The Knowledge Tree

Roots feeding in.
Branches spreading out.
Every leaf verified.

One tree per discipline. One hub between them.

Each discipline grows in its own cardinal position — Civil west, Electrical north, Mechanical east. Their branches lean toward the centre where the shared body of knowledge sits. Hover any leaf to preview, click to open.

Shared body of knowledge

Cross-discipline hub

Each tree leans in. Future links between branches let an engineer climb across disciplines on the knowledge they already trust.

Growing next

Renewables tree, planted here.

Solar, wind, hydrogen, grid storage, heat pumps. Where Civil, Electrical and Mechanical converge — and where the next thirty years of engineering happens.

Verification tiers:
Tier 1 · General best practice
Tier 2 · Technical guidance
Tier 3 · Safety-critical
Built on the official spine

The tree maps to 522 occupations on the Skills England register — 466 with a published apprenticeship standard.

Engineering and manufacturing: 372 occupations (L2–L7) · Construction and the built environment: 150 occupations (L2–L7). The same government taxonomy underpins Pathways — so what you learn here counts on the same spine you climb there.

The vision

Climb the tree.
Move across disciplines
on the knowledge you trust.

The roots are the fundamentals — what every engineer learns. The trunk is the shared body of knowledge — concrete, electricity, thermodynamics, materials. The branches split into civil, electrical, mechanical and beyond.

Each leaf is verified by named, credentialed practitioners. A civil engineer can grip the branch into renewables knowing it's been tested. An electrician can move into building services knowing the path is marked. That's the tree.
