Rooftop Architecture: The Latest Architecture and News

With escalating land values in urban centers, there has been a growing trend to float public spaces from ground level to elevated locations, such as rooftops or podiums between buildings. From a development perspective, maximizing floor area has become crucial as urban environments expand. Ground-level spaces are highly sought after for retail use due to their strategic location, which attracts foot traffic and potential customers and drives city development and economics.

This financial consideration, which often guides building activities and directions in urban centers, contradicts design principles advocated during the modernist era for the benefits of better outdoor space for the public, such as the concept of 'Freeing the Ground'. Architects like Le Corbusier championed this concept through projects like Villa Savoye and Unite d' Habitation. These modernist designs envisioned a future where buildings were elevated to restore open, accessible outdoor ground-level spaces for its users. However, for the reasons above, many contemporary projects instead seek to replicate the function of public grounds within the building's structure.

Highlighting an untapped spatial resource, MVRDV's Rooftop Catalogue, in collaboration with Rotterdam Rooftop Days, is now available online for free. Commissioned by the City of Rotterdam, the Rooftop Catalogue presents 130 innovative ideas to make use of Rotterdam's empty flat roofs, showcasing a potential new phase in the city's development and illustrating how reprogramming rooftops can help with issues such as land scarcity and climate change while also addressing the practical side of repurposing these spaces in terms of construction options and suitable sites.

CRA - Carlo Ratti Associati and architect Italo Rota have developed a project to transform an 18^th-century hospital complex in Modena, Italy, into a multidisciplinary cultural and innovation hub. The master plan for the new hub, called AGO Modena Fabbriche Culturali, includes an origami-inspired kinetic roof designed in collaboration with artist-engineer Chuck Hoberman. The feature will cover a triangular-shaped plaza in the center of the complex. The restoration plan also aims to create flexibility so that the structure can easily adapt to changing future configurations.

“Understanding precedes action.” That is the motto of the Urban Observatory, an interactive installation and web app created by TED founder Richard Saul Wurman that compiled a wide range of urban data for over 150 cities, allowing users to compare various characteristics of those cities – from population density to traffic speed limits – side-by-side. Urban Observatory was first created in 2013, a banner year for news about urban big data; later that same year, Waag made headlines with its interactive map visualising the age of every building in the Netherlands. The emergence of such platforms allowed people to see the world around them in new ways.

With the rise of Google Earth and other GIS tools, and platforms like envelope.city, or environmental simulations based on digital twin models of cities, urban big data has quietly come to underpin a wide range of tools used by professionals who shape our cities, with both the amount of data collected and the influence it has over decision-making expanding dramatically. However, these advances typically happen behind closed doors and in undemocratic spaces. How long must we wait for software that has all the user-friendliness, accessibility, and appeal of those older platforms, but which provides the average person with the tools to shape their city? In other words, if “understanding precedes action”, then why after almost a decade are we not seeing big-data-driven apps that encourage the public to actually do something?

Designed by Rotterdam Rooftop Days and MVRDV, the Rotterdam Rooftop Walk has finally opened to the public. The installation offers visitors a new perspective on the city, with a 30-meter-high aerial bridge that spans across a variety of the city’s rooftops, from the roof of The Bijenkorf department store to the top of the World Trade Centre plinth. The project aims to showcase how rooftops can provide an added layer of public infrastructure in a dense city where public space is scarce. Rotterdam Rooftop Walk is open from May 26 to June 24 from 10:00 to 20:00.

Setting the stage for Rotterdam Architecture Month this upcoming June, MVRDV have designed a temporary rooftop platform on the Het Nieuwe Instituut in Rotterdam. The 600-square-meter event space titled The Podium will be elevated 29 meters and covered with a striking pink color, making it visible to all pedestrians on ground level. The installation will open to the public on June 1st, coinciding with the inauguration of the Rotterdam Architecture Month Festival, and will continue to be used for events until August 17th.

MVRDV revealed its design for a temporary intervention that takes tourists and city dwellers on a walk across several rooftops in Rotterdam, highlighting an untapped potential for expanding the public realm. Created in collaboration with Rotterdam Rooftop Days, the project will feature an aerial bridge from the roof of The Bijenkorf department store to the top of the World Trade Centre plinth and will be available to the public from May 26 to June 24 2022, during Rotterdam Architecture Month.

Though seemingly opposite environments, cities are a lot like rainforests. At ground level, the world is dank, dark, and full of predators. Inhabitants seeking fresh air, sunshine, and privacy have only one direction to go: up.

So in the urban jungle, it’s only natural to build a “canopy” in the form of rooftop architecture. The popularity of rooftop amenities across residential, commercial, hospitality, and even health-care projects shows that’s exactly what’s happening.
