A 20,000 sq ft letting at Birmingham Business Park has helped boost the third quarter office take-up figures in the M42 corridor.
Telecommunications firm BT has sub-let the space at Aquarius House from another giant in its sector, EE.
EE has a lease on the grade A building until 2022 and the sub-letting will see BT take over the second floor.
A brace of other deals in the same area are due to be completed shortly.
Alpro, the Belgian-based organic and non-organic food and drink products maker, is taking a new lease on one of the 13,000 sq ft floors at One Trinity Park and engineering firm RLC UK has agreed a similar-sized deal in the same building, meaning it is now fully let.
Approximately 368,000 sq ft of space has been snapped up in the M42 corridor in the first three quarters.
Cameron Thomson, senior surveyor at property consultancy Cushman & Wakefield which worked on the BT letting, said it was possible the locality could see around 500,000 sq ft of lettings during the year.
"There has been a resurgence in demand in the primary out-of-town market in the West Midlands this year," he said.
"Recognising the dwindling supply of high-quality office space, tenants have been busy securing the best space that has been available during the year, including One Trinity Park, and taken advantage of being able to improve their working environments as well as still achieve competitive deals in a market where there is upward pressure on rents and reducing incentive packages are very tangible.
"That trend has left very little good quality space in the out-of-town locations to the east of Birmingham and there is now an opportunity for developers to seriously consider commencing speculative office builds, as they have a good chance of securing a tenant."
