Asalamualaikum, in jannah we can have whatever we desire as long as its not haraam. So in jannah can someone have their own custom world to live in and regards to our spousethey will be as how we want them? In Quran Allaah describes the hoor al ayn so I was wondering if this means all look the same

In Jannah a person is given whatever his soul desires and his eye delights in, for Allah says, the meaning of which is: therein is whatever the souls desire and the eyes delight in (al-Zukhruf 71), and: they will have therein whatever they wish (Qaf 35). So the believer is given of joy, and of spouses, what pleases him in the most complete way. As for the reality of the hoor al ayn and the details of that bliss, none knows it except the One who created it, for it is what no eye has seen, nor ear heard, nor has it crossed the heart of any human (agreed upon). We believe in what came in the texts without delving into how, and whatever you imagine does not come close to it.
