IN every house you have "language" params.
You may show 1 house for both languages, so fields names will show on site language, but field values - how user added.
Or you may set to house "language" params, so language as you need, and connect(associate) This house to another house under another language.
Or you may install component like SefTranslate (
ordasoft.com/sef-translate-joomla-translation-component) for automatically joomla site translate.
