This is the stairwell that links the existing ranch home to the new two story addition. The skylight at the top of the stairwell combined with the series of 8x8 glass blocks provides natural daylighting throughout. The material that the stairwell is made of is a ground face concrete block. The curved pipe railings are stainless steel. http://www.kipnisarch.com Photo Credit: Cable Photo/Wayne Cable/ http://selfmadephoto.com
