Rainwater Collection and Metal Structure in Flexible Compact Living

Project in-detail

With a revolving platform for versatility and a commitment to sustainability through rainwater collection and a durable metal structure, this compact living solution effectively addresses modern housing needs.
5 key facts about this project
01
Modular design allows for easy reconfiguration between day and night functions.
02
Utilizes a rainwater collection system for enhanced water efficiency.
03
Constructed with a durable metal framework for longevity.
04
Incorporates a revolving platform that serves dual purposes as a terrace and sunbreaker.
05
Large windows provide passive solar heating while maximizing natural light.

HIDEAWAY is a compact living solution that prioritizes flexibility and sustainability. Located in varied settings, the design showcases how a small space can meet diverse needs. With a footprint of 25 square meters, it addresses modern urban living by integrating adaptable features and eco-friendly practices.

Spatial Modularity

The concept is based on spatial modularity, using mobile furnishings to change the interior layout from day to night. This flexibility supports different activities and helps users customize their living space. A compositional grid organizes the area, optimizing functionality while keeping the environment open and inviting.

Sustainable Construction

The building features a low environmental impact, constructed with a metal framework and recyclable materials. This choice enhances its durability and aligns with current sustainability goals in architecture. Natural insulation helps regulate indoor temperatures, making the space comfortable throughout the year.

Energy Efficiency Features

Energy efficiency is a core aspect of the design. Large windows allow for passive solar heating during colder months. A rainwater collection system reduces water usage, while photovoltaic panels generate electricity. The addition of a solar thermal system ensures a supply of hot water, making the house self-sufficient and environmentally friendly.

Unique Design Elements

One notable feature is the revolving platform that serves as both a terrace and a sunbreaker. This element adds outdoor usability while providing shading to reduce heat from the sun. It illustrates the project’s commitment to creating spaces that are not only functional but also enhancing the quality of life for users.

HIDEAWAY combines practicality and sustainability, resulting in an architectural solution that effectively meets contemporary living challenges. The focus on modularity and energy efficiency creates a harmonious balance between the indoors and the outdoors.
