What is the ruling on a married man marrying his maternal aunt's daughter, who is a virgin, while they both reside in the same house due to his inability to provide a separate dwelling for the new wife?

An independent dwelling is a right for the wife, and if she does not waive it, then it is forbidden for the husband to house her with her co-wife, unless both wives agree to it. Housing them in one dwelling without their consent leads to disputes and disrupts marital harmony.
