Adaptive Reuse of Jengki House into a Communal Café: A Case Study of Seven Speed Coffee

Abstract

This study investigates the adaptive reuse of a Jengki-style residential house into a communal café, focusing on Seven Speed Coffee in Kebayoran Baru, Jakarta. Rapid urban development has encouraged the conversion of residential buildings into commercial and public spaces. This research aims to analyze spatial transformation, functional adaptation, and architectural preservation resulting from adaptive reuse. A qualitative descriptive method with a case study approach was applied through field observations, photographic documentation, and literature review. The findings indicate that the building successfully maintains its original façade, roof form, and ventilation elements characteristic of Jengki architecture, while accommodating new functions through minimal structural intervention. Interior modifications, including epoxy flooring, exposed brick walls, and modern lighting systems, enhance usability without compromising historical identity. This study concludes that adaptive reuse contributes positively to heritage conservation, sustainable urban development, and socio-cultural continuity in urban environments.
