Shell Duo is a modular housing project situated in Glenorchy, Southern New Zealand. It addresses the growing demand for affordable housing by integrating sustainable design elements with efficient construction methodologies. The project’s main objective is to provide quality living spaces that are adaptable and environmentally conscious. The selection of materials and architectural forms is rooted in a commitment to fostering community while preserving the surrounding natural landscape.

One remarkable aspect of Shell Duo is its modular design, which allows for flexibility in configuration. Each unit measures 6m x 2.4m, facilitating various arrangements that cater to different family sizes and lifestyles. The architecture embraces an aesthetic that harmonizes with the surrounding environment, characterized by curvilinear rooflines that blend with the topography. This design minimizes the impact on the landscape while creating visually engaging forms that attract residents and visitors alike.

The project employs Structural Insulated Panels (SIPs) as the foundational building component. These panels provide both insulation and structural integrity, contributing to energy efficiency. The use of locally sourced timber ensures sustainability, enhancing the region's economy and minimizing transportation emissions. Additionally, the incorporation of zinc metal roofing contributes to the project's durability and requires minimal maintenance over time. Large glass elements are strategically placed throughout the units, allowing natural light to permeate the interiors while connecting residents to the exterior landscape.

The overall design focuses on creating interconnected living spaces that encourage social interaction. The open-plan layout, featuring an integrated kitchen and dining area, promotes communal living. Bedrooms are designed with privacy and comfort in mind, set apart to provide personal retreats. The incorporation of open-air hallways serves to create a seamless flow between spaces, enhancing the residents' experience within the structure.

Uniquely, Shell Duo incorporates renewable energy technologies into its architectural framework. Solar thermal systems, positioned on the roof, provide efficient water heating, while rainwater harvesting systems reduce reliance on municipal water sources. These features align with the project’s sustainable ethos and contribute to lower operating costs for residents. The architecture not only addresses immediate housing needs but also sets a precedent for future developments aimed at ecological and economic sustainability.

For a deeper understanding of this architectural project, readers are encouraged to explore additional details, including architectural plans, sections, designs, and ideas that illustrate the thoughtful processes behind Shell Duo.

Competition organisers

The 10th edition of the MICROHOME architecture competition invites architects and designers from around the world to explore the possibilities of compact, sustainable living. Hosted by Buildner in collaboration with Kingspan and Hapi Homes, this special edition challenges participants to design an off-grid, modular microhome for a young professional couple, with a maximum floor area of 25 m². Designs should prioritize innovation, efficiency, and real-world feasibility. 

A total prize fund of 100,000 € will be awarded, including three main prizes, the Kingspan Award, and the Hapi Homes Award, which will grant 15,000 € and lead to the construction of the selected design. The final registration deadline is September 25, 2025, and winners will be announced on Decebmer 9, 2025. For full competition details and submission guidelines, visit microhome.info.
