Somalia's elegant colonial villas were left in ruins by two decades of street fighting among warlords, and the seaside capital Mogadishu was dubbed the most dangerous city in the world.But now, new housing estates are being built amid an economic boom as diaspora Somalis return and newly wealthy businessmen capitalize on the relative peace in the city. Some 7 kilometers outside Mogadishu in a formerly largely rural area, new homes are springing up, with almost 50 houses now ready on an estate, builders say. Mohamed Abdullahi Ali, from Salaam Somali Bank, said it was a "great honor" to back the estimated $20 million project.Construction began in early 2015 and the project was touted as offering commercial returns and helping rebuild the nation."It is a new neighborhood for all Somalis to buy affordable homes by leaving the densely populated neighborhoods of Mogadishu and to come and stay with families here," Ali said."According to our plan, we are going to build 500 homes that can cover the residential needs for 500 families in the first stage, and then will construct more houses."Tens of thousands forced to flee their homes still live in plastic and rag shelters in the capital, sometimes in the ruins of war-shattered buildings, and more than 1 million people are still in need of emergency aid in a country ravaged by famine in 2011, the United Nations says.Car bombs and assassinations are still common, and a 22,000-strong African Union force fights alongside the army to protect the internationally-backed government from attacks by Islamist al-Shabaab insurgents. The streets in the new estate offer a very different vision of Mogadishu. Those returning to Somalia, including investors wanting to start new business in their homeland, say the Daru Salaam estate offers them a more secure place to live. "I came back to this city to buy a new home in the Daru Salaam neighborhood. ... The houses are well built," said Abdiqadar Jimale Roble, 34, who grew up in Sweden from the age of 12 after Somalia spiraled into civil war in the early 1990s. "I have been out of Somalia for a long time but I came back because everybody needs his country, and the country is making much progress," Roble added. "I had to take part in that progress, and everybody should have a house in his country." For those returning with dollars earned abroad, the estate reflects the possible profits to be made even in a still dangerous country.Sadia Sheikh Ahmed, who also grew up in Sweden after fleeing Somalia, said she had helped her relatives abroad snap up property. "Initially we wanted to buy two houses, but now we and our relatives have bought eight homes, scheduled to be completed soon," she said. A two-story house can cost some $130,000, while a simpler bungalow comes in at around $70,000. Those are hefty sums in one of the poorest countries in the world, with a gross domestic product per capita of just $284, according to the World Bank, against a sub-Saharan Africa average of $1,300. Development indicators are "among the lowest in the world", the World Bank says, noting the Horn of Africa nation is "heavily dependent" on aid and remittances. "After more than two decades of violence and political instability, Somalia is on a positive trajectory," OCHA said, while warning the "promising trend" takes place amid a "precarious" humanitarian and security situation."Humanitarian needs remain vast and Somalia's humanitarian crisis remains among the largest and most complex in the world," OCHA added.
