Had my guy fit them, he was impressed with the way the units were put together  attached to the wall.  This unit has solid side panels but other items like the corner unit  shelving have the little holes for the shelf on both sides of the panel so don’t look quite as nice when not attached to another unit.  Another issue which isn’t shown very well in the photos in the website  is the hanging rail is right at the front so your clothes stick out when in the rail.  My guy drilled holes so the hanging rail was more in the center so only a small part of the hanger now sticks out which looks better
