Subscribers only
Harnessing biomimetic principles, this residence employs a rainwater harvesting system alongside hollowcore walls and sustainable materials to effectively address the challenges of living in a humid climate.
5 key facts about this project
01
Employs a rainwater harvesting system inspired by biomimicry for efficient water collection.
02
Integrates hollowcore walls for enhanced thermal performance and resource efficiency.
03
Features sloped roofs equipped with photovoltaic panels for optimized solar energy capture.
04
Utilizes charred wooden shingles for improved durability and fire resistance.
05
Designed with narrow corridors that provide shade and reduce heat exposure.

### Project Overview
The House of the Future is a residential design situated in a hot and humid climate, aiming to promote sustainable development and modern living practices. The intent is to create a home where energy efficiency and environmental considerations are paramount, while still providing a unique aesthetic grounded in natural elements. The architectural approach emphasizes advanced construction techniques and innovative solutions for water management.

### Spatial Configuration and Innovative Systems
The design thoughtfully responds to climatic challenges by integrating features inspired by natural forms, such as sand dunes and biological water-harvesting strategies. Variations in roof slopes not only enhance aesthetics but also improve ventilation and diffuse natural light within the interior spaces. Specific strategies include:

- **Sustainable Energy Solutions**: The slanted roofs incorporate photovoltaic panels for solar energy generation and include solar water heating systems to further enhance efficiency.

- **Water Harvesting Technology**: A sophisticated rainwater collection system, inspired by the water-conserving mechanisms of the darkling beetle, aims to gather between 0.5 to 3 liters of water daily, significantly reducing reliance on municipal water supply.

### Materiality and Cultural Context
Construction materials have been selected for their durability, thermal performance, and visual appeal. Core materials include concrete for structural integrity, glass for natural illumination while maintaining security, steel for support frameworks, and wood for aesthetic warmth in communal areas. Non-toxic finishes are employed to contribute to the project's sustainability ethos. The design also embraces cultural influences, reflecting aspects of traditional Damascus architecture, adapted to meet the needs of contemporary residents while honoring historic precedents.

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.
