Good eye. Tom sent us this pic of a really nice stove design he spotted in London recently. We've seen things similar to this, but never one as nicely put together, so that the flat top looks attractive: "I was recently in London where I saw an item that seems like a pretty cool addition to any small kitchen...."
The stove had a glass or pyrex surface--kind of like a cutting board--placed on hinges near the back. When the burners were not being used, the surface could be lowered to add counter space, and could be placed up and out of the way when cooking.
Here are some photos. Maybe you are already super familiar with this, but I hadn't seen it before and thought it might be a useful tip for folks dealing with small spaces.
