Design a simple yet charming Indonesian-style house with a budget of 50 million rupiah. The house should feature traditional elements like a tiled roof, wooden doors, and large windows to allow natural light. The layout should be compact but functional, with a small living area, one or two bedrooms, and a basic kitchen. Use affordable and locally sourced materials, such as bamboo or recycled wood, to maintain cost-effectiveness. The overall aesthetic should be warm and inviting, reflecting the cozy, down-to-earth spirit of Indonesian homes.
