A system can receive network build sheets corresponding to proposed network architectures for a computer network. The system can aggregate the network build sheets to generate the holistic build data for the computer network. The system can receive a request to access a user interface for displaying the holistic build data. The system can determine an access level associated with the request. The system can generate the user interface that includes a graphical representation of at least a portion of the holistic build data. The graphical representation can be customized based on the determined access level.
