I'm a bit late in this forum but I just want to share what I've essentially done for Sulani in almost all of my casual saves. I kept all of the pre-made lots, but added my own twist with LittleMsSam's live-in business mod. It made sense to me that the Sulani townsfolks are self-sustaining, so all of them have a type of business in their house instead of building new modern ones:
1. The chieftain's villa is now a live-in daycare and a cultural center, where during daytime toddlers will be sent there because their parents are away at work. The cultural center thing is basically an open air library/museum/tattoo place where new young adults will get their tats ceremoniously done by Keala or Lia.
2. The kin-ship also functions as a bar and gathering place, so anyone can get tips and learn from Makoa himself on how to best preserve the island or about sailing. There's also a mic and guitar for both Duane and Nani to show off their skills, lol.
3. The lagoon look is a family restaurant instead of a house; like, what kind of town doesn't have at least one place serving up local dishes to tourists? The location (next to the beach) was also a deal-breaker for me, because people usually get hungry after a few hours of playing sand.
4. Tangled Flat as a motel! with the creepy crawlies and haunted traits! and some tombstones to really get the groove going. That's where my non-sulani sims sleep in during their visit to the island.
5. the beaches and sand bar are still the same, except the bar is actually a night club.
6. The Kahananuis, being ambitious entrepeneurs, own a live-in shop where they sell woodcrafts and some beach clothing. I have no other explanation other than their home has the 'rich and culturally fashionable' feel to it.
7. The Ngatas own a gym in their house. People come in to get ripped and shower in the open air. fun times.
8. The Pier Perfection is home to my sulani sims, which is also a live-in nightclub during nighttime.
9. Sand Simoleon Beach is now Sand Simoleon Spa; I renovated this lot the most, adding massge beds, chairs, sauna, and places for zenness in overall.
10. The Saphhire shore is a wedding park in one save, and an empty beach in the rest. I just don't know what to do with it.
11. Caldera camp is home for some npc sims which I forced to be vets. I added a basement for their basic furnitures and used the whole ground floor as a run-down vet clinic area, where sick pets go - even the wild ones :wink:
12. Key point is now known as Obsidian Splay thanks to the latest live build objects cheat. I built a steven universe house there but never really bothered to live in it :lol:
