The portal building I improvised. The building is two-story. There are 15 portals on the first floor. I decorated the upper floor completely for visitors to your world. Visitors to your world can eat on the upper floor, take food and potions to their inventory. They can rest. They can use the bed to spawn points. They can equip armor and weapons. They can repair at the workbenches, all of which are top-level. You can enjoy the view on the balcony at the back and open the map of your world using the cartography table. I hope it was useful. Enjoy it🙏
