You are going to need professional help with this. You might be able to come up with the designs, but you will need an electrician and HVAC company to do climate control for you. This guy has several videos detailing his grow warehouse. Spend several days watching the last 18 videos he has put up if not all of his videos.

Building out a 16,000 square foot space is going to cost BIG MONEY. You could fit over three hundred 1000 watt lights in there. 300 lights is going to run you over 600$ a day in electric. If you set it up right, the lights will heat the entire building even in sub zero winter days, but you will want to have a furnace big enough to heat the entire building to at least 55 degrees in case of a power outage. If you plant to run all this during summer, you will need 50-70 tons of air conditioning depending where you are. We are talking 2 or 3 of these units with many many heads in the building.

Total build out would be about a million dollars I'm betting. That being said, you could be pulling 3,000+ pounds a year out of a facility like that and literally seeing profit by the end of the first year of operation.
My number of lights is based on having lights for half the facility, leaving room for walkways in each room, a drying/processing room, and just a general amount of space to work. Renfro's plan builds it out as all grow rooms with a 5 foot walk way going to each on. No processing/drying/office/break room/extra space for anything which is fine if you plan to build an additional building for that stuff.
