Atha Developments, established by identical twins Jack and Tom Atha, has seen recent growth after becoming the biggest supplier of Luxury student accommodation for Teesside University.
The firm will now be based entirely from Darlington to cater for an upcoming roster of work in the area.
Jack said: “We feel Business Central is the ideal environment to expand our business. The size of the office space is perfect and it’s a lovely brand new building in which to meet our clients.
"Tom and I both have a passion for designing buildings and seeing them come to life, and enjoy the challenge that property development brings.”
Future plans projects include plans for luxury family houses in Middleton-St-George, a 40 bedroom student development in Middlesborough and two commercial sites in Darlington.
Centre manager Vanessa Wood added: “It's fantastic to welcome another growing business to our Centre. The passion Jack and Tom have for what they do is second to none.
"There are lots of improvements taking place in Darlington and I am delighted to see Atha Developments are going to be a part of them. “
