for attackers who knows the benefit of homes, you should start at a minimum of 40%.. anything less than that doesnt really lifts up its bonuses.. there are a lot of home threads in past, just look for it..

but since the OP asked for a undead/warrior build, here's mine:

Pump Build (Normal stance / Non War)

Bank 20%
WT 20%
Guild 20%
TG 20%
Hospital 10%
Tower 5%
GS 3%
Dungeon 2%

War Build (Pre War / Hostile)

TG 20%
WT 10% against normal KD
20% against T/M or Hybrid heavy KD
Hosp 10%
Guild 8%
Tower 5%
GS 10%
20% against heavy attacker KD
Dungn 2%
Rax 15%
Bank 10%

If you're getting T/M chained : swap the banks for more WT
If you're getting deep chained : swap the Rax for more GS

* swap from incoming acres, easier if you receive some aid to raze and rebuild
