After the Second World War an intense period of modern housing construction started in Sweden, which suddenly changed the circumstances of everyday life for a great number of the Swedish population. The tenants were offered apartments equipped with central heating, kitchen with fridge and electric cooker, and bathroom with bathtub. These dwellings gave rise to new experiences for everyone who moved in. By ordering their things and establishing new everyday routines and habits, people appropriated this new and unfamiliar space and made it one with their ongoing life. In this process of spatial organisation and routinisation new borderlines were drawn and new meanings were given to categories such as private-public, indoor-outdoor, home-outer world, us and them. Applying a theoretical approach from phenomenology, based on life story interviews with people who experienced these modern apartments in their capacity as the first tenants, the article elucidates how people through their daily habitual actions, in interaction with things and consociates both delimited and positioned themselves in connection with a wider world. Namely, how theyestablished a relationship between private and public realms, home and not-home, inside and outside, “us” and “them”, and, furthermore, how they transformed an unfamiliar space into a familiar place, a place they could call their own.
