We purchased two of these kennels and although maybe not as great as "built furniture", these are really nice and are less expensive than the "built furniture" shipping costs, let alone the cost of the kennels plus shipping.  It does take a little time to assemble them but the instructions are pretty decent if you look at the pictures carefully.  Every screw and bolt hole is pre-drilled and every single predrilled hole was perfectly aligned.  The kennels seem very sturdy and durable once assembled.  The engineering and designing appear to be very well done.  So far, we are very pleased with this purchase and would recommend them.
