in your case you can use several different ways to talk about the future:

1. Present Continuous + time word:

I'm coming to your house today.

This form used to talk about plans which are already arranged for a particular time in the future. and it is used very often with come and go and with verbs like visit, meet, etc ...

2. BE + Going to:

I'm going to come to your house today.

Be going to can also be used to express the same idea; however, it puts an extra emphasis on the idea of intention.

3. Will:

I'll come to your house today.

This form used to talk about things that we decide to do now.

Note: At the moment of making a decision, use 'will'. Once you have made the decision, talk about it using 'going to'. and if it has arranged talk about it using 'Present Continuous + time word'
