I want to build a studio on my property. Not an addition to my house but a seperate, nearby structure. My main concern is soundproofing so my neighbors do not hear the band (rock, loud) whatsoever. Other than pouring the concrete foundation, I plan on doing all the work myself (framing, plumbing, electrical, etc) . I'm trying to figure out the best way to create soundproof walls, windows, ventilation, etc. Any advice as to which soundproofing method works best or where I might find detailed construction information?
