Updated September 2026. Marketing floor plans are useful orientation tools, but dimensions, approved use and structural feasibility should be verified before a purchase or renovation.
Start with scale and orientation
Confirm the scale, north point, unit entrance and the relationship between the unit and its surroundings. Read written dimensions before estimating from the drawing, and check whether measurements refer to internal spaces, structural lines or strata boundaries.
Read the symbols as a system
- Trace doors and their swing arcs to identify circulation conflicts.
- Locate windows, ventilation openings and likely daylight paths.
- Distinguish walls, columns, service risers, ducts and structural elements.
- Note ceiling drops, voids, balconies, planters and roof terraces.
- Map sanitary fittings, wet areas and kitchen services before considering layout changes.
Test the home against daily life
Place furniture to scale, preserve walking routes and test storage, work, dining and laundry needs. A room label does not prove that the space fits the household's furniture or routines.
Verify what the plan does not prove
SLA explains that Strata Certified Plans record strata-lot boundaries and can show floor and void areas for multi-storey strata lots. Owners can review title and plan information through official services, while buyers should obtain the relevant records and professional advice. Start with the SLA survey maps and plans guidance. Structural, planning and building approvals must be checked separately before altering walls or services.
This guide is general information. Use the actual unit, approved records and the appropriate Qualified Person for a binding assessment.
