Public spaces remain some of the most dynamic sites for unbuilt architectural experimentation, revealing how cities and architects can imagine accessibility, gathering, and civic identity. In this curated Unbuilt edition, submitted by the ArchDaily community, the selected proposals examine parks, pedestrian corridors, cultural landscapes, and open-access urban environments that invite people to meet, move, rest, and participate in collective life. Rather than treating public space as leftover terrain, these projects position it as essential infrastructure—shaping urban health, memory, and social interaction.

BIG – Bjarke Ingels Group has been selected as the winner of the international competition to design the new Hamburg State Opera, a major cultural project planned for the Baakenhöft peninsula in HafenCity, Hamburg, Germany. The building will consolidate the city's opera and ballet companies under one roof, introducing new performance spaces, production facilities, and public amenities along the Elbe. The project replaces the mid-20th-century opera house on Dammtorstraße, responding to the city's call for a venue that reflects contemporary standards in acoustics, stagecraft, and audience experience.
Spaces of hospitality are a mirror to how different cultures articulate generosity, care, belonging, and identity. In busy city settings, this is reflected in hotels, service systems, and curated amenities that directly shape the visitor experience. These spaces translate care into measurable forms, where success is correlated with efficiency, luxury, and brand identity.
The City of Copenhagen has announced Team SLA as the winner of a design competition to create a new, large-scale urban park in Nordhavn. The project, titled "Nordør – New Park", was designed by Team SLA and By & Havn, and envisions a 30-hectare (75-acre) coastal nature park. Led by the design studio SLA, Team SLA includes VITA Engineers, Urban Agency, Aaen Engineering, Pihlmann Architects, Buro Happold, Kerstin Bergendal, Holdbart, and Aiming Spaces.
A "nature park" is a protected area where conservation is balanced with sustainable development and human use. It often encompasses human-shaped cultural landscapes and integrates strategies for regional development, supporting local communities and promoting the conscious use of the land. This framework allows the proposal to be understood as a platform for recreation, eco-tourism, environmental education, research, and regional growth.
A globally-recognized advocate for ecological urbanism, Yu gained international relevance after his "sponge city" philosophy was adopted as a national policy in China in 2013. The approach prioritizes nature-based solutions, such as wetlands, parks, and permeable pavements, to absorb and retain water. This novel method stood in stark contrast to traditional concrete infrastructure, offering cities a way to combat urban flooding and accelerate climate change by working with nature rather than against it. His ideas have since been implemented in hundreds of cities worldwide.
Transcending their role as mere infrastructure, bridges have long served as powerful architectural statements. This expressive potential is now being explored with renewed vigor across South-East Asia, where a growing number of architects are re-evaluating traditional materials. By championing wood and bamboo, these designers are creating distinctive structures that integrate local craftsmanship with contemporary needs, resulting in landmarks that are both functional and deeply rooted in their landscape.
In contemporary architecture, hotel design is no longer defined solely by luxury and accommodation. Instead, it is becoming a platform to explore questions of identity, ecology, and cultural meaning. Beyond providing rooms and amenities, hotels today aim to create immersive experiences that connect travelers to local traditions, landscapes, and communities. In this curated selection of unbuilt hospitality projects, submitted by the ArchDaily community, speculative and competition-winning proposals offer a glimpse into the future of hospitality, where sustainability and storytelling are as central as comfort and style.
Renzo Piano Building Workshop, in collaboration with Betaplan Architects (Athens) and landscape architect Camille Muller (Paris), has revealed the first images of a new cultural center under development in Piraeus, the port of Athens. Commissioned by The Dinos and Lia Martinos Foundation (DLMF), the project seeks to establish an international hub connected to similar art centers abroad, open to the local community, students, and visitors, and contributing to the urban and cultural fabric of the Athens metropolitan area. The complex, called KYKLOS, is planned to host contemporary art collections and cultural programming with an international outlook. Initiated in 2023, the project is currently in development, with construction planned to extend through the last quarter of 2028.
