Superinsulated Single-Level Living with Structural Insulated Panels

Project in-detail

With a focus on superinsulated performance and modular construction techniques, the design integrates structural insulated panels to create accessible, single-level living units that effectively address the need for affordable housing in urban environments.
5 key facts about this project
01
Superinsulation techniques achieve a six-star energy rating.
02
Design eliminates stairs for full accessibility on one level.
03
Modular construction allows for rapid onsite assembly.
04
Standardized components reduce overall construction costs.
05
Community integration enhances social interaction among residents.

The project focused on Accessory Dwelling Units (ADUs) in Anchorage, Alaska, addresses the growing need for affordable housing within urban communities. These small residential units are designed to fit on existing single-family lots, thus allowing for increased density while minimizing the impact on surrounding areas. The design aims to offer practical living solutions, making efficient use of space while promoting community integration.

Accessibility

Accessibility is a core feature of the design, achieved by removing stairs and ladders. Everything necessary for daily living is arranged on one level. This layout makes it easier for people, including those using mobility aids, to move freely. A low foundation system reduces the need for ramps, creating a more inviting living space that accommodates all residents comfortably.

Affordability

To tackle affordability, the design focuses on a smaller footprint. This results in lower construction costs and reduced long-term expenses. By using standardized materials such as windows, doors, and cabinets, building becomes more cost-effective. The project employs modular construction techniques, allowing quick assembly on site to minimize construction time and disruption to the neighborhood.

Efficiency

Energy efficiency is emphasized throughout the project. The ADUs achieve a six-star energy rating, indicating a meaningful reduction in energy use. Techniques like superinsulation contribute to thermal performance, while Structural Insulated Panels (SIPs) are utilized for walls and roofs. The inclusion of high-efficiency water heating systems, along with the option for solar photovoltaics, provides sustainable energy solutions that can adapt to homeowners’ financial situations.

Design Detail

The open-plan layout of the ADUs is a key design element, allowing for efficient use of space. This arrangement combines areas for cooking, sleeping, and gathering, promoting a sense of community among residents. The thoughtful organization of these units not only fulfills practical needs but also encourages social interaction, contributing positively to life in the neighborhood. The design reflects a deep understanding of urban living challenges while enhancing the quality of life for those who inhabit these homes.

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.
