If you're buying the property, let me ask you this. Is there room in the future to build an addition to that space? You could do one room now (which I personally love to work in), and focus on making that room outstanding and intimate. Take advantage of the space to make the best room possible. Then later on, when you've made some money, reinvest into an additional control room if you decide that you want one. The only time I wish I had a dedicated control room is when sweeping a cab. Other than that, I don't miss the space I used to work out of. We had a really nice control room, and it always got in the way for a lot of things.
This is exactly what I would do. If you're even slightly experienced in construction work, it will be easier and cheaper than you might expect.
