Cities can and should be an open field to sustainable circular guidelines since its scale complexity becomes an impact (positive or negative) over the environment as deep as its dimension. On this scenario, construction industry aims to develop products that fulfil also functional requirements and at the same time safety and durability during all the life cycle phases, promoting reversible buildings to avoid constructions obsolescence and recourses{\textquoteright} waste. Most of the Building Sustainability Assessment methods require detail in the input data, hampering their usability at early design stages. So, the paper presents two complementary methods that are being developed to promote early stage sustainability through both sustainability design decision-making guidance and assessment of investment willingness and affordability. The first method enables project teams to compare design alternatives and verify which is the most sustainable choice and alerts them how sustainability concerns are linked to all design criteria, constraints and decisions. The second method is a cost-benefit analysis method to analyse and compare building solutions that consider the stakeholders{\textquoteright} investment willingness and market availability. These new approaches can lead to a more sustainable built environment and contribute to more circular economy since it allows thinking on reversible and transformable buildings since the early design stages choosing solutions closer to the building stakeholders{\textquoteright} investment willingness and the users{\textquoteright} affordability.
