What it is Filled
An exterior side of a building or structure, especially the principal front or facade, together with its surface, openings and architectural treatment.
Why it exists Filled
Let an agent describe building faces and facades by orientation, materials, openings, performance and heritage status.
Distinguishing features Filled
- An external side, not an interior wall
- Carries architectural identity and planning significance
- Must meet fire, weather and energy requirements
- The geometric face is a different entry
What robots and AI may and may not do Filled
Must not
- Fit or recommend combustible cladding where the rules forbid it.
- Leave loose masonry or glass above a public walkway without a cordon.
- Alter a protected historic facade without consent from the heritage authority.
Only with a human decision
- Deciding that a facade is unsafe and closing the area beneath it.
May
- Inspect and report damage, loose elements or water ingress on a facade it is authorized to inspect.
- Record a facade's materials and fire performance from building documents.
Moral aspects Filled
- Facade fires have killed many residents who trusted that their building was safe.
- Facades are part of the shared streetscape and heritage.
Who is affected
- Residents
- Passers-by
- Firefighters
Owners Filled
Steward
The building owner; building control and heritage authorities regulate changes.

- Wikidata: Q1959882 (https://www.wikidata.org/wiki/Q1959882)
Direct properties required Filled
- thermal transmittance: 0.1-3 W/m2K - glazing and walls differ
- glazing ratio: 10-90 percent
Recognition required Filled
- The side facing a street or approach, often the most decorated
- Orientation: north, south, east or west face
- Cladding, curtain walls and masonry are visible types
- The outward face of a building with walls, windows, doors, cornices and decorative elements; modern facades may be glass curtain walls or cladding systems.
Capabilities and actions required Filled
- design and build it
- inspect and maintain it, including for falling-object risk
- alter it, subject to planning and heritage rules
- clean, repaint or reclad it
Hazards and failure modes required Filled
- Combustible cladding spreading fire
- Falling masonry or glass
- Water ingress and damp
- Heat loss and overheating
Standards and interfaces required Filled
- Building codes on external wall fire performance
- EN 13830 curtain walling
- Heritage protection law for listed facades
- Facade inspection ordinances in some cities
Context of use required Filled
- Enclosing and presenting a building to its surroundings, admitting light and resisting weather.
- principal facade and secondary elevations
- masonry, rendered, timber, stone facades
- curtain walls and rainscreen cladding
- historic facades retained in redevelopment
Sources Filled
