The Regus Group PLC, a British company that offers office space for rent worldwide, is expanding in Atlanta, betting that the city is well positioned to weather the recession.

Regus has leased 21,000 square feet of office space at Atlantic Station in Midtown that it will subdivide and lease to other tenants, said spokesman Dennis Watson.

The space will include 102 offices with a boardroom and videoconferencing studio. Regus has 23 other office locations in metro Atlanta totaling 600,000 square feet of space.

The company offers an alternative to a traditional office lease, a product known as a “virtual office.” This allows customers to have an office address and even a secretary, but only use the office space for a few days a month at a greatly reduced rate.

For example, a company could get an address at Atlantic Station for $375 a month with use of an office for five days each month. In announcing the Atlantic Station expansion, Regus cited five reasons why Atlanta is a good place to do business, including Hartsfield-Jackson Atlanta International Airport and the headquarters of giant international companies such as Coca-Cola Co., Home Depot Inc. and United Parcel Service Inc.

Regus, based in Surrey, England has 400,000 clients worldwide, including Internet search engine Google Inc., in 75 countries.
