### Overview

The Microhome Whale House, located in Costa Rica, exemplifies modern architecture's integration with the natural environment. Designed to facilitate a profound connection with its surroundings, this compact dwelling prioritizes functionality and comfort while respecting the local ecosystem. The architectural form draws inspiration from the shape of a whale, featuring a curved roof that evokes the dorsal fin, fostering a visual relationship with the lush landscape.

### Material Selection

The construction of the Whale House employs a curated selection of materials that balance durability and ecological considerations. Reinforced concrete serves as the structural backbone, allowing for organic forms while ensuring integrity. Large glass panels contribute to transparency, providing unobstructed views of the surrounding jungle. The interior features sustainably sourced wood, likely cedar or teak, which adds warmth and aligns with environmental principles. Eco-friendly coatings enhance the longevity of these materials, while a hydro energy pump harnesses local water resources to support energy needs and provide potable water.

### Spatial Configuration

Occupying a modest footprint of 24 square meters, the Whale House is meticulously planned to optimize space and functionality. An open-concept living room and kitchen area facilitate social interactions while incorporating flexible furniture solutions, such as folding elements that maximize useable space. The bathroom is efficiently designed with water-saving fixtures, and innovative features like a staircase closet provide additional storage without compromising spatial integrity. The adaptability of the layout ensures a versatile living environment capable of accommodating changing user needs.

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.
