With sharp angles and a green roof that blend seamlessly into the mountainous landscape, the cabin utilizes sustainable timber and glass to create a compact retreat that fosters a deep connection with nature.
5 key facts about this project
01
Sharp roof angles enhance water runoff and blend with the mountainous terrain.
02
A green roof system promotes biodiversity and aids in rainwater absorption.
03
Floor-to-ceiling windows create unobstructed views of the surrounding landscape.
04
Sustainable materials include charred wood for durability and minimal maintenance.
05
The compact footprint maximizes space efficiency while maintaining functionality.

## Overview

The Acute Cabin is situated along the shores of Lake Doxa in Korinthos, Greece, and serves as a microhome designed to enhance interaction with its surrounding natural environment. The architecture prioritizes a minimal footprint while integrating systems that augment its functionality and ecological harmony within the landscape.

## Spatial Strategy and Design Language

The design incorporates acute angles and geometric forms, reflecting the mountainous silhouettes that characterize the site. This architectural decision fosters a visual relationship with the natural topography while ensuring the structure remains distinctive as a modern interpretation of traditional cabins. Key features include a clear geometric language in the roof pitch and clean lines, contributing to a refined yet organic appearance. Expansive glass elements promote a continuous dialogue between interior and exterior spaces, inviting natural light and framing views of the picturesque surroundings.

## Materiality and Sustainability

Material selection plays a crucial role in the project's sustainability and aesthetic appeal. Structural elements primarily consist of wood, which provides both warmth and natural insulation. Large, floor-to-ceiling glass windows enhance thermal performance with low-emissivity coatings while offering visual access to the lake and hills. Metal roofing materials increase durability and incorporate discreet solar panels, further enhancing energy efficiency. A green roof system not only contributes to insulation but also supports local biodiversity. Composite materials used in furniture provide a blend of organic appeal and modern design, emphasizing the project's commitment to sustainable practices. The structure's distinctive acute roof pitch efficiently channels rainwater, minimizing maintenance requirements and showcasing a practical approach to design.

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.
