Pitched roofs and terraced lots or hillsides are some of the oldest, yet still highly functional, solutions for rainwater dispersal, redirection, and erosion management. While most constructions today still opt for traditional pitched or flat roofs, advancements in construction materials and techniques are leading to greater design exploration and layout variations. This has resulted in a rise in green roofs, passive insulation solutions, and more innovative uses of rooftops. One particular case has been the recurrence of the staircase or terraced roofs that often bring about a smooth continuity with the site and provide additional functional spaces to the project.

Design Collective EUROPARC Unveils the Winning Proposal for the Renewed European Parliament Building
EUROPARC, a pan-European design collective, has been announced as the winners of the international competition to renew the Paul Henri SPAAK Building in Brussels, Belgium. The building housing the Parliament of the European Union has many shortcomings, yet the winners of the competition recognize that demolishing and replacing it might not be a responsible or sustainable solution. The existing building is, therefore, reimagined and adapted better to fit the needs and the identity of the EU. EUROPARC is made up of five architectural studios from five European countries: JDS Architects (DK/BE), Coldefy (FR), CRA-Carlo Ratti Associati (IT), NL Architects (NL), and Ensamble Studio (SP), with the support of engineering companies from UTIL (BE) and Ramboll (DK).
Roof Waterproofing with Water: A Solution by ‘Brasil Arquitetura’
During the modern period, the buildings that used the traditional sloping roofs with tiles, draining the waters as quickly as possible, have begun to give way to the well-known 'waterproof flat roofs.' In spite of delivering a clean aesthetic to the project, allowing the use of the last slab as a space for living and contemplation, this solution can become a headache for its occupants if its execution and design are not careful. It is no accident that there have been infiltrations in famous modern buildings, such as the Vile Savoye or the Farnsworth House, designed by great masters of architecture. Currently, the civil construction industry has developed more sophisticated products and techniques that drastically reduce the chances of subsequent infiltration. However, we could say that waterproof flat slabs continue to be fragile points in buildings. The architects from Brasil Arquitetura have improved an inventive and very simple solution to avoid infiltrations in flat slabs, much used in the 70's by architects like Paulo Mendes da Rocha and Ruy Ohtake, filling them with vegetation.
