Predator Control: Is very important and can mean the difference between safe, secure alpacas or a disaster that meets you at the barn...
Find out what predators may be present in your particular area. The only defence an alpaca has is to run...Some alpaca owners use guard dogs or guard llamas. Protective fencing is a must.
Farm Structors: Alpacas do not need a "fancy" structure. What they mostly need is a roof and 3 sides for shelter from rain, snow, cold winds, and hot humid days. Any alpaca owner will admit to the convenience of lots of gates...you can never have too many. Make sure gate latch is one that will close and latch easily.
