Establishing limits for building on beach borders is important in urban intervention projects, since they separate private domain from public life. Contention walls play a crucial role by limiting the area used for building, and also by minimizing the effects of erosion and flooding in urban areas. This article analyzes case studies carried out in Praia do Amor, Outeiro island, in the Metropolitan Region of Belém, and Marudá Beach, a town in the Northeast of the state of Pará, Brazil. Based on the analysis of existing buildings in those locations, this study suggests a set of guidelines for establishing built limits on beaches. This article also provides references for additional studies required.
