As cities continue to expand upward, the office tower remains one of the most visible symbols of architectural ambition and urban evolution. No longer defined solely by efficiency or corporate image, contemporary workplace architecture is being reimagined as a hybrid ecosystem, one that balances density with daylight, productivity with well-being, and technology with material and spatial integrity. The following unbuilt projects, submitted by the ArchDaily community, reveal how architects across continents are rethinking the typology of the tower, turning verticality into an opportunity for connection, adaptability, and sustainability.
From India's Shivalik Curv and Embassy Zenith, where form and movement are combined to redefine skyline identity, to Dungen in Sweden, a low-rise timber office that mirrors the calm of a forest grove, each project explores how workplaces can become more flexible, humane, and environmentally conscious. In Kyiv, APEX Business Center positions itself as a catalyst for urban vitality, while Jakarta's BNI Tower PIK 2 transforms the corporate tower into a crystalline symbol of growth. In Munich and Ankara, mixed-use concepts like Highrise Hufelandmark and Rhythm Ankara explore the office as part of a broader civic landscape, where work, leisure, and public life intersect.
As cities grow and available land becomes more limited, high-rise architecture plays an important role in addressing urban density while shaping new ways of living and working. Tall buildings are evolving beyond their traditional functions to integrate environmental strategies, enhance public engagement, and contribute to the urban fabric. Architects are exploring new materials, energy-efficient technologies, and spatial configurations that make towers more adaptable to their surroundings. Some projects incorporate green spaces and shared amenities to create a stronger connection between the built environment and its users, while others introduce innovative construction techniques to improve sustainability and efficiency.
Among this selection of projects submitted by the ArchDaily community, The Residences at 1428 Brickell by Arquitectonica in Miami, United States introduces a solar-powered facade that contributes to the building's energy needs. In Dubai, UAE, AVA by SOMA creates a transition from the city into a more enclosed, water-defined environment with a focus on luxury living. In Bangkok, Thailand, HAS Design and Research proposes the Bangkok Civic Center Tower as a new type of public space, combining green landscapes with mirrored surfaces to connect the city with nature. These projects reflect different approaches to vertical architecture and highlight how designers are responding to the challenges and opportunities of dense urban environments.
Humanity has become obsessed with breaking its limits, creating new records only to break them again and again. In fact, our cities’ skylines have always been defined by those in power during every period in history. At one point churches left their mark, followed by public institutions and in the last few decades, it's commercial skyscrapers that continue to stretch taller and taller.
The Council on Tall Buildings and Urban Habitat (CTBUH) has developed its own system for classifying tall buildings, stating that the Burj Khalifa (828 m.) is the world’s tallest building right now. Read on for the 25 tallest buildings in the world today.
Naturally, a higher population density prevents the formation of ghost towns and vacant shops, which can become hotbeds for crime. However, these positive views on dense living environments often rest on optimistic assumptions about urbanism, such as minimal friction among individuals, easily maintained hygiene and a natural formation of diversity.
Zaha Hadid Architects (ZHA) has just begun renovating the iconic Schuylkill Tower in Monaco. Originally built in 1963, the tower currently stands tall as Monaco’s first-ever high-rise. ZHA conducted a feasibility study evaluating its development prospects and the scope of necessary renovations. This led to ZHA’s collaboration with local firm Square Architecte to revitalize and expand the iconic structure, set to be completed in May 2027.
Whether rain or shine, Toronto is a yearlong bustling city, the largest in Canada and the fourth largest in North America. It’s become a cosmopolitan center with its renowned business district and cultural venues/ events that come alive during the summer and early fall nights. Toronto suggests a beautifully diverse urban setting between shimmering high rises and smaller brick houses, intertwining residential and vibrant commercial areas, public parks, and even beaches. All become part of the city's striking skyline, crowned by the iconic CN tower.
Toronto’s ongoing sprawl and constant urban development are noticeable as new projects spread through the city, weaving themselves into the existing buildings, from 19th-century landmarks such as the Gooderham Building to modern and contemporary major works like the Aga Khan Museum. These new constructions include increasing adaptive reuse and retrofitted projects throughout the city as more efforts and incentives are provided to reduce carbon emissions.
The construction of Torres del Parque began in 1968 and was completed in 1970. Between 1964 and the start of the project, there was a period of uncertainty, doubts, and successive trials to find the right form for the project, not only from an architectural perspective but also from urban and landscape points of view.
The site, characterized by its overwhelming topography, the Plaza de Toros, the abandoned Parque de la Independencia (for over 15 years), and the magnificent panoramic view of the foothills, still untouched by the multitude of towers and dense buildings, invasions, and senseless occupations of the area, should not only be taken into account in the development of the project but, above all, be exalted through architecture that is implemented in such a correct and sensitive manner that it transforms and shapes the city. It should be the heartbeat of the place and a meeting point between reason, enchantment, and poetry. Between clarity and magic, an architecture that can be discovered, that doesn't impose itself, as it is more beautiful when discovered with surprise, like discovering nature. Ultimately, an architecture that integrates with the existing Plaza de Toros and allows transparency between the city and its foothills, reclaiming the steep street adjacent to Parque de la Independencia and transforming it into a pedestrian garden formed by stairways and ramps connected to the residential complex and the park.
Milan’s urban fabric has long been defined by change. In a city known for its historic monuments, from the Piazza Duomo and Milan Cathedral to works like Velasca Tower, contemporary architecture must balance many existing contexts. Emerging as a global center for design and culture, Milan has become home to new buildings and structures addressing this condition as iconic landmarks and expressive forms. Actively building upon its legacy, Milan has turned its attention to the sky.
