Agustina Iñiguez — Thu, 18 Jun 2026 01:30:00 +0000

Building roofs are advancing through a multidimensional optimization process that encompasses technological innovations, new materials, energy-saving performance, and faster construction methods. From green roofs and rainwater harvesting systems to solar panels, contemporary architects are working to balance aesthetics, performance, durability, and environmental impact in their projects. Roof renovation not only extends the service life of buildings but also reflects an environmental commitment by improving efficiency and sustainability.

Heat as a Design Partner: Trees, Soil, and Wind Corridors as Cooling Infrastructure

"By 2050, almost every child in the world — nearly 2.2 billion children — will be exposed to frequent heat waves." UNICEF's warning is often read as a public health forecast, but it is also a challenge to architecture and the way cities are built. As extreme heat intensifies across Asia, Europe, and beyond, thermal comfort should not be reduced to merely an indoor service delivered by machines. Air-conditioning has become a life-support system for many cities, especially in dense, humid, and rapidly urbanizing regions. Yet to rely on it as the default answer is to treat heat as something that can simply be moved elsewhere (and in the process generating extra heat) — expelled from interiors into streets, service alleys, energy grids, and the atmosphere. Its expansion increases energy demand, produces waste heat, and reinforces unequal access to comfort.

How Architecture Is Learning to Generate Its Own Energy

Agustina Iñiguez — Wed, 11 Mar 2026 01:30:00 +0000

Beyond being a source of life, the power of the sun in architecture has long been tied to humanity's need to harness and control it as a vital resource. Since ancient times, solar energy has been used to measure time, support planting and harvesting, and provide protection from heat and cold. Today, solar radiation plays a significant role in global energy consumption. Architectural solutions based on materials, technologies, and environmental analysis are developed with an understanding of solar energy's capacity to transform the interior environment of buildings. But how can buildings be transformed into sources of clean energy?

Heat Resilient Design: How City Leaders Use Building Materials to Fight Urban Heat

Olivia Poston — Tue, 17 Jun 2025 05:00:00 +0000

Extreme heat is one of climate change's most urgent and rapidly growing consequences, especially in cities. Urban areas are particularly vulnerable because they trap heat in building materials and urban streets, creating dangerous conditions for residents. As temperatures continue to rise and heat waves lengthen, cities are grappling with how to remain livable in the face of this intensifying threat.

How to Design Residential Urban Terraces: Strategies for Living Well in High Places

Camilla Ghisleni — Wed, 21 May 2025 07:30:00 +0000

In today’s dense, vertical cities, terraces—often overlooked as mere technical rooftops—are emerging as key spaces for reconnecting with nature, expanding residential functions, and offering moments of collective relief. Particularly in single-family homes located in compact urban areas, these elevated surfaces represent valuable opportunities to increase usable living space without occupying more land. By lifting daily life above street level, terraces open new ways of inhabiting the city, enabling a range of uses from leisure and contemplation to food production and social gathering. In contexts marked by limited green space and strained infrastructure, they hold the potential to generate what landscape architect Catherine Mosbach calls "additional layers of urbanity." Whether imagined as hanging gardens, gathering spots, edible landscapes, or wellness zones, terraces challenge the idea that the city ends at the top floor—inviting us to see the roof as a new kind of ground.

A Skyward Shift: Exploring the Social Impact of Elevated Public Spaces in Cities

Jonathan Yeung — Mon, 16 Sep 2024 04:00:00 +0000

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.

How Are Super Tall Buildings Aging?

In 1853, at the New York World Expo, a man climbed onto a suspended platform and ordered the rope supporting it to be cut. He dropped a few inches, but the safety system activated, and the platform remained stable, to the delight of the watching crowd. At that moment, perhaps not even Elisha Graves Otis realized how his invention would permanently change the course of architecture.

Modular, Photovoltaic, Green or Blue Roofs: How to Choose the Best Waterproofing System?

Eduardo Souza — Mon, 22 Apr 2024 01:30:00 +0000

Among the "Five Points of New Architecture" formulated by Le Corbusier, terrace gardens figure as a way to take advantage of a building's so-called fifth facade, either as leisure areas or landscaping spaces. Thanks to technological advances in reinforced concrete in the mid-twentieth century, usable flat roofs are far from new. There are traces in Mesopotamia and vernacular architecture from Greek and Arab civilizations. However, problems that frequently arise relate to infiltration and leaks. Water is relentless in finding a place to drain, and flat roofs are exposed to this when execution and design are not carefully thought-out. In fact, as documented in several letters, this was a source of disagreement between the owner and the Swiss-French architect in the case of the influential Villa Savoye. Today, nonetheless, there are good waterproofing options on the market that provide durability, resilience, adaptability and, above all, avoid headaches and fights between builders and owners. Elevate is built on 40 years of history in the production of roofing membranes, as well as insulation and vapor barriers, and develops solutions for waterproofing flat roofs with a low inclination.

The Right to the Slab: Social Life and Alternative Ways of Conceiving Space

Helena Tourinho — Tue, 06 Feb 2024 05:00:00 +0000

As architectural theory undergoes a process of review and updating, there is a rejection of prevailing binary distinctions found both in common perception and in architectural education. Traditional dichotomies such as center versus periphery, the 'formal' versus 'informal' city, and design as a rigid technique versus construction as improvisation have been persistent architectural themes, with a history of ongoing debates. Despite the dominance of global northern perspectives on what constitutes good architecture or how it should be approached, reality consistently reveals itself to be more intricate, diverse, and multidimensional.

The Legacy of the Sawtooth Roof, an Icon of Industrial Architecture

James Wormald — Wed, 17 Jan 2024 04:00:00 +0000

A historic symbol of the industrial age, the sawtooth roof is a lasting legacy of architectural history. Although a functional invention born from necessity nearly 200 years ago, the iconic shape is enjoying a renaissance in many contemporary projects.

Natural Roofs: Sustainable Alternatives for Modern Buildings

ArchDaily Team — Wed, 20 Sep 2023 05:00:00 +0000

Nowadays, when we imagine enclosed spaces, concrete slab roofs often come to mind. However, the use of concrete in construction now raises concerns due to its documented contributions to climate change and environmental harm. In response, it is necessary to incorporate vernacular and traditional techniques into our architectural toolkit. In this context, natural coverings emerge as an excellent solution. Despite their alignment with numerous desirable project attributes, these materials, which have sheltered humans for centuries, are still underutilized in contemporary construction. Natural roofs offer biodegradable materials, making them a more sustainable option with an aesthetic appeal and enhanced thermal comfort.

Brazilian Houses With Useful Slabs

The tradition of modern architecture confirms that building roofs are usable spaces as significant as indoor areas. After all, the garden terrace is one of the five points of new architecture, according to Le Corbusier. Although he popularized the concept, the use of rooftops dates back even earlier, encompassing various roles across time, from lookouts for ancestral astronomical studies to more contemporary cultivation areas, passing through the bureaucratic accommodation of electrical and sanitary installations. By offering open space and direct sky access, building roofs have evolved. In dense urban landscapes, converting this space into a leisure area is a logical choice.

What to Consider When Choosing Roofing Materials?

Helena Tourinho — Thu, 06 Jul 2023 05:00:00 +0000

There are many ways to define architecture, from the most technical to the most poetic. It uses many aspects within its context: space, program, tectonics, and gesture, which refers to the stroke, the drawing, and the design. Perhaps the quick sketch that comes to mind when talking about gesture is that of shelter: a cut or elevation, with human scale, of vertical enclosures and coverings.

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.

The Threshold Between Daylight and Architecture: Flat Roof Access Hatches

Enrique Tovar — Mon, 20 Mar 2023 01:30:00 +0000

Beyond light as a physical phenomenon perceptible by the human eye, daylight is an inexhaustible architectural resource that is sometimes taken for granted. Just like the air we breathe, we are all aware of the existence of light, but rarely do we seek to do anything else with it. It is essential to recognize its presence as an enabler of experiences in space, due to its intrinsic relationship with architecture and human beings.

13 Houses with Pitched Roofs and their Sections

The roof is one of the most essential structural elements of nearly every construction. It is the element that allows a delineated space to transform into one that feels protected. Strongly related to the climatic conditions of the context, the roof's variations in aesthetic and structural design have allowed architects to indulge their stylistic preoccupations to convert roofs not only into elements of closure and climate protection but into a character-giving feature that lends identity and flair – especially when the roof becomes a wall.

The History of Useful Flat Roofs

Giovana Martino — Mon, 05 Dec 2022 05:00:00 +0000

For some time now, roofs have become leisure spaces, whether in large luxurious buildings or houses on the outskirts. This condition, however, is not limited to our times. Different cultures at different times used flat roofs in their architecture, in different ways.

MVRDV, Superworld, and the City of Rotterdam Create Software for Reimagining Rooftops

"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.
