Since 2012 Yppärilä has concentrated on depicting built environment with her signature three-dimensional painting technique. Her technique
blurs the line between painting and sculpture.
The buildings presented in her work are often common-looking places within their local environments. They are places that might seem mundane to the eye of a trespasser, such as bars and weathered corners of neighbourhood groceries, but they also have alternate functions as social gathering points for different kinds of communities. On the other hand, some of the places are already abandoned or about to be bulldozed. These buildings are part of life soon to be forgotten.
Yppärilä’s interest to buildings is primarily sociological: buildings are an expression of lived history and the present moment, of the values and changes in society, and of the social environment of individuals. Detached from their contexts, buildings are no longer places of passage but objects that can be viewed as portraits of society and its members.
Yppärilä's work also includes oil paintings, watercolours and video art. Her works often reflect on the activities of the individual and society, loneliness and power, with a gentle melancholic touch.
She has works in collections such as the Aine Art Museum (FI, Kiasma Museum of Contemporary Art (FI), the Tampere Art Museum (FI), the Oulu Art Museum (FI), the Turku Art Museum (FI) and the Pori Art Museum (FI).
