idk where to go from here

My friends that have no idea how to build and have zero creativity so they tasked me with building them an npc hotel and this is where im at rn. I finished that first section and now theyre asking me to work on the section on the top like sort of a storage room for them. I have no idea how to make that work without making the whole building look like one copy-paste stone brick wall room. (Oh and by the way i havent finished adding furniture or decorating the bottom section 100% just yet and i dont rly know what to do with the leafy area in the middle, around which im planning to place a pylon. That relic is only a placeholder).

Any ideas/suggestions are welcome and constructive criticism is accepted so feel free to speak your mind about this everybody
