In the final episode of Seeking Sister Wife‘s first season, the Briney family is getting ready to move out of state, but there was a difference in point of view about whether all the wives should continue to live together or not. In the final scenes Auralee is an absolute saint. She extends the olive branch in an amazing way to her sister wife, April. Angela chimes in as well, and they all end up coming together in a beautiful way for the good of the family in both practical and emotional ways.
As may be expected, working out where everyone lives is a very common dilemma facing plural families, and it can be handled in a variety of ways. Some families live in a single dwelling, sharing the same kitchen and living room (like the Alldredges do). Some families may live in a single dwelling with separate apartments like my house or like the Fosters or Morrisons. Some families have separate houses for the wives, but they are all in close proximity to one another, on the same property (or in the same cul-de-sac, like the Brown family currently does). Some families may have separate houses for each wife, and those houses may be in separate cities or states. I even know one family where the wives are in separate countries halfway around the world from each other (although they are working toward living all together).
Furthermore, many plural families are somewhere in between these various solutions, 
or in transition between them. For example, I know a family with three wives. Two of them lived together in a single dwelling while the third (who was reportedly more difficult to live with) lived in a separate city. Later on, the third, separate-city wife moved to a separate house next door to the other two, and lived there for a while. Now they are all living together under one roof! Ultimately, the solution to this problem will be different for each family, and lies in finding the correct balance between the practical and the emotional. Both are very real issues, and need to be addressed.
The practical side of the question deals with resources like time and expense. It is certainly more expensive to live apart: There are multiple rents or mortgages to pay, separate utility bills will add up to greater expense than a combined bill, more property taxes, more home insurance, more time and expense for home maintenance, added expense for owning duplicates of many items, and additional time and expense is involved in travel between homes. These, and a great many other things, are practical factors that must be considered. I think a general consideration of practical factors will favor living together.
The emotional side of the question deals with feelings, perceptions, and jealousies. Some wives may not be able to stand seeing their husband show affection for another wife, may not be able to abide sharing a kitchen or other living areas, or may have or want different rules for their children. Kody Brown once said, “I have two wives who think sharing a kitchen is abusive”. This is in contrast to the Darger family whose philosophy is: If you can’t share a kitchen, what business do you have sharing a husband? Of course, the Dargers are somewhat of a special case as the wives are already close relatives (which I am sure has been a blessing to their family). I mean, how different could their kitchen management styles be? They all have the same grandma. They probably all have the same book of family recipes.
One plural wife I spoke with told me it can be harder to share a kitchen than to share a husband. So, if you are adding an extra master bedroom to your house to accommodate a new sister wife, you may want to consider adding another kitchen too. Each family will have to find what works best for them.
Children further complicate emotional considerations. Children from different wives may have rivalries (especially if they are from previous marriages) or resentments. In addition, there may be worries about societal perceptions. (What will the neighbors think? What will my friends think? What will our extended families think?) Finally, some people may just be plain old difficult to live with — there are personality conflicts of all kinds. These, and a great many other things, are emotional factors that must be given consideration. I think a general consideration of emotional factors will favor living apart.
From my point of view, I think most (perhaps all) polygamist men want to have their families together as much and as close as possible. If a plural family is not living together, it is very often because of difficulties between wives, or children from different wives (think of Sarah and Hagar, and Isaac and Ishmael, for example). I was once talking with my grandpa about the scriptures when the subject of Abraham’s wives came up. He said it was a shame that Abraham had married Hagar (because it led to difficulties that separated his family) and that he shouldn’t have done it in the first place. I told him the shame was not that they married, but that they didn’t stay together and try to work out their problems. Well, I’m not trying to pass any judgment on Abram, or his views on marriage and family, but I do think it is generally better to work on problems while problems can be worked on – even if some separation is warranted while the problems are being resolved (it may take years in some cases). Anything worth having is worth working for.
Why would plural husbands generally want their family together? There are certainly the financial pieces, which I mentioned above, and this weighs heavily on most husbands’ minds. In addition, a husband will be able to more effectively portion his time between the members of his family and his other household duties. Another important factor is the way that close-living facilitates family activities, family teaching, and family worship. Finally, there is a desire among men, even if subconscious, to have their wives and children close for the sake of protecting them. If a family can make it work, there are so many benefits to living together!
From a Biblical perspective, during the time when a couple was engaged to be married, the bridegroom would go away for a time and busy himself preparing a home for his new bride to live in. If the man had more than one wife, he would have prepared a home for each of them in turn. The home(s) would be built on the ancestral lands of the bridegroom’s father. The bride-to-be fully expected to receive her own home to live in (whether this was a separate dwelling, or an extension of the existing family dwelling, would depend on the particular family and circumstance), and providing one for her was part of the future husband’s duties toward her. When the home was made ready, the bridegroom would return for his bride, receive her to himself, and lead her to her new home which would become her responsibility to tend and care for.
In my Father’s house are many mansions; if it were not so, I would have told you; for I go to prepare a place for you. And if I go and prepare a place for you, I come again, and will receive you unto myself; that where I am, there ye may be also. – John 14:2,3
Speaking of Polygamy... 
I enjoyed reading this. Especially the end part were you mention how it was in biblical times.
