Palimpsest

LLM-Driven Timber Evolution

AI/LLM + Education + Architecture

PALIMPSEST integrates multimodal large language models (MLLMs) and computational geometry, pioneering a construction system for adaptive upcycling of urban waste. Users upload data of discarded components; MLLMs co-trained with architectural and structural experts identify boundaries, cross-sections, and load-bearing characteristics, cataloging them into a parametric material library.

In response to spatial requirements, the algorithmic engine conducts geometric reconciliation and structural optimisation in a virtual environment, aggregating salvage into stable parametric configurations.

At the physical stage, the system synthesises 3D-printed nodes combining structural connection and tolerance compensation and outputs standardised fabrication code, replacing manual joinery and destructive processing. A diagrammatic assembly manual guides users step-by-step toward safe construction.

By integrating perceptual analysis, generative form-finding, distributed additive manufacturing, and intuitive assembly, this closed-loop architecture dismantles professional barriers, transforming urban waste into sustainable tectonic assets for future net-zero urban development.

Background

Globally, construction waste accounts for 30% to 40% of urban solid waste, yet most demolition materials have not effectively entered the new construction cycle system.

Design Trajectory

Palimpsest proposes a circular material system for construction and demolition waste, aiming to transform discarded building materials into reusable design assets.

Digital Platform

Six interconnected interface stages guide users from material input to final assembly, from physical resource to digital asset, design component and buildable system.