Patio houses embody one of the most enduring architectural typologies, encapsulating the duality of openness and seclusion while nurturing a profound connection with nature. While the term is also used in contemporary American real estate to describe low-maintenance, single-story dwellings on small lots, its classic architectural meaning refers to an introverted design organized around a private, central courtyard. It is this traditional form, the subject of this article, that traces its origins back thousands of years. Patio houses emerged independently in various regions, responding universally to fundamental human needs: privacy, climatic adaptability, and spatial coherence. Despite diverse geographic and cultural expressions, the core principles of introversion, controlled openness, and environmental sensitivity remain remarkably consistent throughout the evolution of this typology.
Across diverse climates and landscapes, architects are reimagining the home as a place deeply rooted in its surroundings, where architecture and environment work together to nurture well-being. This curated selection of unbuilt residences, submitted by the ArchDaily community, are conceived as sanctuaries, offering respite from the pace of urban life and drawing on the restorative qualities of greenery, water, and open air. Nature is utilized as an active presence, shaping courtyards, guiding circulation, and influencing the choice of materials and colors.
At a time of ecological collapse and rising food insecurity, architecture is increasingly called upon to engage not only with landscapes but with the systems that sustain and regenerate them. Among these systems, agriculture occupies a paradoxical role, as both a leading contributor to environmental degradation and a potential agent of ecological recovery. Industrial farming has depleted soils, fragmented habitats, and driven climate change through monocultures, fossil-fuel dependency, and territorial standardization. In response, agroecology has emerged as a counter-practice rooted in biodiversity, local knowledge, and the cyclical rhythms of nature. It reframes farming not as extraction, but as regeneration of ecosystems, communities, and the soil itself.
This reframing opens space for architecture to contribute meaningfully. To align with agroecology is not only to support food production, but to engage with the broader cultural, spatial, and ecological conditions that sustain it. It implies designing with seasonal variation, supporting shared use, and building in ways that respect both the land and those who work it. Architecture becomes more than enclosure — it becomes a mediator of cultivation, reciprocity, and coexistence.

The concrete canyon of Melbourne's Degraves Street was once a stark service corridor in functional obscurity. Today, the narrow laneway now pulses with life beyond its famous café. Native grasses cascade from carefully positioned planters while small shrubs create cooling microclimates. Challenging traditional ecological design models, community-led approaches to biodiversity invite a reimagining of how architects, planners, and communities collaborate to develop biodiverse urban futures.
From forest-inspired offices in Sweden to jungle-nest clubhouses in Tulum, mixed-use architecture continues to evolve as a tool for integrated living. As cities grow and our expectations of public, private, and commercial space shift, designers are increasingly rethinking how different functions including work, play, rest, learning, can coexist in a single architectural language. These projects suggest that buildings and projects no longer need to silo activities, but rather choreograph them to reflect the rhythms of everyday life.
This collection, submitted by the ArchDaily community, presents a global spectrum of approaches to mixed-use design, from large-scale masterplans to conceptual theses. What ties them together is a commitment to spatial overlap, ecological sensitivity, and reimagined programs that prioritize user experience. Whether it's a student dormitory in Tehran, a public plaza in Cairo, or a community hub in Texas, each project embraces complexity to create spaces that are alive with interaction, transformation, and meaning.
Seeking to create a fluid dialogue between architecture and its surrounding landscape, the study of topography embodies an awareness and exploration of the use of materials, self-sufficient strategies, low-maintenance solutions, and landscape designs that integrate into the natural environment and minimize the environmental impact of projects. Beyond recording variations in elevation, sun orientation, prevailing winds, or drainage slopes of the terrain, several architects in Argentina demonstrate a strong interest in developing architectural solutions capable of adapting to natural geographies and restoring the bond between nature and the human being.
BIG, artist Doug Aitken Workshop, NIRAS, Volcano, and RWDI have won a competition to redesign three public spaces surrounding major music venues in Ørestad, Copenhagen.
