2.2.5 Consistent project specific featuresWith<strong>in</strong> the programme there are common elementsacross all <strong>in</strong>dividual <strong>condom<strong>in</strong>ium</strong> projects: the <strong>hous<strong>in</strong>g</strong>design typologies, the provision <strong>of</strong> commercial units andcommunal build<strong>in</strong>gs, cost<strong>in</strong>g and quantity survey<strong>in</strong>gsystems, and build<strong>in</strong>g permits and land transferagreements.Condom<strong>in</strong>ium <strong>hous<strong>in</strong>g</strong> typologiesAt the start <strong>of</strong> the IHDP, the Mayor <strong>of</strong> Addis Ababaat the time, Mr. Oqubay Arkebe, approached thearchitecture and eng<strong>in</strong>eer<strong>in</strong>g firm, MH Eng<strong>in</strong>eer<strong>in</strong>g, tocall upon their assistance to draw up schemes for the firsttwo phases <strong>of</strong> the programme. The firm quickly becamethe lead architect-and-eng<strong>in</strong>eer<strong>in</strong>g firm for the conceptdesigns <strong>of</strong> 31 <strong>condom<strong>in</strong>ium</strong> projects.Their design proposals were based on the logic thatbecause the houses themselves could not be <strong>of</strong> such f<strong>in</strong>equality because <strong>of</strong> the low-cost nature <strong>of</strong> the project,ample outdoor green space had to be accommodated onsiteto make residents feel proud <strong>of</strong> their surround<strong>in</strong>gsand ‘remove the stigma <strong>of</strong> <strong>hous<strong>in</strong>g</strong> for the poor’.They attempted to address the <strong>in</strong>evitable difficultcultural transition <strong>of</strong> some occupants <strong>in</strong> mov<strong>in</strong>g fromlow-rise build<strong>in</strong>gs to high-rise build<strong>in</strong>gs throughprovid<strong>in</strong>g a well-designed neighbourhood, provision <strong>of</strong>communal build<strong>in</strong>gs, and a strong connection to land.Unfortunately, the demands placed on <strong>in</strong>creas<strong>in</strong>g thedensity <strong>of</strong> sites resulted <strong>in</strong> the modification <strong>of</strong> the orig<strong>in</strong>almaster plan and their design pr<strong>in</strong>ciples, specifically theloss <strong>of</strong> the orig<strong>in</strong>al clarity <strong>of</strong> the master plan objectivesand a sizable percentage <strong>of</strong> outdoor green space.Densification is the driv<strong>in</strong>g concept beh<strong>in</strong>d<strong>condom<strong>in</strong>ium</strong> <strong>hous<strong>in</strong>g</strong>. The IHDP believes that isgenerally more expensive to create lateral developmentthan vertical development so high-rise <strong>hous<strong>in</strong>g</strong> shouldbe encouraged, especially <strong>in</strong> valuable <strong>in</strong>ner-citylocations. IHDP projects range <strong>in</strong> density from 175 to300 households per hectare 6 . At present <strong>condom<strong>in</strong>ium</strong>blocks are ‘ground floor plus four storeys (G+4) <strong>in</strong> height,<strong>in</strong> some cases five storeys (G+5), therefore avoid<strong>in</strong>g theneed for a mechanical lift, which m<strong>in</strong>imizes associatedconstruction and ma<strong>in</strong>tenance costs. However, <strong>in</strong> themost recent <strong>condom<strong>in</strong>ium</strong> project, located <strong>in</strong> AddisAbaba’s Lideta district, <strong>condom<strong>in</strong>ium</strong> blocks are groundfloor plus seven storeys (G+7). Although this modelrequires an <strong>in</strong>ternal lift which <strong>in</strong>creases construction andma<strong>in</strong>tenance costs, the value <strong>of</strong> the centrally located landnecessitates the higher density to maximise the use <strong>of</strong> the<strong>in</strong>ner-city land on which it is located.There are four unit typologies <strong>in</strong>corporated <strong>in</strong>to each<strong>condom<strong>in</strong>ium</strong> block: a studio, 1-bedroom, 2-bedroom,and 3-bedroom unit types (Table 4). Each unit <strong>in</strong>cludesa bathroom, which <strong>in</strong>cludes a shower, flush-toilet, andbas<strong>in</strong>, and a separate kitchen. Each unit has water,sewerage, and electricity connections.Typically 40 per cent <strong>of</strong> units are 1-bedroom as statisticshave shown that the balance between floor-area andpurchas<strong>in</strong>g price <strong>of</strong> a 1-bedroom unit is the mostFigure 16: Project sites <strong>in</strong>clude unit blocks arranged around outdoor green space.

popular amongst <strong>condom<strong>in</strong>ium</strong>-applicants. The unittypes are distributed evenly across each storey, ratherthan each storey hav<strong>in</strong>g only one type to encourage amix <strong>of</strong> <strong>in</strong>come groups.The same overall design strategy is used across all projects,although m<strong>in</strong>or modifications are made to make eachproject site specific. The site layout <strong>of</strong> the <strong>condom<strong>in</strong>ium</strong>blocks, commercial units, and communal build<strong>in</strong>gsdepends on the specific site, respond<strong>in</strong>g to availableland area, land typography, and required densities. TheHDPO hires new architects through a competitionsystem to avoid monotony between sites.THE ARRANGEMENT OF THE SPACEON A CONDOMINIUM SITE SHOULDACCOMMODATE NOT ONLY GREENAREAS BUT ALSO SCHOOLS,PLAYGROUNDS, AND COMMERCIALHUBS – SPACES WHICH CANPROVIDE ENOUGH REVENUE TOSUBSIDISE THE HOUSING.

W<strong>in</strong>dows anddoors are made from metal frames with s<strong>in</strong>gle glaz<strong>in</strong>g.The modular design reduces construction times andallows for the repetition and adaptation <strong>of</strong> designs acrossprojects. The design utilises standard sizes <strong>of</strong> materialstherefore reduc<strong>in</strong>g costs further (for <strong>in</strong>stance standardhollow brick dimensions are kept to remove the need forcutt<strong>in</strong>g them to size).The Government also explored prefabricated walls fittedwith PVC w<strong>in</strong>dows and doors, as used <strong>in</strong> a Ch<strong>in</strong>ese<strong>in</strong>itiative and has utilised pre-cast concrete elements topromote cost efficiency and time-sav<strong>in</strong>g constructionon-site to help to achieve the target construction time <strong>of</strong>between one and one-and-a-half years per <strong>condom<strong>in</strong>ium</strong>site.
