A design customization tool is integrated with an online visual and searchable design elements database and collaboration tool over a network. Design elements are defined as single or collective real and/or abstract instances of any product, pattern, attribute, or feature. Methods provide uploading a picture or draw a target design space in digital format to the server for dynamic modification, customization, and realistic and real-time rendition and virtual visualization of design elements placed within the context of the design space. Methods include building a library of design elements and design concepts database showcasing design elements which can be independently used in different target design spaces with realistic rendition.
