Project in-detail

The use of a collapsible translucent polypropylene dome and an integrated greywater system defines a compact microhome crafted for off-grid living.
5 key facts about this project
01
The microhome features a continuous ring circulation pattern for efficient movement.
02
A translucent polypropylene dome allows for adaptable light and ventilation.
03
Integrated greywater collection funnels used water into a ring-ditch system.
04
The platform serves multiple functions, including storage, seating, and lounging.
05
The design accommodates a transient lifestyle with an off-grid capability.

The Accordion Bubble microhome is designed to address the increasing need for flexible and sustainable living arrangements. With its compact form, it promotes an off-grid lifestyle that encourages a connection between indoor and outdoor spaces. The structure integrates essential amenities while remaining adaptable to various environments, making it suitable for those who value mobility and simplicity.

Design Concept

The core of the Accordion Bubble includes all necessary living functions, such as a kitchenette, washroom, shower, and a queen-size bed. This central arrangement of amenities responds well to basic human needs while optimizing space. The design allows for thoughtful interaction within a limited footprint, contributing to a practical living experience.

Circulation and Engagement

The design sets itself apart by using a continuous ring for circulation around the core unit. This creates a smooth flow of movement throughout the microhome, reducing chances of congestion for its occupants. The platform surrounding the core not only supports transit but also serves as a storage solution, helping to keep the area organized and functional.

Material and Structure

A significant aspect of the microhome is its translucent polypropylene dome, which is lightweight and collapsible. This material allows for easy transportation and adaptability to different weather conditions. The dome can open to various degrees, making the living space flexible and enhancing comfort during different times of the day.

Water Management System

The design includes a system for managing greywater, which is carefully collected and funneled into a ring-ditch embedded in the platform. This feature highlights an awareness of environmental concerns and promotes sustainable water use. The platform also serves various functions, such as seating and lounging space, further demonstrating the microhome’s adaptability and resourcefulness. The variable height of the platform enhances its usability while contributing to the overall design coherence.
