Wigwam-Inspired Microhome Featuring Goat Wool Insulation and Rainwater Recycling

Project in-detail

Constructed with a wigwam-inspired shape and advanced goat wool insulation, this microhome utilizes rainwater recycling to promote sustainability while providing cozy year-round living near Lake Ontario.
5 key facts about this project
01
Wigwam-inspired shape enhances cultural connection to the site.
02
Constructed with local wood for reduced environmental impact.
03
Advanced goat wool insulation improves energy efficiency.
04
Rainwater recycling system maximizes water resource sustainability.
05
Modular layout allows flexible use of living spaces.

The microhome located near Lake Ontario provides a thoughtful blend of traditional design and modern sustainability practices. Set on an island, this site enhances the connection to the surrounding nature. The design takes inspiration from the wigwams used by historical semi-nomadic communities. It serves the function of year-round living, accommodating the local climate's temperate summers and harsh winters.

Materials and Construction

Locally sourced materials play a key role in the construction of the microhome. The external walls are primarily made of wood, which provides an 8-centimeter thickness for effective thermal insulation. Additional layers include 1 cm of plaster, 3 cm of plasterboard, and 8 cm of goat wool insulation, making the structure both energy-efficient and comfortable. Along with 3 cm of wooden board, there is a 0.5 cm breathable waterproof sheath. A framework of vertical and horizontal strips, measuring 3 cm, supports a roof cover of 7 cm.

Water and Energy Systems

A well-designed water management system is central to the microhome. Water is drawn from the urban aqueduct and is supplemented by a rainwater recycling feature. This system includes a filtering phase to remove impurities, a storage container for collected rainwater, and a pumping mechanism for distribution. A comprehensive piping network ensures that water is readily available throughout the living space, aligning with principles of resource conservation.

Photovoltaic Integration

To enhance energy efficiency, high-efficiency photovoltaic panels are incorporated into the design. These panels feature optimized PERC cells, which significantly reduce current loss and maximize power output under varying conditions. They are made with 3.2 mm tempered glass, providing mechanical durability and transparency. These panels are also designed to withstand high temperatures and potential hail damage, fulfilling the microhome’s energy needs while staying within sustainable practices.

The layout of the microhome offers flexibility for its occupants. It allows for adaptability in how living spaces are utilized and arranged. Natural light and environmental integration are carefully considered, creating a calm interior atmosphere. This focus on the relationship between indoor and outdoor areas enhances the overall living experience, making the architecture feel inviting and connected to the landscape.

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.
