Stephen's Harvest Moon/Story of Seasons Challenge

I'm not sure I fully understand the Expansion Requirements. There is a lot of information written maybe too concisely. Let me see if I understand what it means. So for House Upgrade 1, I will need to have at least 4k in the bank and have completed any one upgrade already. And that required upgrade could be, for example, building a second field after having 100% excellent crops in my first field? And to complete House Upgrade 1 I need to spend 4k-6k on separating the kitchen from the the bedroom, upgrading furniture and increasing the house size to 64 tiles?
