The design vision for "Boston 2070" outlines a high-rise office tower located in downtown Boston, addressing the challenges posed by rising sea levels. The project aims to combine practicality with sustainability and enhance urban living. By employing floating architecture, the building rises above potential floodwaters while fostering harmony with the surrounding landscape, thereby redefining the relationship between urban spaces and natural elements.

Floating Architecture

At the core of the design is the concept of floating architecture, which elevates the building about a meter above the ground. This approach helps respond to the effects of climate change, ensuring that the structure remains functional in a city increasingly at risk of flooding. The floating platform acts as both a structural support and a unique aspect of the design, connecting the building to its urban environment.

Garden City Principles

The project emphasizes garden city principles, incorporating vertical green spaces that support both aesthetic appeal and ecological health. These elevated green areas are designed to prevent flooding damage while inviting biodiversity into the built environment. Bird-friendly pathways are part of the design, promoting coexistence among city residents and local wildlife.

Functional Design

The design features various functional spaces, including flexible office areas that can adapt to the changing needs of modern work. The spacious sports areas encourage health and wellness among users, while high-tech retail options reflect current shopping trends. A theater and food court further enhance the community feel, creating spaces for people to gather and interact.

Virtual Integration

As work environments evolve, the design takes into account the growing importance of virtual spaces. It includes areas that facilitate both physical and remote work arrangements, responding effectively to changes in how people engage with their work. This aspect of the design addresses potential vacancies while ensuring that the building remains active and usable.

The tower offers sweeping views of the Boston skyline from various levels, reinforcing the connection between those inside the building and the historic city around it. This integration enriches the experience for users, highlighting both the modern features of the design and the cultural significance of its setting.

Competition organisers

The Buildner’s Unbuilt Award 2025 is an international architecture competition dedicated to recognizing and celebrating the value of unrealized architectural designs. It invites architects, designers, and students worldwide to submit visionary projects that have not yet been constructed, highlighting the power of ideas and the creativity behind the design process. By focusing on unbuilt work, the competition aims to bring forward concepts that shape the future of architecture and push the boundaries of the profession. 

Participants can compete in three categories based on project scale: Small Wonders (up to 100 m²), Medium Marvels (101–999 m²), and Large Visions (over 1,000 m²). Each category winner will receive €20,000, and additional prizes include honorable mentions, student awards, and a special Best Presentation Award. Winning projects will gain significant international exposure through Buildner’s publicity campaign and a feature article on ArchDaily, providing a unique opportunity to showcase creative ideas to a global audience. 

The Buildner’s Unbuilt Award 2025 encourages entrants to submit any type of unbuilt project, from conceptual visions to detailed designs, celebrating bold innovation without the constraints of realization. Important deadlines: registration closes on October 30, 2025; submissions are due by November 20, 2025; winners will be announced on December 17, 2025.
