Necessity and investigation are prerequisites for the design of housing: social, environmental, and economic factors affect the architectural investigation of program, technology, and form. Since the publication of Actar\`s first volume on housing, \`Housing + Singular Housing, 2002,\` the continued emergence of architectonic tools has generated significant interaction between construction, surroundings, and inhabitant, while simultaneously addressing the complexities of an ever-changing context, shaped by interests outside of the discipline. The discourse of contemporary housing demands a reassessment of the architect\`s role in the construction of territory, the management of natural resources, the reconfiguration of the city, and the treatment of the necessities of an increasingly diverse and dynamic society.
