Suspended housing units provide unique residential opportunities above green spaces, integrating nature with community-focused living along a revitalized railway in Berlin.
5 key facts about this project
01
Suspended housing units utilize innovative designs to maximize views and accessibility.
02
Shared communal spaces include a flexible kitchen to enhance resident interactions.
03
Natural elements are preserved along the railway to create tranquil green zones.
04
Adaptable unit layouts allow for personal modifications to suit diverse lifestyles.
05
Public and private spaces are distinctly separated to promote community and privacy.

The Siemensbahn project in Berlin aims to convert an old railway line into a lively area that combines homes and public spaces. Located in Siemensstadt, the design focuses on adaptability and community involvement. The overarching idea is to blend housing, communal areas, and nature, providing a thoughtful approach to urban living.

Community Integration

The design emphasizes building connections among residents by utilizing the space around the old railway stations. Shared areas on the platforms encourage people to interact and create a sense of belonging. Social spaces enhance the existing urban environment, inviting lively activities and public engagement.

Natural Elements

Between the stations, the project embraces nature, allowing green spaces to flourish. This approach respects the local environment by preserving trees and other plants that have grown along the tracks. These natural areas create calm spaces that contrast with the surrounding urban setting, providing residents with opportunities for relaxation and reflection.

Adaptable Housing Units

A key feature is the adaptable housing units that cater to the diverse needs of residents. Each unit has enough space for sleeping and an adaptable area that can serve multiple functions. This flexibility allows the units to grow or shrink according to what residents need. A larger shared unit with a communal kitchen encourages gatherings, fostering community ties and social interaction.

Public and Private Spaces

The layout of the project clearly separates public areas from private ones. One side of the railway remains open for public use, while the other side provides a more private retreat for residents. This careful planning allows for a comfortable balance between community life and personal space.

A notable aspect of the design is the use of the Spree bridge, where housing units are suspended alongside it. This arrangement maximizes views and accessibility while retaining the bridge's function as a key public space. The design illustrates how old infrastructure can be rethought to meet new needs, contributing to a practical and engaging environment.

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.
