During the last two decades, the Brazilian real estate market underwent several changes, first structural, with the adoption of a legal framework that resolved the open questions of the sector, which would in a second moment boost the gains of the sector when favored by an economic conjuncture, both globally and locally. In mid-2014, a market that had been extremely hot since 2007 had already given way to a situation marked by a sharp drop in income levels, increasingly less affordable and more expensive credit, and strong distrust on the part of investors and real estate buyers. The maintenance of the scenario described above - due to factors related to interest, unemployment, political crisis, etc. - culminated in the picture of voluminous stocks and rare launches that can be seen in Rio de Janeiro since then, especially in the West Zone. In order to optimize the slow resumption expected for the market starting in 2018, construction companies and developers are investing in technological innovations aimed at increasing efficiency in some stages of the incorporation projects, such as architecture, engineering and construction (AEC) sales and marketing, legal procedures, etc. However, we do not yet see in the real estate market measures that affect the adherence between what is offered and what the target consumer really wants. In this context, this work aims to explain the preferences of real estate consumers in Barra da Tijuca through the application of the conjoint analysis method. To this end, a focus group was formed with real estate professionals aiming at defining the main attributes of such product and its respective levels. With the main points defined, a fractional factorial project was carried out with fourteen products, which, in turn, were submitted to a consumer survey, in order to reveal their preferences. In the midst of the various analyzes made possible by the research, it was evident that, among the selected attributes, the location was the one that showed greater weight in the consumer decision, followed by the size/typology of the apartment and - contrary to what was initially imagined - the leisure structure was the least important attribute for consumers. In time, it is in the interest of the market that studies like this are made for other growth vectors of the city (such as Campo Grande and Guaratiba) and periodically, since preferences change with the new generations entering the labor market and gaining purchasing power, which clearly occurs among the millennials, a generation born in the mid -1980s and 2000, which is currently not only redefining these preferences but also indicating the future trend of demand.
