The only mistake you made is that you said ために instead of ための. The correct sentence is:
それのための場所がありません。
ために is adverbial (modifies a verb) and ための is adjectival (modifies a noun). Obviously you want それのため to modify 場所 (noun) right after it, so you should use の.
See:
- Why can we use の after へ and から?Why can we use の after へ and から?
- using の with と,で, から, までusing の with と,で, から, まで
In addition, それのため is a bit wordy; you can simply say そのため.
そのための場所がありません。
If you want to explicitly say "enough", use 十分 (na-adjective):
そのための十分な場所がありません。
P.S. You don't have to apologize for making an incorrect sentence, but we don't do general proofreading. Next time please specify the grammatical point you are most concerned about.
