Peru has experienced steady growth in its construction industry since the late 20th century, driven by rising incomes, higher public and private investment from economic growth. This growth is due to increased domestic demand from population and economic growth, higher private investment supported by public investment, and improved access to financing for housing. Housing construction has increased particularly for low and middle income families through government programs. In 2012, over 44,000 housing units were constructed, a 10.9% growth, with over 21,000 homes sold in Lima alone. The construction boom is expected to continue attracting financial investment.
