You just have to imagine further, what if it were better, they were smarter, and so on. Due to ecological concerns maybe the only legal construction robots will build shelters with locally sourced materials that are biodegradable and so on, so shelters will resemble those of our ancestors more. Maybe robots will come by and repair things every so often to make up for less structural integrity. Or maybe the construction techniques will just be so much better that the local materials like mud will end up being as strong as concrete. I know it's pie in the sky but for for the implications of a super intelligence we have to just flex our imagination as much as possible since they will be ridiculously 'smart'.
