Building a new home, mostly studio, where to start?

Hi, I'm Daniel Lewis in Bangor Maine, I've been recording for 2o years or so, the last 15 as a small studio business and I need to relocate :( I have been in the research stage the last 2 months or so, and wow! My eyes are blurred from reading these pages, so I'll get right to it. I am looking to build a home with a small loft, the studio being the important thing, in fact the whole downstairs can be studio. I already have the land, I think I'll be 150 feet from my nearest neighbor. I do not have alot to spend.$90K- $125k to start,but if I do it right from the start can I not finish rooms as money allows? I can do grunt work but do not have construction or design skills I will leave that to others. I would like a separate control room,drum/performance area a guitar closet,and bathroom, all downstairs. I think this is the minimum I would want to open with. I've been looking at 28*40 post and beam style with a 12*28 loft, with a cathedral ceiling over the rest of the space. I'll go with whichever demensions work best. I have looked at cape style log homes made from cedar or post and beam, with hemlock 4*4's and 4*6's the style of home is not important to me, so before I start can you give me opinions about: Is cedar better or worse than other materials? Is a log home a bad idea? How about the loft for the bedroom and the cathedral ceiling for the drum room? I was going to put this on a slab, better than a cellar? Which demensions should I start with? Thanks for any help! daniel
