VoxBox is a free CAD application designed for Windows that allows users to explore and design interior spaces using a comprehensive catalog of VOX furniture. This multimedia tool categorizes a wide range of items, including wardrobes, desks, chairs, and decorative elements, making it easy to select and place furniture according to various styles and characteristics. Users can create a room layout by defining dimensions, adding windows and doors, and customizing wall and floor colors.

The application provides three viewing angles—overhead, interior, and perspective—allowing for a versatile design experience. Users can navigate through their designed space using direction arrows, facilitating an immersive visualization of their interior design. VoxBox also offers the option to save designs as BMP files, making it accessible for users who wish to create and share their interior concepts, regardless of any purchase intentions.
