Key legal question
Whether exchange entitlement applies to an invalidity-related bathroom adaptation carried out in a new extension instead of the existing bathroom.
Extracted holding
Yes. The insured person may claim a contribution based on the cost of adapting the existing bathroom, even if he chose a new construction solution that functionally replaced it.
Extracted reasoning
The court held that the relevant rule on invalidity-related structural adaptations covers adapting bathrooms to disability. Administrative instructions narrowing exchange entitlement to rooms located inside the existing building were inconsistent with the law and could not lawfully restrict the statutory and regulatory entitlement. The chosen solution was practical and served the same function as the admissible adaptation.
