Unit is comprised of four seperate/independent components (each can be sold separately or they can all be purchased together).
Pictures will be posted when I can. However, the gist is that there are two, main, enclosed shelving units (each, on the exterior, measure roughly 36 1/4" wide by 16" deep by 78" tall). Since they are separate/independent units, they can be positioned side by side or separated (put on different walls or even in different rooms).
Should a giant, wall-sized shelving unit/look be desired, there are two, thinner, standalone semi-enclosed units that can flank (be positioned on the left and right side of the units mentioned above). Each has a straight side and a rounded side. Thus, if positioning all four units side by side, the "left-hand" end unit would have its rounded side facing left and the "right-hand" side of the other end unit would be facing right.
The thinner, end units measure 18 1/4" wide by 16" deep on the non-rounded side (little over 10" on the rounded end), and 78" tall.
The thinner, end units have the same "internal" shelving dimensions/measurements. Each has two enclosed areas with hinged doors (one on the bottom and one on the top) and three non-enclosed shelves sandwiched in between.
From bottom to top, the measurements are: (bottom enclosed area divided into two shelving area (11 7/8" tall and 9 1/2" tall); non-enclosed area having three shelving areas (10 5/8", 11 7/8", and roughly 12"); and top enclosed area (roughly 14.5"))...all by approximately 15 1/8" deep and 17" wide.
Each of these, thinner, end units have a light behind the top, semi-enclosed shelf that will illuminate all three of the semi-enclosed shelving areas.
The two, larger, enclosed units have slightly different shelving measurements/layouts.
Both have top/bottom areas that are identical in measurement/layout (bottom is divided into two shelving areas 12 1/4" and 9 1/4" high (although the top shelf dos have a wooden drop-down piece of wood that lowers the front height of the area, but forward and rearward of the drop-down, one has the indicated 9 1/4" height to use). This area on both units is enclosed by two hinged doors with gold-colored pull hardware. The upper areas measure 14 1/2" high with a similar drop-down piece of wood that lowers the front height of the area, but forward and rearward of the drop-down, one has the indicated 14 1/2" height to use for storage. All of these areas measure 35" wide by 15 1/4" deep. These areas are enclosed by the same type of hinged doors with gold-colored pull hardware as the lower areas were.
Between these upper and lower storage/shelving areas are three additional shelving areas. They, however, are not exactly identical in measurement or design.
The one unit has the lower of the three shelves semi-enclosed (two side walls and back, but no front enclosure) and measures 10 1/2" high. The top two shelves of the three are enclosed behind hinged glass doors. The shelves measure 11 7/8" and 12 3/8" high respectively.
The other unit has three shelving/storage areas, but two of them are semi-enclosed with a pull-down, desk-like door. The lower, semi-enclosed area measures roughly 7 1/4" high. The upper, semi-enclosed area measures 12 1/8" high and the enclosed, middle shelving area with fold-down hinged door measures 15 1/8" high. This area reminds me of where one (if using the unit in the living room or dining room) store some bottles/glasses and use the fold-down door to mix some cocktails on.
If/when I find pictures of the units (prior to the move (uncluttered)), I will post them.
