Ugly steel-and-glass buildings pollute Addis Ababa

The Economist points out that office and residential buildings that are currently being built in Addis Ababa contribute to pollution and are vulnerable to earthquakes. Most of these buildings are constructed by Woyanne-affiliated companies such as Sunshine Construction with little or no  quality inspection.

(The Economist) — AMHARIC has no precise word for architecture, but it needs one. Ethiopia’s capital, founded by Emperor Menelik II in 1886, now has 4.6m people but that figure may well double by 2020. Dirk Hebel of Addis Ababa’s revamped architecture school says that “the first thing we do is to sit down with the students for a day and explain what [it] is”.

According to the UN, Addis has one of the higher densities of slum dwellers in the world. But their geographical pattern is unusual. Most African cities separate fairly neatly into poor and rich areas “like a sunny-side-up egg”, with slums spreading out from the rim, says Mr Hebel. But Addis is “more of a scrambled egg”. A lack of crime and a tradition whereby the rich seem to tolerate the poor living among them mean that Addis’s slums often lie in the seams between office buildings and flats in the more affluent parts of the city.

Some cash for the overhaul of the architecture school has come from a technical institute in Zurich, known by its initials ETH. Mr Hebel and Marc Angélil, head of ETH’s architecture school, have co-written a book that explores the city’s many architectural styles. Ministries built in Ethiopia’s Marxist period (1974-91) were kit models from the Soviet Union. Fascist-style buildings built during the Italian occupation (1935-41) have often proved more suitable. Messrs Hebel and Angélil think African architects could learn from the way the Italians allowed streets to radiate out from grand central buildings.

What the architects call this “mixity” of styles may offer a chance to tackle the scourges of traffic gridlock and pollution. The city still has some open spaces that could be artfully filled in if public transport and the water supply were improved, along with the planting of indigenous trees and grasses.

The needs for good planning and appropriate architecture outside Addis are just as big. If projections of population growth come true, Ethiopia may need 20 new cities of 5m people each by 2050. Pilot projects, including one by another Swiss architect, Franz Oswald, are in the offing.

But a recent building boom in Addis has not improved the prospects for a well-planned, pleasant city. Speculators with government connections have put up ugly steel-and-glass tower blocks with glass façades that increase the need for polluting air conditioning. The cement and steel have to be imported and the buildings may be more vulnerable to earthquakes. Smaller ones in local stone with traditional guttering that collects rainwater would be a better bet, Mr Hebel reckons. Among other things, the use of local materials might cut building costs by more than a third.
