The architectural project "Rumah Baru" emerges from the pressing need for sustainable housing while addressing the unique challenges presented by the transition of the Indonesian capital from Jakarta to East Kalimantan. With a focus on environmental responsiveness, this micro home serves as a pioneering model that blends modern design with traditional Indonesian architectural elements. Its fundamental representation lies in creating a harmonious balance between human habitation and the surrounding natural landscape, encapsulating resilience in the face of urban migration while promoting ecological sustainability.

This project functions not only as a residential dwelling but also as a prototype for future housing solutions in rapidly urbanizing regions. It is designed to accommodate the inflow of individuals moving from Jakarta by providing a model that emphasizes sustainability, community engagement, and cultural relevance. The layout promotes social interaction, making it suitable for both individual families and larger communal living arrangements.

At the heart of Rumah Baru's design is its unique architectural form. The asymmetrical, sloped roofs are aesthetically pleasing while serving practical purposes such as enhancing natural ventilation and rainwater drainage. The first floor features an open-plan living area that combines kitchen, dining, and living spaces, allowing for flexibility and interaction among the residents. Large sliding glass doors create seamless transitions between indoors and outdoors, fostering a connection with the lush rainforest environment and supporting outdoor living experiences.

The second floor houses private sleeping areas, ensuring residents can retreat to personal spaces while still being part of a communal atmosphere. The use of light wood finishes throughout amplifies the warmth of the interiors, while large windows promote ample natural light, reducing reliance on artificial lighting and fostering a healthy living environment.

In terms of materiality, Rumah Baru incorporates a thoughtful selection of sustainable resources that reflect its ecological commitment. The application of fiberglass for the exterior skin allows for durability and energy efficiency. Wood is used extensively for both structure and finishing, reinforcing a sense of local craftsmanship while connecting the architecture to its natural surroundings. Photovoltaic panels installed on the roofs collect solar energy, making the home self-sufficient in energy production, while rainwater collection systems provide vital water resources.

Unique design strategies are evident throughout the project. The integration of natural ventilation concepts promotes air circulation, significantly reducing the need for mechanical cooling systems often seen in modern architecture. This approach not only reduces energy consumption but also contributes to improved indoor air quality, which is essential for health and well-being. Moreover, the elevation of the home above ground level helps mitigate flood risks, a crucial consideration in a tropical climate prone to heavy rainfall.

In terms of its impact on the community, Rumah Baru serves as a catalyst for social cohesion in developing urban settings. Its communal spaces encourage interaction among residents, fostering a sense of belonging and support which is vital during times of transition. The positioning of the unit along coastal areas leverages the stunning natural vistas, enhancing the appeal for future inhabitants while confirming the project's commitment to environmental harmony.

This micro home is not just a response to housing needs; it offers insights into a sustainable lifestyle adapted to local conditions. With Rumah Baru, there exists a clear potential for scalability and adaptability, allowing for further developments that respect both the ecological landscape and traditional lifestyles of the community. Those interested in exploring the architectural plans, sections, and overall designs of this project will find a wealth of information that illustrates how thoughtful architecture can respond to urgent social and environmental needs. It invites further investigation into innovative architectural ideas that could pave the way for future endeavors in sustainable living.
