The presented research study tackles the topic of economic and material sustainable development in the built environment and construction industry, by introducing and applying the concept and the potential of Non-Fungible Tokens (NFTs) on blockchain within the early stages of the design process via the interface of common design software. We present a digital infrastructure layer for architectural assets and building components that can integrate with AEC supply chains, enabling a more effective and articulated development of circular economies. The infrastructure layer consists of a combination of topology graphs secured with a blockchain. The paper concludes with a discussion about the possibilities of material passports as well as circular economy and smart contracts as an infrastructure for whole lifecycle BIM and digital encapsulation of value in architectural design.
