The exposé states one living area, the plan gives a different area total. In addition there are sloping ceilings and a large balcony. At the same time you want to know whether your workplace and the existing furniture will fit. For the purchase decision you need two outcomes: a professionally explained area figure and a floor plan that functions independently of that. A single large number does not yet provide both.
Keep every figure with its reference
Our editorial recommendation: Assign the information from the listing, plan, calculation and draft respectively to the designated object and room extent. Note which type of area and which calculation basis are stated. Do not hastily label an unresolved total yourself as living area (Wohnfläche).
Ask for the underlying calculation including its plan status. An illustrated floor plan can show the furniture without already being a reliable area verification. If figures contradict one another, keep both versions and have the cause clarified.
Clarify the method to be applied before the calculation
§1 WoFlV states its statutory scope of application for calculation under the Wohnraumförderungsgesetz. [METHODE-ANWENDUNG] From this no automatic application to every private apartment purchase should be inferred. Have the basis relevant to your transaction determined by an expert.
If a calculation according to WoFlV is to be assessed, the associated floor areas according to §2 and the determination according to §3 are first considered. Afterwards the allocation according to §4 follows. [FLAECHENUMFANG] [MESSGRUNDLAGE] [ANRECHNUNG] The sequence is important: not every measured floor area will automatically be treated as living area to the same extent.
Check the items that can change the total
Within the WoFlV framework allocations depend, among other things, on room height and type of area. Balconies and the other external areas named in §4 no. 4 are regularly credited at one quarter, at most at one half. [ANRECHNUNG] A large external area can therefore appear differently in different sets of figures without its legal or technical classification yet being resolved.
Pure calculation example: If an exclusively assigned balcony floor area of twelve square metres were credited at one quarter in an appropriate WoFlV case, the result would be three square metres. The example does not confirm either applicability or the correct approach for your balcony. It explains why the floor area and the credited portion are different figures.
Give a clear inspection mandate where decisive doubts exist: which rooms and areas are to be checked according to which basis, and does the existing drawing match the executed state? This article is not an instruction for conducting your own evidential measurement.
Test your furnishings independently of the total area
A correctly calculated area can still be inconvenient for your everyday life. Draw the important furniture with actual dimensions into a suitable current plan. Take into account doors, accesses and the movement areas you require. A sloping ceiling can limit a particular standing height even if part of the area is credited.
Check the purchase‑decisive dimensions at an agreed appointment or have them checked. A symbolic furnishing from the sales material will not be accepted as confirmation of appropriate measurements. Legal area calculation and practical usability remain separate results until the final comparison.
Hypothetical case: favourable price per square metre, unresolved basis
A buyer compares two offers on the basis of the purchase price per stated square metre. In one offer apparently a larger mixed total was used. At the same time the planned wardrobe does not fit on the wall intended for it. The arithmetically favourable figure solves neither the area question nor her furnishing problem.
She has the calculation bases clarified and then tests the same everyday tasks in both flats. Only on a comparable basis is the price comparison updated. The example does not state any market‑typical price and does not establish any specific area deviation.
Clarify the property that is essential for you in the contract
§434 BGB provides the framework for examining subjective and objective requirements of the thing sold. [BESCHAFFENHEIT] What significance a concrete area figure has in your property contract must be assessed in the light of all relevant declarations. This article does not specify a blanket tolerance limit, an automatic price reduction or a promise of rescission.
Submit the clarified calculation and any remaining contradictions to the contractual advice before becoming bound. The result should make both the significance of the area figure and your actually checked floor plan recognisable.
