A Core Structure Supporting Flexible Living Spaces in an Integrated Community

Project in-detail

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
Incremental phases enable residents to adapt their homes over time.
04
Interconnected living spaces foster social interaction among residents.
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.

Organised by Buildner in partnership with Kingspan and Hapi Homes, this tenth edition sets the challenge of designing a dwelling for two people within a maximum floor area of 25 m², encouraging bold solutions adaptable to any urban or rural location. The competition continues Buildner’s mission to foster innovative approaches to compact, energy-efficient housing that can address pressing global challenges.

This year’s edition offers a generous total prize fund of €100,000, including the Kingspan Award for designs that integrate high-performance Kingspan products and the Hapi Homes Award for a project selected for real-world construction. In addition to cash prizes, the winners gain international exposure through Buildner’s media partnerships, publications, and a dedicated MICROHOME magazine, further amplifying their ideas to the wider architectural community.
