When a family is living in an apartment together, it is essential for each family member to have his or her own space. At times, it may not be possible for every child to have his own room or every parent to have a private office, but each person must have at least some space that is their own. In this family apartment in St. Petersburg, from the designers at Art Studio Design, each room has its own distinct feel and each family member has a space that is unique where they can retreat whenever they need to get away.
