That's way cool being incorporated into your deck. However, I'm doubting that I can pass local building codes with that. As it is, I'm required to build it 6' away from the house or attached deck.
Having rethought the walk across the yard pain, I'm pretty certain I'm going to end up with option #1 in my pic. It's down the deck steps from my kitchen, but I've also recently finished my basement and have a kitchenette that works great for prepping.
