Central Column Supporting Photovoltaic Glass and Rainwater Systems in Circular Residential Design

Project in-detail

A central column integrates energy-generating photovoltaic glass and rainwater systems within a circular form, optimizing sustainable living in a contemporary residential environment.
5 key facts about this project
01
A central structural column houses essential utilities while supporting the radial design.
02
Photovoltaic glass is integrated into the facade for energy efficiency.
03
Rainwater harvesting systems are seamlessly incorporated into the building structure.
04
A circular layout promotes unobstructed views of the surrounding landscape.
05
Prefabricated components reduce construction time and environmental impact.

### Project Overview

The Ring House, located within a carefully considered landscape, integrates contemporary design with sustainable practices to create a cohesive residential environment. The structure's circular form reflects a commitment to functionality while fostering an intrinsic connection with its surroundings. With an emphasis on energy efficiency and self-sufficiency, the design seeks to unify users with nature and address modern living requirements.

### Design Philosophy and Spatial Organization

The design philosophy centers around the concepts of "funnel" and "diversion," optimizing the flow of rainwater and electricity through the structure. Organized around a central column, the layout promotes a clear spatial hierarchy while facilitating movement and interaction among inhabitants. This radial organization enhances the living experience, allowing for flexible and efficient use of space. The layout strategically delineates functional areas—such as dining, cooking, and sleeping zones—while maximizing access to natural light and ventilation through abundant glazing.

### Material Selection and Sustainability Features

Materiality is central to the Ring House’s design integrity, incorporating a range of thoughtfully selected components that enhance both functionality and aesthetic coherence. Concrete serves as the foundational element, providing stability, while steel plate profiles form the outer shell, balancing strength with a modern appearance. The use of power generation glass integrates photovoltaic cells, enhancing the structure’s energy efficiency. Additionally, galvanized steel fixtures contribute to durability, complementing the residence's natural context. Innovative systems for rainwater collection and energy generation emphasize the project's commitment to sustainability, ensuring operational independence while minimizing environmental impact.

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.
