The Micro Ambyar Home is a reflection of the Javanese concept of AMBYAR, which denotes fragmentation and separation. Located alongside the Kalibokor River in Kertajaya Village, Surabaya, the home addresses the challenges of urban living in a rapidly growing metropolitan area. The design aims to function as a compact, flexible residence that adapts to the varying needs of its occupants while promoting environmental sustainability.

Design Concept

The focus of the Micro Ambyar Home is on adaptability. With measurements of 2.5 by 5 meters, the structure can change in size and function, catering to the requirements of its residents. This flexibility allows for a dynamic use of space within a small footprint. The layout is thoughtfully divided into public and private areas, providing opportunities for social interaction and personal privacy.

Spatial Organization

Inside, the layout features multifunctional spaces that combine living, working, and sleeping areas. These spaces are cleverly arranged to maximize usability. There are areas designated for essential functions like a kitchen and a toilet, ensuring privacy when needed. This organization makes the home practical for everyday life, particularly for those with busy schedules.

Sustainability and Energy Efficiency

Sustainability is a key element in the design of the Micro Ambyar Home. The building operates on an off-grid energy system that uses solar power, reducing dependence on traditional electricity sources. This aspect not only lowers the environmental footprint but also meets the increasing demand for energy-efficient housing solutions in modern times.

Material Selection

The choice of materials used in the Micro Ambyar Home supports its intended functionality and appearance. Aluminum frames are used for the windows, providing strength and a modern aesthetic. The roof is made of black-coated metal, which is 0.35 mm thick, offering durability and contributing to the overall design. Waterproof board partitions allow for effective division of space while resisting moisture. Flooring made of FERGIO Type Willow Wood adds warmth to the interior. The structural framework utilizes U runners and metal studs, which enhance stability and support.

The Micro Ambyar Home enables occupants to interact with their space in ways that accommodate different lifestyles and preferences. It is designed to encourage a balance between functionality and comfort, making it suitable for urban living.
