The article is devoted to the architecture of an intelligent system based on Hybrid Intelligent Information System approach. The article expands the basic Hybrid Intelligent Information System approach by adding the ability to work with multiple environments, the granular-metagraph approach is also proposed. The main provisions and definitions of granulation of information, the basics of the metagraph model, and the main provisions of the basic approach of Hybrid Intelligent Information Systems are briefly considered. The formal environment model definition is given. Various multi-environmental Hybrid Intelligent Information System architecture alternatives are considered in detail. Four architecture alternatives are proposed: architecture with separate modules of the subconsciousness, architecture with a monolithic module of the subconsciousness, architecture with partially monolithic modules of the subconsciousness, architecture with a hierarchical module of the subconsciousness. The granular-metagraph architecture of the Hybrid Intelligent Information System is proposed and it is shown that the basic properties of information granulation are holds for it.
