This study investigates the dynamic interplay between architectural elements and narrative construction in J.R.R. Tolkien’s novel The Hobbit (1937) and its cinematic adaptations directed by Peter Jackson. By focusing on both literary and cinematic mediums, this research elucidates how architectural elements contribute to world-building, character development, story progression, and thematic expression. The fantasy genre, with its potential for spatial constructs, provides fertile ground for this exploration. Through comprehensive analysis, it is revealed that Tolkien’s strategic use of spaces such as the Shire, Erebor, and the Woodland Realm enhances the narrative's depth and realism. These spaces are integral to the narrative, reflecting the cultural and moral attributes of their inhabitants and influencing the story's progression. In parallel, Jackson's films reinterpret these architectural spaces, employing cinematic techniques to amplify their visual and emotional impact. The adaptation showcases the integration of architectural elements with narrative and character development, creating a different kind of experience for viewer. This study adopts an interdisciplinary approach, drawing from literary analysis, film studies, and architectural theory, to offer new insights into the significant role of architecture in storytelling. The research highlights how architectural principles are translated into narrative devices in literature and visual representations in film. The findings underscore the transformative potential of architectural elements in narrative construction, highlighting their importance as central components rather than mere background settings. This research contributes to a deeper understanding of the multifaceted relationship between architecture, literature, and film, and calls for further interdisciplinary exploration to fully appreciate the impact of spatial dynamics in narrative art.
