Think of it: a wall oven with a side opening door rather than an awkward pull-down door. Top-of-the-line Gaggenau offers this great feature on their EB 200 series of built-in wall ovens, which can also be installed under the counter. The oven doors open to a full 180 degrees (like a microwave), making it vastly easier to access the interior. The door handle is set far enough to the edge that it never becomes hot. Gaggenau ovens are known for their amazing temperature control and for other advanced features such as child safety locks. More information at gaggenau.com.
