    Architect's conclusion

    Damien Hublet — Architect

    "The house is in its original state, unmodernised apart from the roof. It is only viable through substantial renovation or transformation, or even demolition and reconstruction. On the positive side: the location near Luxembourg City in a quiet rural area. Potential exists, through a major transformation project."

    What this report would have enabled

    Negotiate with hard facts

    With €635,000 in identified works, the buyer has a powerful negotiation lever on the sale price.

    Avoid a costly surprise

    The non-compliant electrical installation alone could have cost €15,000-25,000 to bring up to code after purchase.

    Make an informed decision

    Buying this house means a reconstruction project. The report lets you know that before — not after.
