Construct or destruct to your specific needs. Sometimes it's an unfinished look that you need to finish your vision, and this set will get you there. Two pre-made full loads (they alter the main slab textures) and an elevator shaft prop means you can get rendering is as few as two clicks.
Additional column props with column caps means you can do the work yourself or kit bash the set. Two slab props come in handy for extending scenes, or you could use them as bases for a glamor shot.
