Translation:It is broken. It was not hard enough.
I'm curious. I can't find a meaning for ard, although there are lots for àrd, but none seem to go with chruaidh, except maybe High Hard? I'm from the US, where we don't name our houses (we only use efficient, but very boring, numbers and streets). I do know that house names can be somewhat idiomatic, so I may be missing something on Ard Chruaidh. Can you enlighten me as to the meaning? Tapadh leibh, a charaid!
