Inspiration

Three words—architecture×archive×hive—sparked archhive, but the form it takes is an architecture-focused social network. Existing platforms like Instagram scatter building shots without context; we envisioned a hive-mind archive where enthusiasts, professionals, and tourists publish their encounters, articulate why a space moves them, and collectively elevate architectural discourse.

What it does

Language unlocks observation – forcing ourselves to verbalize space sharpened our design eye.

Micro-communities beat mass feeds – early testers valued niche curation over algorithmic noise.

Metadata is storytelling – tags like architect, era, or material turn a simple snapshot into research-grade data.

How we built it

Rapid Figma prototyping (1 week) to pin down flows for logging, tagging, and commenting.

Flutter front-end for cross-platform speed; Firebase handles auth and real-time hive feeds.

Serverless OCR + GPT extract and summarize plaque text so users can focus on impressions, not typing.

Graph-based search (Neo4j) links buildings by architect, style, and visitor mood, powering serendipitous discovery.

Challenges we ran into

Data consistency – crowdsourced tags needed auto-merge logic to avoid “Frank Gehry / Gehry, Frank”.

On-site UX – tourists often lack signal; we cached drafts locally and synced once online.

Sustainability – hosting high-res photos threatened costs, so we adopted tiered image resolution and IPFS pinning.

Accomplishments that we're proud of

Conducted usability testing with practicing architects and architecture students; most praised the clean, intuitive UI and quick tagging workflow.

Prototype adheres to WCAG 2.2 AA accessibility guidelines and supports system dark-mode.

1 000+ sample building entries imported into our Neo4j graph with sub-second search performance in local tests.

What we learned

Community first – a tight, mission-aligned user group is more valuable than raw download numbers.

Frictionless capture matters – trimming the post flow to ~20 seconds doubled content volume in tests.

Structured metadata + narrative beats either alone for searchability and emotional resonance.

What's next for archhive(アーキハイブ)

Private beta with selected architects and schools, focusing on real-world workflow fit.

AR “lens” mode to overlay historical facts and user notes directly on buildings.

Pro tier for architects: analytics dashboard, portfolio export, and BIM integration.

City-heritage partnerships to crowdsource preservation data and virtual tours.
