Punctuation for consecutive questions

[Hiperbólico]

How does one punctuate two back-to-back questions in Spanish? (that is, if I don't want to simply combine them). For example...

—¿Dónde está? ¿Está en tu casa?

Or do I write it another way? Thank you.

It's perfect. I can't imagine a better option.

I agree with Julvenzor, but you can also use a comma to have both questions inside one pair of question marks:

—¿Dónde está, en tu casa? (Notice that the second "está" has been ellided so both questions can go together.)

Awesome, and I would assume the same applies for ¡...! sentences. :) Muchísimas gracias a los dos.
