Perspectives on sustainable housing development
• Different dimensions of sustainability are implicit within the interests of
different stakeholders, however each one is limited by its own role and
frame of action (budget, land, economic viability, affordability capacity)
• Current barriers to overcome (speculation, urban structure, uncertainty
in development costs.
• Opportunities for municipal housing projects (cultural shift, increasing
costs in mobility, associations between land owners and private
investment, normative and management tools)

Perspectives on collaborative planning approaches
• Opportunities: Chance to overcome barriers for development (less risk
in investment), scenario for local economic development (LED), address
users preferences, lead towards sustainable development.
• Barriers: incompatible interests, political stress, personal limitations, lack
of trust (transparency and economic)

Conclusions
Advantage of having a more comprehensive understanding of the barriers to befaced and opportunities when planning toward sustainable housing development inthe inner city.
A multi-dimensional collaborative approach to assess sites for municipal housingcould stimulate fruitful discussions in planning for sustainable development
Different methodologies and the use of a Planning Support System offer aneffective and transparent approach to better inform the planning process in multistakeholder’s environments.
Use of 3D models (communicative tools) and means to share and exploreinformation by stakeholders facilitated the process of knowledge building and.
Emphasis in using available geographic information. Collaborative planningenforce commitment towards the planning task and to information and datasharing.
