C Children enthusiasm for reading must be supported by providing an inviting, comfortable reading space that aligns with their characteristics. however, many children’s libraries still lack a spatial atmosphere that fosters excitement and engagement in reading. this project addresses key challenges in spatial ambience, comfort, material selection, and circulation flow – all of which significantly influence children’s reading experience.the re-design of “rimba baca” children library, located in bandung, aims to create a child-friendly reading space that is both engaging and functional. the concept is developed based on user characteristics to enhance comfort, safety, and reading motivation from an early age. the design follows descriptive qualitative methodology, including data collection, analysis, programming, concept development, design decision-making, and visual representation.the library design adopts the nusantara folklore theme, inspired by keong mas and timun mas stories. it presents a playful and edutaining spatial ambience within a modern contemporary style. folklore narratives are expressed in murals and thematic decorations integrated into interior elements and furniture to create an aesthetic and imaginative reading environment. the outcome of this project is expected to create a children’s reading space that emphasizes on comfort and aligns with sustainable development goals (sdgs) 4 and 9. the project is also planned to be published in a scientific journal.
