The most proper translation is:
Cuantos cuartos tiene su casa (How many rooms does yours house have)
Though the following is also okay:
Cuantos cuartos hay en su casa (How many rooms are there in your house)
Replace "su" with "tu" to make the statement informal
Cuantas personas viven en tu casa?
"Mi hogar" is "my home" in Spanish.
cuantas habitaciones hay en mi casa
¿Cuántas personas viven en tu casa?
You can say "La casa tiene seis cuartos"
Los cuartos en una casa.
That is Spanish for "How many rooms does it have?"
cuartos
tá (number) sheomra i mo theach
Impossible to say without knowing how many rooms and what size they are.
house = casa
el casa = a house
'in-house' - interior, interno/a
"hen house" translates to, "gallinero" in Spanish.
La casa de muchas puertas.
en la casa del mayordomo is the spanish for at the butler's house
