The design incorporates sinusoidal towers and an exoskeleton structure to optimize natural light and connectivity, creating a versatile space for office functions in a dense urban setting.
5 key facts about this project
01
Sinusoidal tower design enhances natural light distribution throughout the building.
02
Exoskeleton structure minimizes the need for traditional shear walls, optimizing interior space.
03
Local stair access connects offices to corridor loops every fifth floor, promoting fluid movement.
04
Vertiports are integrated for efficient aerial parcel delivery, streamlining logistics.
05
Landscaped outdoor areas foster a connection between indoor and urban environments.

The Unblock, located in downtown Chicago, focuses on enhancing the relationship between people and their urban surroundings. It serves multiple functions while aiming to create a welcoming environment. The design aims to integrate nature into everyday life, addressing the challenges of living in high-density areas. The key concept features sinusoidal towers that encourage natural light and open space, weaving together a cohesive experience for users.

Innovative Form and Spatial Configuration

The design of The Unblock includes a series of sinusoidal towers. This arrangement merges aesthetic appeal with necessary structural support. The wave-like shape allows light to filter deeply into the building, providing great views while reducing the usual feelings of confinement found in high-rises. This thoughtful approach makes the space feel more inviting and accessible, contrasting the typical look of urban towers.

Interior Layout and User Engagement

Inside, the arrangement emphasizes user interaction with column-free office spaces. These offices can be adjusted to suit different needs and sizes. Each office is linked to a set of stairs that connect to corridor loops every fifth floor. This layout promotes easy movement and communication across the building. It caters to various working styles, encouraging collaboration and productivity among users.

Structural Innovation and Technology Integration

The building features an exoskeleton structural system designed to handle both vertical and lateral forces. This choice minimizes reliance on traditional shear walls, leading to a more flexible use of space. The exoskeleton also influences the building's overall look, showing how stability and design can go hand in hand. Vertiports are part of the technology setup, enabling aerial parcel delivery and smooth logistics access, seamlessly connecting the building to its urban context.

Final Design Detail

Landscaped outdoor areas open to the outside, creating a connection between different environments. These spaces invite natural elements into the building and encourage users to engage with the urban landscape surrounding them. This blend of indoor and outdoor realms reflects a dedication to sustainability and enhances the overall experience for everyone who uses the space.

The Next House: USA — A Global Call to Reimagine the American Suburb

`
Competition organisers

Buildner is launching The Next House: USA, a global architecture competition that challenges architects, designers, and thinkers to reimagine the American suburban home for the 21st century. For decades, the suburban house has symbolized comfort and stability, but today it often reflects excess, isolation, and environmental strain. This competition asks: how can the American home evolve to address climate urgency, economic pressures, and shifting social values?

Participants are tasked with designing a prototype home of no more than 1,500 sq ft (≈140 m²) for a household of two adults and one child. The design should be compact yet generous, adaptable, sustainable, affordable, and replicable across diverse U.S. contexts. More than a design exercise, the competition aims to spark a conversation about how homes can support healthier, smarter, and more connected communities.

The total prize fund is $20,000 USD. The final registration deadline is May 20, 2026, and winners will be announced on September 22, 2026. The Next House: USA invites architects, students, and visionaries worldwide to redefine what the American home means today—and what it should mean tomorrow.
