A responsive massing strategy enhances the integration of vertical gardens and a continuous circulation ribbon, creating a mixed-use cultural hub that revitalizes urban interaction in Frankfurt.
5 key facts about this project
01
Responsive massing scales down to blend with surrounding buildings.
02
Continuous circulation ribbon enhances pedestrian movement throughout the structure.
03
Vertical gardens are integrated to promote biodiversity and environmental interaction.
04
Grid-spreading algorithm creates unique voids for natural light and ventilation.
05
Facade features a pixelated design that reflects dynamic structural forces.

The Datum is located in Frankfurt, Germany, close to the Central Station and the Main River. It features a parametric skyscraper designed to emphasize human scale in an urban context. The project integrates public, residential, and commercial spaces, encouraging interaction among users. A continuous circulation ribbon runs through the building, facilitating movement and creating a vibrant urban hub that revitalizes the surrounding area.

Concept and Design Intent

The goal of The Datum is to promote a flow of circulation that connects various public and private areas. This approach establishes a Vertical City framework, allowing the skyscraper to function as a cultural hub while fitting into the broader urban landscape. By prioritizing accessibility and movement, the design engages with the community and adapts to the needs of those who experience it.

Massing and Form

A notable aspect of The Datum is its responsive massing strategy. The shape of the building emerges from dividing the boundary box into distinct public and private zones. The masses are scaled down to match the proportions of nearby structures, ensuring that the high-rise blends into its surroundings. This thoughtful approach makes the building approachable and relevant to the existing architectural context.

Circulation and Green Spaces

The circulation ribbon is key to guiding visitors throughout the space. This feature intertwines with landscaped gardens, enhancing the overall look of the skyscraper. The gardens serve as essential green spaces for pedestrians, encouraging a sense of livability. They provide an opportunity for people to interact with nature while navigating the urban environment.

Facade and Structural Dynamics

Grid-spreading algorithms inform the organization of the building's components and create voids between the masses. These voids help maximize natural light and ventilation, benefiting both commercial and residential areas. A point-attractor method shapes the facade, resulting in a pixelated appearance that reflects the dynamics and forces that influence the design of the structure.

These design elements work together to create a complex relationship among different areas of The Datum. This layered experience invites exploration and enriches the urban life surrounding the skyscraper, highlighting the importance of thoughtful design in high-rise environments.

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.
