft unit fronting the Strand.
Grosvenor has said another deal is near completion, which is a restaurant unit of 2,860 sq ft that is currently in the hands of solicitors.
These lettings see the development almost fully occupied, with interest from a number of potential tenants in an additional 5,500 sq ft of space, leaving a 400 sq ft kiosk available to rent.
Guy Butler, project director at Grosvenor, said: "These commercial lettings demonstrate One Park West's success in terms of sales in the first quarter of this year. We are thrilled to welcome such prestigious tenants on board."
The deals follow Think publicity's recent move, with the agency having acquired 1,044 sq ft of space. In addition, architect and design agency BDP has let an 800 sq ft suite at the development, while Grosvenor itself has taken on a 1,400 sq ft unit.
King Sturge is the agent on the building. Details of the rental agreements were not disclosed.
