We built a 1,600 sq ft 80 seat combination black box theater and dance studio about 10 years ago. Before and after photos below as well as a production photo from a summer production of a workshop of a new musical based on Midsummer Night's Dream.
I believe the budget for fit-up of the room (including some required fire marshall alterations was about $20,000 Thet included the cost of adding a mezzanine for use as a light/sound booth and green room. Sound and lighting gear was sourced mostly from eBay and cost about $8,000. We have staged everything from full musicals to cabaret-style performances (think 54 Below). In our case, we also had to spend about another $15,000 for mirrors and a sprung floor.
The approach I'd take is to first assess what limitations the space, when finished, will enforce on you. That should help define just how ambitious a project you could undertake. For example, if the finished height of the space can't be at least 15 feet or so, it's going to be challenging to hang a decent lighting plot. If the dimensions are such that it's going to be less square and more broad yet shallow, you will have little flexibility in staging and audience placement.
If you live near someplace where there's a USITT member school, IATSE Local presence or good theatrical supply house, you will be able to find someone that might be willing to provide some advice specific to your situation. The best source would be a member of
American Society of Theater Consultants but depending on your potential budget and scope is probably unreasonable. Be cautious about relying on conventional school architects alone as they often have limited knowledge. If they can't tell you why a black box should be flat black rather than semigloss, that's a good barometer.
Hope this helps a little!

Subject: Costs for building a black box theatre
Folks: I'm in a rural community where the high school auditorium is the only place in town for events. A bond was just passed that will add on an extension to the school. While the new building is probably designated for the Ag. Sciences, I'd like to create a proposal for converting old classrooms into a black box theatre. Has anyone done this in their district? Even if you haven't, any insight into how I could go about this is appreciated since my tech background is pretty limited. Thanks!
