The Design Memory Platform

GAAD, Genetic Aided Architectural Design, is a design memory platform. It records the complete journey of a design: every option considered, every path explored, so that history can be replayed and learned from. One principle underpins it: decisions become data, and in time, knowledge.

GAAD began as an MSc in Architecture and Computing at the University of East London. In 1994, the thesis Digital Evolutions set out an idea that was unusual at the time: that a design could be grown through evolution, with the designer as the fitness function, and that every design decision could be recorded, replayed and learned from. This was long before AI was part of the conversation.

The question behind it, first asked in 1992, has not gone away: why do we remember the final design, but lose the thinking that created it?

Most design tools, including today's AI, learn from finished artefacts. GAAD is built around the why, not just the what. It captures design knowledge and preserves the full design journey, so a design can be understood, not just reproduced. The belief is that the next generation of design tools won't simply generate ideas; they'll remember the decisions that created them.

GAAD is founded and built by Miles Walker. It began with the instinct of an architectural technician: an interest in the detail. That same instinct took him into BIM, where he was an early pioneer from 2003, leading it for more than twenty years across major projects in London and international design practices and construction firms, and it runs straight through to GAAD: capturing the detail of a design decision, not just its outcome.

How GAAD is built

It is easy to think working with AI means giving it a prompt and getting an answer. GAAD works differently. It runs on a small team of four, each with a job of their own: Miles Walker as Chief Architect, deciding and testing; Claude as Specification Owner, keeping the records and writing the code; ChatGPT as Architecture Reviewer, a second pair of eyes; Claude Code as Code Technician, working locally with its hands on the estate, building at the bench on Miles's own machine and checking every script against the specification before it reaches him. GAAD began with the instinct of a technician, and its newest seat carries the same word.

The work itself moves in one loop: direction from the Chief Architect, specification and code from Claude, a validation gate on every handover, testing in Blender, and everything captured into the records. The same records you can read on this site.
