The company had outgrown its home in High Street, Poole, but has now bought the 16th-century building next door.
The firm already employs 30 people and managing director Lloyd Banks said the expansion would give them the space to recruit up to a further 28.
“The economy is doing really well, lots of people are hiring and we have been growing very quickly,” says Banks.
“Extending into next door is facilitating us being able to expand. It doubles the size of our office space and we will grow into that space over the next 18 months to two years.”
Rubicon provides general recruitment services as well as specialising in sectors including engineering, IT, marketing and creative and digital industries.
The company’s new building is Grade II-listed and has historic features including an early 17th-century patterned ceiling and a stone fireplace. The firm worked with NatWest relationship manager Craig Cotton to secure a commercial mortgage to purchase the building.
“We love the fact it is a listed building,” Banks adds. “We are part of Poole – we have been trading for 30 years and while we operate nationally it is all done from our office here. Poole is our home.
“To have an historic building of interest to English Heritage under our stewardship is awesome.”
