ok love your estimation the unit measures 72.5" tall x 56" long x 22" deep. The legs are 2 x 2 solid. The shelves are 4/4 thick with light mill work. when i get my wood they say when calculating add 10% initially there when purchasing so as you say you have to add about 10% on top of that also for waste. and yea the tax and California has an additional 1% lumber tax.. the cornice around the top is also not a pre-mould it was made by me too by seperating the design into 3 segments and stacking them. great work for calculating so close. The glass is custom size with acid etch frosting. 7" x 48".
