Cor-Ten Steel and Modular Design Integrate in a Triangular Residential Structure

Project in-detail

With a distinctive triangular configuration and modular construction of Cor-Ten steel, the design creates adaptable residential space that emphasizes natural light and flexibility in living arrangements.
5 key facts about this project
01
Modular units allow for easy expansion and customization based on user needs.
02
The central triangular light well enhances natural lighting throughout the living spaces.
03
Cor-Ten steel develops a unique patina, contributing to the structure's visual character over time.
04
Each module maintains precise dimensions for efficient construction and integration.
05
Elevating the structure by 50 centimeters improves interaction with the surrounding landscape.

The design features a modular configuration based on geometric principles, particularly the triangle, within a contemporary residential setting. It is adaptable, meeting the needs of modern living while maintaining stability and visual appeal. Each component is thoughtfully integrated, resulting in a space that balances practicality with aesthetic coherence.

Concept and Geometry

At the foundation of the design is a modular system that employs shipment containers as the primary building blocks. These containers can be arranged in various ways, allowing for customization according to the user’s preferences. The arrangement includes three main modules that revolve around a central triangular light well. This element acts as a focal point, enhancing the feel of the space by allowing natural light to filter in and uplifting the overall atmosphere.

Materiality

Key to the design is the choice of materials, particularly the use of Cor-Ten steel sheet. This material, consisting of copper, chromium, nickel, and phosphorus, is known for its durability and resistance to corrosion. As it ages, the steel develops a unique patina that adds character to the structure. This feature not only contributes to its visual interest but also reduces the need for maintenance, supporting the design's sustainable approach.

Spatial Dynamics

The layout consists of modules measuring 2.44 by 6.06 meters, leading to larger configurations of 4.88 by 6.06 meters with a total height of 3.10 meters. Positioned 50 centimeters above the ground, the structure connects effectively with its surroundings, enhancing the interplay between indoor and outdoor spaces. The design creates a complex exterior that interacts with natural light, adding depth and richness to the experience within.

A notable aspect of the design is the triangular light well, which separates private night spaces from open day areas. This well invites light into the home, creating warmth and openness throughout. The careful combination of geometry, modularity, and material choice culminates in a structure that reflects a well-considered approach to contemporary living.

MICROHOME 10: Celebrating Small-Scale Living with €100,000 Prize Fund and Kingspan’s Innovation

`
Competition organisers

The MICROHOME 10 competition invites participants to submit visionary designs for off-grid, modular microhomes that push the limits of sustainable, small-scale living. Organised by Buildner in partnership with Kingspan and Hapi Homes, this tenth edition sets the challenge of designing a dwelling for two people within a maximum floor area of 25 m², encouraging bold solutions adaptable to any urban or rural location. The competition continues Buildner’s mission to foster innovative approaches to compact, energy-efficient housing that can address pressing global challenges.

This year’s edition offers a generous total prize fund of €100,000, including the Kingspan Award for designs that integrate high-performance Kingspan products and the Hapi Homes Award for a project selected for real-world construction. In addition to cash prizes, the winners gain international exposure through Buildner’s media partnerships, publications, and a dedicated MICROHOME magazine, further amplifying their ideas to the wider architectural community.

Key dates for MICROHOME 10 include the closing date for registration on 25 September 2025, the submission deadline on 29 October 2025 (11:59 p.m. London time), and the announcement of winners on 9 December 2025. These milestones ensure participants have clear timelines to develop and present their concepts, with early registration discounts available to support students and emerging designers worldwide.
