Unfortunately taking much longer time to build our house than originally planed. Just notice there is an expiration date on the house plan. If the house does not get done within, does any one know what we need to do ?

Assuming it's your Building Permit that has an expiry date (ours was 1 year) providing you start before that date I don't believe there is an issue.

Even if you let it expire (our did due to financial problems) it's a simple matter to get it re-done.

Of course, things may differ in your area so YMMV.

Thank you for respond and yes, it's our bouilding permit.

Did you mean "Re-done" as do apply it again ?

Yes ^^^, ours expired, but since it had already been approved once five minutes (and 1000 Baht) got it re-certified for another year.

The man just added a new stamp and signature to the existing permit.
