euer is used with masculine and neuter nouns, e.g. euer Löffel und euer Messer "your spoon and your knife" (der Löffel is masculine, das Messer is neuter).
eure is used with feminine nouns as well as with all plural nouns, e.g. eure Gabel und eure Teller "your fork and your plates" (die Gabel is feminine; Teller here is plural).
Haus is neuter (das Haus) and so the correct form is euer.
In the plural, it would of course be eure Häuser because eure is the form used with plural nouns.
diene means "am serving" and would be completely inappropriate here.
deine with -e would be "your" before a feminine or a plural noun.
Haus is neither of those: it's neuter.
So "your house" is dein Haus when it belongs to one person, euer Haus when it belongs to several people.
