## Overview

The Lagom Cabin exemplifies a modern approach to sustainable microhousing, designed to accommodate contemporary living needs while adhering to the Swedish "Lagom" philosophy, which emphasizes moderation and balance. Located in contexts that can benefit from various climatic conditions, the project seeks to minimize its ecological footprint through thoughtful design strategies that prioritize functionality, comfort, and a connection to nature.

## Spatial Configuration and User-Centric Design

The architectural layout features a rectangular prism measuring 27 meters in length and 5 meters in width, optimizing the usability of the living space. Essential areas include a combined living space that serves as both a bedroom and office, a compact kitchen designed for efficient storage and laundry use, and a minimalist bathroom that incorporates the necessary utilities. The design also integrates multipurpose furniture, primarily constructed from plywood, offering flexibility for various activities such as dining, relaxing, and working. Each furniture piece is crafted to allow dual functionality, aligning with the minimalist ethos of the cabin.

## Sustainable Innovations and Material Selection

The project employs a range of sustainable materials and technologies, including Kingston QuadCore panels, birch plywood for internal structures, and double-glazed doors to improve energy efficiency. The cabin is equipped with an off-grid solar energy system utilizing flat flexible solar panels and features a rainwater collection system with a 1100-liter tank, enabling self-sufficiency. Bioclimatic design considerations, such as a sloped roof for optimal water collection and natural ventilation via crossed openings, enhance internal climate control. The careful selection of materials and innovative systems underscores the cabin’s commitment to environmental sustainability while fostering a harmonious living 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.
