hi:
I usually hang out in tools, but this is a design issue so..
I need some better (than my own) ideas - the attached photo shows an arch built using 8" x 16" concrete blocks painted yellow. The previous owners of this house put it in when the weight of the fireplace they were building on the main floor above started to collapse the floor. The thing is 62" wide inside the arch, 87" wide inside along the back. The opening is 79" high; inside wall height is 93". The wood attached to the two front facing bits (foreground) appears to be some kind of compressed fiber board attached with concrete nails.
The whole arch forms one wall of a walk in closet I'm building there. The photo was taken from the right hand edge of the door way. The rest of the closet is baltic birch, mahogany trim, stainless steel fixtures (bars for hanging stuff etc), lighting is "daylight" LED.
What should go in the hole created by the arch? ( I have neither enemies nor amontillado )
