For this build, you will want to back as soon as you get 1,000 gold so you can get Survivor Sash. You are building Eye of Erebus first item, but if you decide to use Lifebinder instead, start Gem and 3 Health Potions.
This depends on playstyle, but overall Eye of Erebus is more useful throughout the game in my opinion.
Build Breastplate of Valor here instead if the enemy team is primarily physical, not just if your lane opponent is physical.
