Hi Linie and sfpugh,
Thank you for your question. Sfpugh is right, wollen is a modal verb. Other German modal verbs are können, dürfen, sollen, müssen and mögen.
Whenever there is a sentence with a modal verb and an infinitive (machen in this case), the infinitive is always placed at the end of the sentence or clause.
Let me give you some more examples:
"Ich will heute Nudeln essen." - "I want to eat pasta today."
"Er kann das Deutsch sprechen." -"He can speak German."
"Sie muss das machen." - "She has to do that."
You can learn more about German word order and modal verbs in lesson 7.6 Word Order Rules, lesson 6.8 Helping Verbs: KÖNNEN and SOLLEN and lesson 6.9 Helping Verbs: MÜSSEN and DÜRFEN.
