All the houses in that little development all share the same master plan. If they bought there, Meri was getting a big house. They could, however, have chosen a different development where there was some variety in house size. They were limited further by their ability to get mortgages and they were able to get the large houses most of the women needed with interest only loans initially in the development where they bought. So Meri got a big house and pushed it further with the wet bar option.
