Software company Datalex and planning consultancy Barton Willmore are the first office occupiers to sign for space in Tower 12 in Spinningfields, Manchester.
The former Manchester House building is being refurbished by Allied London as the latest phase in its extensive city centre development.
Michael Ingall, chief executive of Allied London, said: "Tower 12 is set to become another significant landmark on the Spinningfields estate and securing our first two commercial occupiers shows the new product is already creating a market for itself well before completion. The building is going to be a very special place to work and do business by the summer.
"Tower 12 is more than just work space. It is complemented by Avenue North beneath it and we have no fewer than five restaurants under offer, all to be operated by independents with fantastic track records. It goes to show that if the product is carefully considered and designed, it can be successful and attract different commercial operators who see and share our vision."
OBI Property is the letting agent on Tower 12. Will Lewis, partner at OBI Property, said: "Despite the challenging economic climate, it is testament to the intelligent design of the space created at Tower 12 that we are able to secure lettings before the project is complete. Occupiers in Manchester appreciate the latest Spinningfields work space and there is strong interest in the remaining space."
The details of the deals were not disclosed.
Barton Willmore is the largest planning consultancy in the UK and opened its first Manchester office last year. The company is enjoying rapid expansion and is moving into Tower 12 as it increases its team.
Dan Mitchell, Barton Willmore partner in the Manchester office, in 3 Hardman Street in Spinningfields, said: "We are very excited to move into a new office space to accommodate our expanding team in Manchester and take advantage of the many opportunities across the North West. Tower 12 will give us a high quality contemporary space in which to grow as a business in the heart of the city."
Datalex is one of the world's leading providers of software to major airlines and travel agencies including Air China, Aer Lingus, STA Travel, Trailfinders, United Airlines and The Co-operative Travel. Datalex was attracted to Tower 12 because it wants to provide an inspirational and forward thinking working environment for its staff.
Mike Naylor, director of business development, Datalex, currently in Bank House in Charlotte Street, said: "We're really impressed with the space at Tower 12. Its thoughtful design will provide a great working environment that will allow us to continue to innovate for customers. We're looking forward to moving in."
