Neighborhood of Seventy Low Cost Houses
1986 to 1991
Santa Rosa de Cabal, Risaralda, Colombia
Low Cost Housing, Realized
, Construction completed in 1993; C.E.S. involvement ended in 1991
Seventy low-cost houses in 4,2 acres, designed by families, and partially built by families, as part of the self help construction process of Construyamos, the largest self help cooperative in Colombia, with a total construction volume of 50,000 houses per year. This project was to be a model of an entirely new kind of low cost housing process, in which a more organic community can be achieved, without increasing construction cost.
The project was built in Santa Rosa de Cabal, under the guidance of C.E.S., on a sloping hillside, in a rural area. It includes 70 houses, ranging in size from 100 m2 to 139 m2. The houses are two-story main volumes and one-to-two-story secondary volumes. The two-story volumes shape the streets, and the secondary volumes help define a garden at the back.
In the Santa Rosa project, all the houses are different. The overall configuation of the site and the forming of the streets in parallel with the “contribution” of each house to the shaping of public spaces, were conducted on the land by the members of C.E.S. with representatives of Construyamos and the housing group. It is only after each individual plot had been “set” in relation to the larger whole, that the individual families took over, and laid out their houses on the land, with a C.E.S. “layout coordinator”.
Client:
The Royal Architectural Institute of Canada (RAIC) - John A. Neilson, Professional Advisor; "Construyamos" La Camara De Vivienda Popular Por Autogestion Communitaria - Mr. Hernan Mesa, President
C.E.S. staff:
Christopher Alexander, Ingrid Fiksdahl-King, Artemis Anninou, Kleoniki Tsotropoulou, Fanta Lawrence, Seth Wachtel, Jeannie Radcliffe
Contractor:
Built by the families and local subcontractors under the management of Constuyamos and the Center for Environmental Structure
Sponsor:
World Bank; Canadian Government (CETA);
University of California
Design and construction process:
The step-by-step process on design consisted of discrete design phases, in the following order.
1) Site: The overall configuration of the project arose from the qualities and features of the land.The layout was done directly on the site, working with stakes and earth-moving equipment, in parallel to working with models. Common space in the form of central terraces, formed the central axis across the contours. Roads run on contours, perpendicular to the axis. The final layout was surveyed and presented as an initial subdivision map.
2) Streets: The forming of the streets was tightly connected to the "contribution" of each house to the formation of a larger whole, this being a public space --street, alley, terrace. Simple rules were followed with regards to the location of the main volume of each house and the determination of main levels -- sidewalk, front garden and main floor. As a result, the house volumes form a continuous street wall behind a front garden, while both house volume and width of parcel vary. The result of this phase was, besides giving shape to the streets and open public space, the plan and sections of foundation and retaining wall for each lot, and consequently the levels of the streets. This process was conducted with stakes on the site by the members of C.E.S. with representatives of Construyamos and the housing group. The detailed layout and lot subdivision was surveyed and presented.
3) House Design: Individual families working with a C.E.S. "layout coordinator" took over, working with stakes for the layout of their house directly on the individual site.
Phase One of the House Layout: The first phase involves designing "five major centers": garden, veranda, comedor, final configuration of exterior volume, final configuration of front yard.
Phase Two of the House Layout: The second phase is devoted to the interior layout of the house in detail: entering sequence, kitchen, sala, main stair, etc.
4) Construction: Members of the families were involved in the construction of the project. The first house was completed in Nov. 1990 to serve as a prototype house for the project as a whole.
Project stages:
Pattern language for the project by clients and C.E.S. Layout on the site by clients and C.E.S.
Layout on the site by the families and C.E.S.
Generative rules for urban growth process
Design Development and Building Permit drawings done after layout
