a/(one's) place of business

The physical location from which business is conducted. This building has been our place of business ever since my great-grandfather established the company in 1875. It can be tricky working from home, but it helps having your place of business be confined to one specific room in the house. This is a place of business, so I'll thank you not to behave so rambunctiously!
