Project Overview<\/h2>\n\n\n\n

Project Geo-stitch explores architectures conceived through the restitching of waste mine tailings across a geological timescale. The research intervenes in the most recent anthro-geological cycle of the Kentucky Corbin Sandstone, which is exposed through mountain-top removal. Weathered red sandstone is pulverized as a cement aggregate, while newly unearthed grey sandstone is intelligently placed as structural elements. Geostitch then develops computation and additive manufacturing workflows to generate architectures through re-stitching the red and grey sandstones. The project allows for questions of terrestrial rehabilitation, the metabolizing of irregular stone, and the material affordances from reduced cement, formwork, and transportation in construction.<\/p>\n<\/div>\n\n\n\n

Project Journey<\/h2>\n\n\n\n

Geo-stitch began in Jonathan Grinham\u2019s GSD Fall 2024 course \u201cCircuits and Loops: Towards a Regenerative Architecture\u201d<\/em> and advanced into Maddie Farrer\u2019s M. Arch I 2025 thesis Reshaping Remnants<\/em>. The thesis critiques architecture\u2019s teleological mindset, proposing a practice of material inheritance, ecological realities, and deep time: using discarded stone from post-extractive Kentucky landscapes and 3D-printing cement between irregular boulders to restore watersheds and support human and non-human needs. Building on this research, the team received a residency at Autodesk Technology Center Boston, where the final prototype is being fabricated using the Build Additive, large format cement 3D-printer. An installation of the prototype at House Zero is planned for the 2026 Spring semester.<\/p>\n\n\n\n

Working with Autodesk Research, MIT’s Center for Advanced Production Technologies (APT), and Build Additive, the GRG team is developing a custom 3D-printing workflow including: 1) in situ stone scanning\/digitization, 2) automated tool path planning, and 3) co-printing cementitious material and stone using the large format 3-axis Build Additive Machine.
