## Overview

The Modular Mountain project, located in the Himalayan region, is conceived as a sustainable accommodation designed to provide trekkers with comfortable amenities while minimizing ecological impact. The architectural intent focuses on integrating the structures with the natural landscape, utilizing modular components to maintain adaptability in construction and operation.

## Spatial Strategy

The design organizes the retreat into a two-story configuration built from seven modular units. The ground floor features a common area for social interaction, kitchen and dining zones to promote communal engagement, and dedicated spaces for relaxation. On the upper floor, sleeping arrangements accommodate both communal and private needs, with individual alcoves designed to enhance privacy. A service module supports essential functions, including water storage and filtration systems integrated with bath facilities.

## Materiality and Sustainability

Attention to material selection plays a critical role in achieving sustainability objectives. Galvanized steel is utilized for roofing and facade elements, ensuring durability and low maintenance. Wooden panels introduce warmth and texture that harmonize with the surroundings, while copper detailing acknowledges local architectural traditions. Large glass windows optimize natural light and provide panoramic views of the mountainous landscape. The design also incorporates systems for rainwater harvesting and solar energy generation, addressing both water management and energy efficiency throughout the year.

The Buildner’s Unbuilt Award 2025: Celebrating Architectural Creativity and Visionary Unbuilt Designs with a Total Prize Fund of €100,000

`
Competition organisers

The Buildner’s Unbuilt Award 2025 is an international architecture competition dedicated to recognizing and celebrating the value of unrealized architectural designs. It invites architects, designers, and students worldwide to submit visionary projects that have not yet been constructed, highlighting the power of ideas and the creativity behind the design process. By focusing on unbuilt work, the competition aims to bring forward concepts that shape the future of architecture and push the boundaries of the profession. 

Participants can compete in three categories based on project scale: Small Wonders (up to 100 m²), Medium Marvels (101–999 m²), and Large Visions (over 1,000 m²). Each category winner will receive €20,000, and additional prizes include honorable mentions, student awards, and a special Best Presentation Award. Winning projects will gain significant international exposure through Buildner’s publicity campaign and a feature article on ArchDaily, providing a unique opportunity to showcase creative ideas to a global audience. 

The Buildner’s Unbuilt Award 2025 encourages entrants to submit any type of unbuilt project, from conceptual visions to detailed designs, celebrating bold innovation without the constraints of realization. Important deadlines: registration closes on October 30, 2025; submissions are due by November 20, 2025; winners will be announced on December 17, 2025.
