Roomie: Interactive 3D Living Space Planning Platform for Smarter Residential Design

Roomie: plan your living space in interactive 3D

Coding Crafts developed Roomie, an interactive 3D space planning platform designed for apartment and dorm residents. The platform enables users to visualize their living spaces with accurate 3D models, experiment with furniture layouts, collaborate with roommates in real time, and make informed furnishing decisions before moving in or purchasing items.

Built using React.js and Babylon.js on the frontend, Java Spring on the backend, and PostgreSQL as the core database, Roomie delivers a high-performance, visually rich, and scalable web experience tailored for modern residential planning needs.

Real-time 3D collaboration inside the browser

One of the primary challenges was creating highly accurate and performant 3D representations of real world living spaces that could run smoothly in a browser without compromising usability. Managing real-time interactions between multiple users within the same space added further technical complexity.

Another challenge involved integrating a complex 3D rendering engine with a responsive web interface while ensuring cross device compatibility and fast load times. Handling structured spatial data and user configurations efficiently at scale also required careful backend and database design.

How we built it: Babylon.js, React, and Java Spring

Coding Crafts leveraged Babylon.js to build optimized, lightweight 3D models that balance realism with performance. React.js was used to create an intuitive user interface that seamlessly integrates 3D interactions with standard web controls.

On the backend, Java Spring was implemented to manage user sessions, collaboration logic, and data flow between the client and server. PostgreSQL was structured to store spatial layouts, user preferences, and shared configurations efficiently, enabling smooth real time collaboration and persistence across sessions.

Extensive performance optimization and testing ensured the platform remained responsive across browsers and devices.

What we shipped: shared 3D rooms with precise layouts

The final solution delivered an interactive web based 3D space planning platform that allows users to visualize apartments and dorm rooms with precision. Users can rearrange furniture, collaborate with roommates, and explore furnishing options in a shared virtual environment.

Roomie significantly improves decision making for residents by reducing uncertainty around space utilization and furniture fit. For property managers and housing providers, it enhances user engagement and adds value through an innovative digital experience.

The outcome: furnishing decisions made with confidence

Roomie demonstrates Coding Crafts’ expertise in combining advanced 3D technologies with scalable web architecture. By integrating Babylon.js, React.js, Java Spring, and PostgreSQL, the team delivered a robust, user friendly platform that transforms how people plan and experience their living spaces. The project highlights Coding Crafts’ ability to solve complex technical challenges while delivering meaningful real world impact through thoughtful digital solutions.
