Off-Grid Living Enhanced by SIP Technology and Scaffolding Framework

Project in-detail

Featuring modular construction with structural insulated panels and a scaffolding framework, these compact units offer off-grid living solutions tailored for young residents in Lisbon.
5 key facts about this project
01
Each microhome is prefabricated in six parts, allowing for rapid on-site assembly in just four hours.
02
The design employs structural insulated panels for enhanced thermal efficiency and low energy consumption.
03
Solar panels on the roofs generate around 50% of the residents' energy needs, promoting sustainability.
04
Advanced rainwater harvesting systems can collect up to 7,300 liters annually, supporting off-grid living.
05
The use of H-beams creates a unique framework that facilitates communal pathways between units, fostering interaction.
The Microhomes project in Lisbon, Portugal, addresses the pressing housing crisis affecting young residents. Designed as compact modular units, these homes are specifically tailored for individuals earning limited incomes. Each unit, measuring under 25 square meters, incorporates efficient use of space with a focus on affordability, sustainability, and community.

The architecture of the Microhomes is characterized by a unique modular design that allows for rapid assembly. Comprised of prefabricated components, which are constructed off-site and quickly assembled with minimal labor, this design approach significantly reduces construction time to only four hours. This efficiency addresses the immediate need for housing while providing a viable solution for urban living.

Innovative Community-Centric Design

One of the defining features of the Microhomes project is its "Parasite" concept, which leverages existing urban infrastructures and underutilized spaces. By positioning these compact homes in a cohesive layout reminiscent of books on a shelf, the design fosters a sense of community among residents. The integration of H-beams for structural support promotes open pathways for movement and interaction, aiming to break down social barriers in urban settings.

Sustainability is a cornerstone of the design. Each Microhome is equipped with solar panels on the roof that generate sufficient energy to meet around 50% of the residents' energy needs, allowing for a small surplus that can be returned to the grid. Additionally, advanced water harvesting systems are integrated into the design to collect rainwater, supporting the units' off-grid capability.

Architectural Efficiency and Materiality

The material strategy employed in the Microhomes is both practical and effective. The primary structure utilizes structural insulated panels (SIPs), providing excellent thermal insulation while minimizing energy consumption. PVC double-glazed windows enhance the overall energy performance and comfort for the occupants. The use of durable materials like reinforced PVC frames, aluminum strips, and acoustic seals ensures longevity and comfort within each compact living space.

The kitchen and storage facilities are integrated into the modular design to maximize utility without sacrificing space. Prefabrication techniques allow for these essential amenities to be pre-installed, streamlining the assembly process and further optimizing the living environment.

The Microhomes project in Lisbon stands as an effective response to housing needs through architectural innovation, sustainable design, and community engagement. For those interested in exploring further, reviewing the architectural plans, sections, and designs will provide deeper insights into the unique strategies employed in this project.

Design a new small-scale home concept in the 10th edition of MICROHOME — 100,000 € prize + construction

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.
