Abstract
In 2005, the rural housing deficit in Colombia was 1,600,000 units, which is equivalent to 68.25% of the total households. This very high number shows the difficulties faced by public policies on rural housing. This deficit is partly due to logistical problems related to the supply of materials and complexity in construction processes. It is necessary to explore new alternatives to offer more and better homes at lower costs. The research project presented in this manuscript started in 2013 as an initiative to reduce the housing deficit. It proposed to build a rural housing prototype integrating digital manufacturing processes. The performance of part of the structural and enclosing system was evaluated during a first iteration process to include changes in a second iteration later. With the adjustments to the design process discussed here, the prototype is expected to be built and tested to measure its efficiency and functioning.
Highlights
Public policies on rural housing in Colombia face complex difficulties due to very high housing deficits
It has been demonstrated so far that an integrated digital manufacturing process applied to rural housing is viable, combining technical-constructive variables, context variables, and user variables
The second iteration - as part of a continuous process of evaluation and learning - showed a wide margin of optimisation and improvement in performance, which the housing prototype can have
Summary
Public policies on rural housing in Colombia face complex difficulties due to very high housing deficits. The present research project, which started in 2013, aimed to build a rural housing prototype integrating digital manufacturing processes This process comprises different stages and principles, which have been modified and refined through iterations. One of the main objectives of the process is to allow variations, from the definition and integration of dynamic parameters, which can be adjusted according to specific conditions, generating different options in the final result (Duarte 2001). In this context, four design principles were used as the theoretical framework for the integrated design process of the rural housing prototype. It is argued that the elements and prefabricated systems are the primary strategies, to guarantee quality, precision, control in the execution, stability and habitability of the house (Ulrich 2012)
