# Architectural Design Report: Coral House

## Overview

Coral House is located in a region known for its natural coral stone, and the design is rooted in both the ecological context and cultural heritage of the area. The intent of the project is to create a sustainable, adaptable living space that integrates seamlessly with its surroundings while enhancing community engagement. This project represents a forward-thinking approach to modern housing by incorporating traditional materials alongside contemporary construction methods.

## Structural Assembly

The design utilizes a modular framework, facilitating straightforward assembly and flexibility for future modifications. Each unit can be adapted to accommodate the changing needs of residents by allowing for the easy addition or removal of walls. This approach to design not only enhances the longevity of the structures but also supports a lifecycle housing concept that prioritizes long-term usability.

## Spatial Configuration

The interior layout promotes a harmonious balance between communal and private spaces. The configuration features varied room sizes, fostering customization to suit diverse living arrangements such as multi-generational households. Daylight plays a crucial role, with strategically placed windows enhancing natural light penetration and energy efficiency. Moreover, each unit emphasizes connectivity to outdoor spaces with private terraces and gardens that include native flora, encouraging interaction with the natural environment.

## Community Interaction

The project envisages a clustered arrangement of Coral Houses to foster a sense of community while preserving individual privacy. Shared pedestrian pathways and communal gathering areas enhance social interaction among residents, promoting a neighborhood model that supports both personal and communal relationships.

## Upcycling and Sustainability

A commitment to sustainability is reflected in the use of locally sourced materials and innovative recycling practices. The project aims to significantly reduce carbon emissions associated with construction by reusing waste materials, potentially cutting down concrete-related emissions by up to 75%. Additionally, design elements such as sun shading devices and natural ventilation strategies further minimize reliance on mechanical cooling, aligning the project with contemporary ecological standards.

## Aesthetic Considerations

Architecturally, Coral House reflects a modern aesthetic that resonates with local traditions. The facade features textured surfaces inspired by coral stone, providing both visual interest and passive cooling benefits. The integration of ambient and accent lighting enhances the building's character and ensures visibility and security during nighttime.

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.
