I just ran into this problem too. I gave my female a new larger house because she is big and could not fit into her igloo. I had a small rabbit club house that came with the marchioro cage. She loves it. And I can lift the roof off and watch her sleep. 
So I decided to buy a second house for my male. He hates it. He has abandoned the new house and wedged himself under the cage liner. Even when I added more fleeces inside his huse he went back under the liner.
He is a very small boy so I am going to give him back his igloo tonight. Maybe when he is bigger he will feel more cozy in the larger house.
