The main core structure enables vertical expansion and utility integration, creating adaptable living spaces that foster community engagement and connection.
5 key facts about this project
01
The main core efficiently houses essential utilities to streamline living.
02
The design allows for vertical expansion, accommodating changing family sizes.
03

05
Community integration is prioritized through thoughtful spatial organization.

The Incremental House designed by Jonathan Calle brings forth a modern approach to residential living within a community setting. Located in an urban context, the design focuses on micro homes that can expand over time according to the occupants' needs. The concept emphasizes both personal living spaces and the importance of building connections among residents through thoughtful architectural planning.

Main Core Configuration

At the center of the design lies a main core that contains key serving lines, such as plumbing, electrical, and mechanical systems. This organization separates private areas from public ones while ensuring easy access to essential utilities. It is a functional solution that aims to improve daily life for residents, making navigation within their homes straightforward and efficient.

Phased Development Approach

The design employs a phased development strategy that allows for growth as needed. Each phase demonstrates how additional floors and height can be integrated into the existing structure. This flexible approach makes it possible for families to adapt their living conditions as their needs change, allowing the homes to evolve over time.

Community Integration

An important aspect of the design is its focus on community integration. The layout encourages interconnected living spaces that promote social interaction among residents. By facilitating engagement in shared areas, the Incremental House aims to create a strong sense of community where neighbors can connect and support one another.

Visual Representation and Spatial Dynamics

The project includes various visual elements such as front elevations, sections, and isometric views to illustrate its design intentions clearly. These images show not only individual living units but also how they fit together in a larger community. This approach highlights both personal comfort and the collective experience of living together, reinforcing the cohesive nature of the 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.
