Does anyone have any input on shelf layout height? I am finishing a space in my attic for my layout. I am limited as far as height for my layout due to the roofline. I was thinking around 36" since I could roll around in an office chair. I am designing an around the wall shelf plan with a peninsula in HO scale. With a 36" layout height and 12" backdrop height would result in a 12' wide by 16' long total space. Acces is via pull down stairs surrounded by 4' half wall and Dutch door so nobody falls down stairs. Any suggestions would be greatly appreciated. God bless and happy modeling!
