This cute little beach cabin is only 30 land impact and has a base area of 6x9. It's a one-room house with that little bit of front verandah to watch the waves.
I've also included all the decors and plants, even the little parakeet perched on that lantern post. The landscaping and decors adds another 13 land impact.
The Lulu Beach Cabin is available for 99L at my in-world store and the Marketplace. Please see the demo at my in-world store.
