to make a spawn, lobby, or an arena?If answered yes, read this forum and in seconds you'll be the best builder on that server!
One first thing to start with is the shape, size, and color. It depends on what you like best for the color (My favorite is spruce planks) and then it also depends if you like Art Deco (I prefer spheres) for the shape. Then if you need to fit a lot of information then you should do one of the two, 1. Make it bigger. 2. Put in less furnishing.
Next to do is the floor. To make it have a detailed look vary in types or variants (EX. Chiseled Stone Bricks, Stone Bricks, Quartz, Chiseled Quartz, etc...) And then give it a pattern and make sure it is symmetrical, because symmetrical is key.
Next thing to do, or as I say shouldn't do. Some people when they build structures use a ton of glass, but for some structures with quartz and, or iron blocks can have a lot of glass. So don't use to much of glass if you build the structure like mine.
Next modification to do it to make the walls curve in or out to give it a wavy look (Try to use the main source that you got the block your building it with (EX. Spruce Planks = Spruce Wood, Wooden Planks = Wood, Cobblestone = Stone, Stone = Cobblestone, etc...)
Now, for the hole that you might of left you should put a transparent block, curving down, then leave a 3 by 3 hole in the middle. Then put 1 quarts block in the middle of the 3 by 3 hole (Not included in picture).
Next we are going to add a water feature (optional). The spot where we left the 3 by 3 hole is going to be where it will be. Next you should make the path of where the water will flow, it cannot go on the ground. Then you will place the water of where the glass starts ONLY on the sides.
Now you need to add furnishing. If you are making a spawn, you don't need much furnishing you only need posts to place signs and other stuff for it. And if you are making a house or something else you will probably need chairs, tables, TV, crafting table, etc...
