Check what the drawing belongs to
Ask whether the plan describes the exact unit, a typical layout or a proposed design. Look for a unit reference, floor and date or version if supplied. If a layout differs from the photos, ask which reflects the current home. Keep a typical plan clearly labelled; it cannot confirm that the advertised unit has the same doors, windows or finishes.
Ask what the stated area includes
Do not assume that two advertised square-metre figures use the same basis. Ask the advertiser what the area covers and which spaces are included. Keep the answer with the figure. A price-per-square-metre comparison is only interpretable when price, currency and the area basis are comparable. The website does not determine surveying standards or validate a measurement.
Trace everyday movement
Start at the entrance and follow a route to the kitchen, bathroom and bedrooms. Notice whether rooms require passing through another private room, where doors open and how storage fits. Imagine furniture of realistic dimensions rather than relying on decorative symbols. Check whether a desk, bed and wardrobe can coexist without blocking doors. Write down measurements you need to confirm.
Connect the plan with photos and a visit
Locate windows and balconies on the plan, then match them with the photos. Ask about orientation if it matters to you and observe actual daylight during a viewing. A drawn window does not establish the view or surrounding noise. Mark any room you cannot identify in the photographs and ask for a clearer image or to see it during the visit.
Keep missing dimensions visible
If there is no plan, ask for dimensions of the rooms and openings that affect your essentials. Use permitted measurements during a viewing to answer those questions. Record an approximate measurement as approximate. Compare homes using confirmed layout needs first, and postpone a fine-grained size ranking when the underlying information is missing.
- Exact or typical unit identified.
- Advertised area basis clarified.
- Important furniture and access measurements recorded.
- Windows and room photos matched.
- Unconfirmed dimensions kept as questions.
A practical case and next step
Suppose both adverts state the same area but one plan includes a large passage and the other provides the desk space you need. Ask about room dimensions and the area basis before declaring them equivalent. Use the layout against your essential activities. Do not turn an attractive furniture drawing into a confirmed measurement; keep dimensions that you have not checked visible.
