Best Project Zomboid Base Layout
A "best layout" depends on whether you're running default sandbox, Apocalypse, or the harder mods, but four principles hold across all of them: corner placement, double walls on the threat side, generator coverage, and a single funnel you can defend.
Corner placement
Picking a structure with two outside walls flush against the map edge eliminates two attack faces. The classic example is a corner house in Muldraugh on the north or west side of town, but rural cabins on the map border work too.
Double walls on the threat side
Zombies attack the closest tile. Two metal sheet walls back-to-back double the time-to-breach without doubling resource cost — the second wall doesn't take damage until the first falls, and you can rebuild the outer one between waves while the inner one holds.
Generator coverage
A standard generator covers roughly a 20-tile radius. Drop it outside, unroofed (or on a balcony) so you don't poison yourself, but near enough to power the fridge bank and base lights.
Kill funnel
Leave exactly one entry point. A sheet-roped second-floor window plus a single barricaded door means zombies pile at one tile — you fight them one at a time instead of being surrounded.
