This article describes our current research focused at the development of an integrated planning support system for the low-income housing production, using as exploration field the participative-planning strategies, particularly implemented by the progressive housing program in Concepción, Chile. Setting our sights on the implementation of modern IT (Information Technology) into architectural field to support the entire planning process, it will be exposed the general deficiencies, diverse IT-tools, their combination possibilities and their practical contribution in order to prove the feasibility of a computer-aided system within a new concept of housing planning.
