Elevated above the cityscape, modular units constructed with Cross Laminated Timber create a new form of community living that integrates greenery and pedestrian connectivity in downtown London.
5 key facts about this project
01
Modular units are positioned on existing rooftops to optimize space in downtown London.
02
Cross Laminated Timber is used for structural efficiency and sustainability.
03
Greenery is integrated at multiple levels, enhancing livability and aesthetics.
04
Pedestrian pathways connect residential units, promoting community interaction.
05
Bridges link different living spaces, creating a cohesive residential environment.

The Skyline project addresses the urgent need for affordable housing in downtown London. It is set against the backdrop of a busy urban landscape where space is limited and demand is high. The design integrates residential units with existing commercial buildings, creating a community atmosphere. By utilizing rooftops of these structures, it maximizes space while adding to the urban environment.

Architecture Concept

The design incorporates modular frame structures placed on top of existing buildings. This method reduces the visual weight of new constructions while making effective use of land. Each residential unit is carefully designed to blend with the character of the surrounding area, ensuring that the new additions fit well within the existing architectural context.

Land Use Distribution

The layout clearly divides the area into several sections: residential, non-employment zones, green spaces, and commercial areas. This organization helps to meet various community needs. The project emphasizes walkability with pedestrian paths that connect different spaces, encouraging social interaction among residents.

Sustainability and Connectivity

Bridges link the residential units, facilitating movement between them and promoting a sense of community. Greenery is incorporated at various levels, including rooftops and shared areas. This not only adds beauty but also supports environmental goals.

The design features Cross Laminated Timber (CLT) as a primary material, chosen for its effectiveness and sustainability. The use of CLT aligns with the aim of making construction more efficient while reducing environmental impact.

Through these thoughtful choices, the Skyline project meets the need for affordable housing while contributing positively to the urban experience in London. The design fosters a living environment that reflects the needs and aspirations of modern city life.

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.
