need help building a vocal booth...please help. thanx

my dad is a construction worker(builds houses) he said he would build me a vocal booth in my room... but he needs to know what type of wood and materials he will need for the booth...? the booth will be for vocals only. my studio room is on the basement floor..(3 floor house) it's pretty quiet around my room...(no loud cars,planes,streets,ect.) but the problem is that my parents rent to a family on the 3rd floor. and I dont want to disturb my parents or the family living on the 3rd. a place where whoever recording can record lyrics with full power without lowering his voice because of noise pollution problems.. the music I have produced will be played through head phones. the booth will be in a room (dead space) and it is planned to have a window and a door. one person sized vocal booth if you could help me out...that would be awsome! so I could read over the details of what we need. letting my pop's know what's up and getting the booth building rolling.... 1: what is the best wood to use when building a vocal booth? 2: what type of sound proofing materials will I need for the inside and outside of the booth? if anyone has any plans or links to vocal booth plans...that would be much loved also. (my dad loves plans) I have looked everywhere...but all I find is studio plans... thanx. take care!

Hi: I think it would be advisable to read the 'stickies', and 'before you post' messages, and then fill in the missing information that is needed for someone here to possibly help out... Otherwise, they (the people who know stuff here, not me) don't have time to fish for the info.... and you may wonder why you don't get many responses... K
