Floating Microhome with Water Harvesting and Integrated Vegetation

Project in-detail

Floating on a modular cube pontoon system, the microhome captures rainwater and seawater while integrating vegetation for cultivation, providing a self-sufficient living space in vulnerable coastal environments.
5 key facts about this project
01
Floating structure adapts to changing water levels.
02
Integrated system captures and filters rainwater and seawater.
03
Exterior features vegetation pots for sustainable cultivation.
04
Solar panels provide renewable energy for off-grid living.
05
Designed for efficient use of space for two occupants.

The Lotus is designed as a response to rising sea levels caused by climate change. Positioned in coastal areas or lakes, it serves as a modular microhome that floats on water. The design draws inspiration from the lotus flower, symbolizing both beauty and resilience. This dwelling aims to support a self-sufficient lifestyle while connecting with the natural environment.

Structural Framework

The structure utilizes a modular cube pontoon system as a floating platform. This allows it to remain stable and buoyant, even when water levels fluctuate. The design enables quick setup and avoids significant disruption to the surrounding ecosystem. By floating, it adapts effectively to coastal conditions, responding to the challenges of climate change.

Sustainability Features

A notable feature of The Lotus is its water harvesting system. It captures rainwater and seawater for everyday use, reducing the need for external water sources. This efficient use of resources aligns with sustainable living practices. Additionally, vegetation pots are integrated into the exterior, allowing for plant growth using the filtered water. This not only provides greenery but also fosters local biodiversity.

Energy Efficiency

Solar panels are installed on the roof to generate renewable energy for the home. This feature enhances the independence of The Lotus, making it less reliant on traditional energy systems. The integration of both water and energy solutions showcases a comprehensive approach to sustainable living, addressing multiple environmental concerns.

Interior Organization

Inside, The Lotus is carefully planned to optimize space for daily activities. It features separate areas for sleeping, living, working, cooking, dining, a bathroom, and storage. This thoughtful layout accommodates two occupants, balancing work and relaxation in a compact environment.

Every aspect of The Lotus reflects a commitment to practical and sustainable living, with lush vegetation pots adorning the exterior and enhancing both the look and ecological impact of the design.
