The urban structure of Helsinki is becoming increasingly dense, as an outcome of the City of Helsinki’s commitment to the goal of 5,500 new housing units completed in the Helsinki area each year.
Space for new housing is scarcest in the Helsinki city centre. New housing is often built in attics, while commercial centres expand underground.
In addition to attics, housing companies are interested in putting homes into buildings in their courtyards, as a means to pay for expensive renovation projects. Offices can also be converted into homes.
