An architecture degree may provide a vast curriculum, but many of the skills needed for a project lie outside the discipline. This is especially true for urban-scale projects. They demand expertise in areas like traffic studies, structural calculations, landscape design, and technical installation forecasting. These are often seen as "complementary" but are, in fact, fundamental to the overall design.

In a country like Portugal, with a relatively small but geographically diverse territory, the challenge of connecting different parts of the territory – whether to cross a river or link one level of a city to another – is a constant one. Its largest metropolitan areas, such as Lisbon and Porto, share a rugged geography of steep valleys and hills. These features led to the development of elevators and funiculars, like the Santa Justa Lift and the Bica Funicular in Lisbon, and the Guindais Funicular in Porto. Today, besides improving urban mobility, they have become tourist landmarks.
