# Analytical Report on the "Guest House Volcano" Architectural Design Project

## Overview

Located in a sensitive ecological area potentially characterized by volcanic terrain, the Guest House Volcano is designed as a modern accommodation facility that emphasizes sustainability and adaptability. Influenced by Iceland's geological features, the project creates a clear relationship between human habitation and the surrounding natural environment.

## Spatial Organization and User Experience

The site plan adopts a radial arrangement centered around a prominent main house, facilitating a communal atmosphere. This layout incorporates multiple interconnected modules for distinct functions: the main house serves as a hub for social interaction and dining, while various sleeping modules accommodate diverse group sizes, promoting versatility in guest experiences. The inclusion of corridor modules enhances connectivity between living spaces and communal areas, encouraging interaction and movement.

## Materials and Sustainability Features

The design showcases a deliberate selection of materials aimed at optimizing performance and sustainability. Concrete, chosen for its structural integrity and thermal mass, aids in temperature regulation. Wood is utilized to enhance interior aesthetics and warmth. Porous concrete addresses environmental concerns through potential rainwater management integration. The incorporation of triple-glazed windows maximizes insulation and natural light while green roof systems mitigate runoff and foster biodiversity. Additionally, geothermal heating systems leverage local resources for energy efficiency, and natural ventilation strategies promote air circulation without reliance on mechanical systems.

These elements reflect a commitment to sustainability and resilience, aligning with contemporary environmental standards and addressing the increasing demand for eco-friendly accommodations.

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.
