The company, which provides software and hardware for the oil and gas industry, has bought the two-storey building outright, having previously leased part of the premises.
The new 3,800 square foot facility, which features a training suite, will allow the business to build upon a period of recent success.
The £600,000 investment has been supported by Clydesdale Bank.
Motion said staff numbers had risen from 18 to 25 in the past year, including four personnel who have joined the company in the past six months.
Managing director Stephen Burt said: “Despite the challenging conditions around the oil and gas industry at present, we are continuing to experience a high level of demand for our products and services from North Sea businesses and clients as far afield as Houston, Dublin and Abu Dhabi.”
