There are two ways to build a development business. You can start at the top of the market, where margins are wide, and work down as you gain capacity. Or you can start at the bottom, where margins are narrow, accumulate scale, and work up.
The first route is more comfortable and much more common. The second is what Anas Sefrioui chose, and it has a specific logic. Volume at the bottom of the market buys four things that cannot easily be bought any other way: a land bank assembled before prices rose, a construction organisation that has repeated the same operations thousands of times, a distribution network reaching buyers competitors cannot reach, and a relationship with the state as the counterparty to national housing programmes.
Every one of those assets becomes more valuable when applied to a higher-priced product. Which is precisely what happened. Prestigia (2009) and Coralia (2015) did not require a new company — they required pointing an existing machine at a wealthier buyer.
The sequence also explains the timing of the African expansion. By 2012 the domestic volume position was mature; the marginal return on adding another thousand Moroccan social-housing units was falling. The same capability applied in Senegal, Côte d’Ivoire or Guinea — markets at an earlier stage of the identical demographic curve — earned more.
