"lifestyle" is a term I personally use to identify modern commercial architecture and building styles. Originating from "lifestyle" centers it refers to buildings that are bright inside and have very casual decor (corny banners with smiling people included) to be appealing to people from all walks of modern 21st century life. For example a modern strip mall with fake windows and decorative trimming along the roof line that you would normally see on a modern house or piece of home furniture rather than a commercial building like below vvv
Or just like you said, a modern drug store with its murals along the walls with smiling people and phrases like "great prices for YOU daily!" As well as banks which are now alot less formal and furniture as well as interior decor that you would normally see inside of a middle class suburban home.
Place Ville Marie circa 1962 for example was NOT a "lifestyle" bank with its towering marble walls and floors dimly lit by pot lights creating a classy high end professional feel. It was a place to get dressed up to go too. A suit for gentlemen and a dress with white gloves for the ladies. Very upscale professional and even a bit intimidating if you weren't used to that kind of environment. Its what I would expect of a bank even today. sadly people today would rather walk around in jeans and a stained t-shirt instead of get dressed up and look decent to go out shopping or run errands. It shows how much society has regressed in the past 50 years.
