Ops ahaha.. Actually i had never ask what type of woods will be used. Cant even tell which is what. hee..
Actually, i had no intention of installing any glass panel, wanna keep it as a open concept.
The outer layer of the book shelf was suppose to be for novels and comics, whereas the inner layer are meant for reference books and magazine. I want the book shelf partition layers to be adjustable, as and well its require. So i had actually suggested to use "railway track" for each individual layers of shelving, but the contactor had rejected the idea. As he felt that it might be too weak to support the weight of the books. From what i understand each individual column will be ard 33inches in lenght. I had been to those comic shops and book store for on sight review, somehow they all seem fine. So i am hoping for someone here who might had faced the same situation to share with me your experience or even advise.
