Team Name
Team B
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.
PALIMPSEST: Project Overview
PALIMPSEST: Project Overview
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.
Palimpsest reusing Loop
Reclaimed material is scanned and indexed on digital platforms; Khora turns a user's need into a buildable, scored configuration; connectors let it be assembled by hand, then taken apart and written again.
Material Read as Resource
Models, prints and scenarios from Palimpsest gathered in one studio: timber aggregations, connector trials and the canopy, market and shelter cases, each showing reclaimed material read as a resource, not waste.
Design Anywhere, Build with What You Find
Accessible across desktop, tablet and mobile, Palimpsest turns ideas into reality through material scanning, digital design and connector fabrication—allowing people to design with available materials wherever they are.
From Physical Material to Digital Passport
Upload material images by phone or computer, together with basic information. Palimpsest generates a 3D model, analyses the material with AI, and creates a digital Material Passport for future design and reuse.
Discover and Connect Distributed Materials
Beyond personally uploaded materials, users can explore nearby material repositories through the map, connecting distributed resources and increasing the opportunities for existing materials to be reused.
Co-design with Materials and AI
Select available materials and discuss your needs with the AI assistant. Through multiple rounds of conversation and model generation, choose and refine a preferred design before moving on to connector matching and generation.
Round 3 Training: A Library of Timber Units
Between prompts and outputs, modular units made from timber pieces of varied sizes train the LLM to read dimensions, joints and spatial logics, turning scrap wood into durable, usable and aesthetic structures across many sites.
Continuous Topological Morphing of Architectural Forms
Generative model latent space reveals topological morphing. Four corner models are evaluated by 18 rules; 60 interpolated frames create continuous deformation. The LLM generates a 64-frame sequence maintaining valid tectonics beyond modelling limits.
Round 4 Training Process Selected By LLM and Human
Fidelity Evaluation: Pareto Frontier of Voxel-to-Timber Conversion
Voxel-to-timber fidelity evaluation covers 488 assessments. X-axis shows recall, Y-axis fidelity IoU; iteration rounds track improvement. The Pareto frontier shows convergence, with recall rising 71% to 97.8% and IoU 27.8% to 48.7%.
End-to-End Generative Timber Design Pipeline: Multi-Stage Visualisation
The full generative workflow is visualised across four stages. S1 maps prompt embeddings; S2 plots semantic scores for 18 rules across 161 voxel designs. S3 runs AABB & SAT tests; S4 presents timber count distributions across 327 designs.
