05
Each unit features flexible layouts to adapt to different household needs.

The vertical duplex housing system is set in Bestwood, a location with a rich mining history. The design addresses current housing needs by making efficient use of land. With two separate yet connected residential units, it balances higher density living with the comfort of quality spaces, meeting the demands of modern urban life.

Design Concept

The main idea is to optimize living space in a compact design. This vertical layout allows for flexibility, accommodating different household styles and sizes. By conserving land, the building contributes to a sustainable approach to housing. This design method not only enhances the number of homes available but also nurtures a vibrant community.

Circulation and Connectivity

Two spiraling staircases play a vital role in the overall design. They connect the units while ensuring each retains its own space. Inspired by the shape of a caduceus, these staircases create an inviting flow throughout the building. This feature encourages interaction among residents while still allowing for privacy, responding to the need for both communal areas and personal retreats.

Façade and Aesthetics

The symmetrical façades are designed to face either the street or gardens, enhancing the visual appeal of the building. This design choice ensures a pleasing interaction with the surrounding environment, providing residents with different views and experiences. The architecture reflects themes of contemporary design while acknowledging the historical significance of the area, creating a bridge between past and present.

Spatial Dynamics

The design effectively combines common and private spaces, allowing for meaningful social engagement among residents. Common areas are deliberately placed to encourage interaction, while private quarters offer a sense of security and isolation. This structure promotes a sense of community without sacrificing individual comfort.

Strategically placed windows bring in natural light and frame views of the outside world. This thoughtful detail enriches the living environment, connecting residents with the local landscape while providing a sense of openness and tranquility within the homes.

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.
