The future is build up with the auxiliary verb “werden”. It takes the place of the main verb and the main verb is put at the end of the sentence.
"Werden" is a irregular verb: ich werde / du wirst / er wird / wir werden / ihr werdet / sie werden
In my original answer to this question I typed Hause. When I checked the answer I was told my answer was incorrect. I should have typed Hauser When the question was repeated and I resubmited my answer I changed my answer to Hauser and was informed that it should be Hause. Please explain.
