I was aware these huts were out there but never had seen them with minis to add scale. Very impressive, perfect compliments to your most excellent Lost World!
I'm curious about who will be inhabiting these imposing domiciles: Pulp Figures'
Lost World & Lost Tribes range immediately comes to mind, or their Melanesian Island Warriors in the
Savage Seas: South Pacific Adventures range. Plus the lady on the right, below, left as a tribal sacrifice to the T-rexs, perhaps? The ladies are found in the
Weird Menace range.

But there are certainly more choices for your Lost World natives. Keep us informed with your progress!
I freely admit that at my advanced age, whether or not a terrain piece needs painting and/or assembly is the first and most important factor when making a purchase. That makes all the Battlefield-in-a-Box terrain pieces mighty attractive.

You might want to pick up a set of their Rocky Outcrops, shown below, before they go out of print (like so many of their earlier--and very nice--offerings).
