I have 2 buckets for my Primary, 7 glass carboys for secondary and a 6.5 that has a Ed Wort Alpha going in it. My space is limited as the wife keeps reminding me.
If you end up brewing everyweek, you can build up a stockpile. Due to my job I was only able to drink on brew day with my brewing buddy and after months I ended up building a stockpile of 21 cases. With some time off due to me that has shrunk to 14 cases, but with two due to be bottled, this weekend it will grow once again.
