Passive Ventilation Through Elevated Truss System and Natural Wood Finishes in Compact Sustainable Living

Project in-detail

An elevated truss system combined with natural wood finishes enhances passive ventilation, creating a compact and sustainable living space tailored for efficient off-grid functionality.
5 key facts about this project
01
Elevated truss system enhances airflow and passive cooling.
02
Integrated rainwater harvesting system ensures water self-sufficiency.
03
Tatami mats are used for both flooring and multifunctional storage.
04
Asymmetrical roof design optimizes solar panel positioning.
05
Sustainable materials include charred wood for longevity and aesthetics.

The TrussTatami project, also known as Auto TT Home, represents a modern approach to sustainable living in Vietnam. This architectural design encompasses a compact 25 square meter footprint, integrating principles of efficiency and self-sufficiency. The project combines traditional concepts with contemporary architectural practices, creating a dwelling that is adaptable, functional, and environmentally conscious.

The primary function of the TrussTatami is to provide a living space that maximizes efficiency while catering to the needs of its inhabitants. The design incorporates elements that support off-grid living, featuring systems for rainwater harvesting and solar energy utilization. The floor plan consists of multifunctional areas designed for relaxation, storage, and daily activities, ensuring that every square meter serves a purpose.

The architectural elements of the TrussTatami project are central to both its aesthetic and functional performance. The use of a truss system made from steel provides structural integrity while allowing for open and flexible interior spaces. The wooden framework contributes to the overall warmth of the design. Large glass openings enhance natural light penetration and offer views of the surrounding environment, fostering a connection between indoors and outdoors.

One of the unique aspects of the TrussTatami project is its integration of the tatami mat concept. By incorporating traditional materials into a modern design, the project highlights cultural relevance while promoting an efficient use of space. The elevated design supports passive ventilation, effectively promoting natural cooling in the tropical climate. This approach to climate-responsive architecture is critical in enhancing the overall livability of the home.

Additionally, the design features an asymmetrical roof that serves both an aesthetic purpose and practical functions, such as water drainage and solar panel integration. This design choice reflects an understanding of local climate conditions while providing a contemporary roof profile. The use of sustainable materials like concrete and wood further demonstrates a commitment to environmental responsibility.

In summary, the TrussTatami/Auto TT Home project effectively combines traditional influences with modern architectural practices to create a unique, functional urban dwelling. The design’s focus on sustainability, coupled with its innovative use of space and materials, sets it apart from typical architectural solutions.

The Mujassam Watan Urban Sculpture Challenge invites architects and designers to create iconic public sculptures for one of two sites in Saudi Arabia: Abu Hadriyah Road or the Tharwa Sea Front in Al-Khobar. Proposals should reflect Saudi identity, culture, and future aspirations.

`

The Mujassam Watan Urban Sculpture Challenge is an international architecture and design competition inviting creatives to shape the future of Saudi Arabia’s public spaces. With a total prize fund of €50,000, the competition calls for sculptural proposals that merge cultural symbolism with innovative design, offering participants a chance to see their concepts brought to life in a rapidly transforming national context.

Organised by Buildner in partnership with the Mujassam Watan Initiative, the challenge focuses on two prominent locations: Abu Hadriyah Road, a major highway and gateway into the Eastern Province, and the Tharwa Sea Front in Al-Khobar, a pedestrian-focused waterfront district. Designers must select one site and develop a sculpture that engages with its surroundings—whether addressing the fast-paced dynamism of a transit corridor or creating moments of interaction along a coastal promenade.

Proposals should be bold, site-specific, and rooted in narrative—drawing on themes such as heritage, national identity, transformation, and dialogue. Environmental responsiveness, material durability, and feasibility are strongly encouraged, as winning projects may be selected for actual construction.

Each submission must include four A2 landscape presentation boards, a cover image, and a written project description. The competition is open to professionals and students alike, working individually or in teams of up to four people. No professional license is required.

Registration is open until July 24, 2025, with final submissions due by August 27, 2025. Winners will be announced on October 1, 2025.
