What it is Filled
Furniture and fixtures are the movable and fitted objects that furnish a space for use: chairs, tables, beds, shelving, cabinets, fitted kitchens, sanitary fittings and built-in units. Furniture can be moved without damage, while fixtures are attached to the building and usually pass with it; the building fabric and its technical systems are separate subjects.
Why it exists Filled
Movable furniture and fitted fixtures that furnish a space, with safety and placement.
Distinguishing features Filled
- Furniture is movable without damage, while fixtures are attached and usually transfer with the building.
- It furnishes a space for human use, unlike equipment and machinery that perform a technical process.
- Each object is a physical instance of a product type that may be recalled.
- Distinct from building elements such as walls and doors, which belong to the fabric.
What robots and AI may and may not do Filled
Must not
- Climb on, stand on or overload furniture.
- Remove fixtures attached to building services such as water or electricity.
- Dispose of objects without the owner's approval.
- Block escape routes or accessible paths with furniture.
Only with a human decision
- Removing or installing fixtures connected to building services.
- Disposing of or selling furniture assets.
- Deciding whether a damaged item is safe to keep in use.
May
- Inventory furniture and fixtures with location and condition.
- Check models against product recall lists.
- Plan layouts that respect clearances and accessibility.
- Move or handle light furniture when the robot is rated for the load.
Moral aspects Filled
- Tip-over and collapse injuries fall mostly on children and older people.
- Accessible furniture and layouts decide whether disabled people can use a space.
- Reuse and repair reduce waste compared with replacement.
Who is affected
- Occupants and users of the space
- Children and older people at risk of injury
- Owners and facility managers
Owners Filled
Steward
The owner or facility manager of the space, who answers for the inventory, safety and disposal of its furnishings.
Master systems
- Facility asset register
- Computer-aided facility management system
- Product recall database

What else AI and robots need to interact with it Filled
Identity and identifiers required Filled
- An object is identified by an asset tag in the facility register and by the manufacturer's model and serial number where present.
- In building models furnishing elements carry IFC GlobalIds.
Direct properties required Filled
- Overall dimensions in millimetres: width, depth and height.
- Mass in kilograms and rated load in kilograms or newtons.
- Seat and work surface heights in millimetres for ergonomic and accessibility checks.
- Fire behaviour classification of upholstery and materials under the applicable test standard.
- Fixing method and anchoring points for fixed and tall units.
Recognition required Filled
- Recognised by shape, size and position in a room from images or point clouds.
- Fixtures are often confused with building elements, and stacked or covered items are easily miscounted.
Capabilities and actions required Filled
- Furniture can be moved, reconfigured, repaired and reused.
- Some objects have adjustable or powered parts such as height-adjustable desks or beds.
Hazards and failure modes required Filled
- Tip-over of tall or unsecured furniture.
- Collapse under overload.
- Pinch points in moving parts and fire spread through upholstery.
Standards and interfaces required Filled
- ISO 16739 Industry Foundation Classes furnishing elements in building information models.
- Asset registers and facility management systems exchange inventory records.
- Product recall notices from safety authorities.
Context of use required Filled
- Found in homes, offices, schools, hospitals and public buildings.
- Subject to product safety law and, in workplaces, ergonomics rules.
