That sounds like a Tulikivi from Finland ?
That was what I had my eye on initially. They are beautiful, but even more expensive than a built-on-site heater (since everything has to be shipped from Scandinavia) and I have to admit that soapstone wouldn't have fit the style of the house as well as a big stone-covered monolith.
My original sketches for the house had a straight-walled two-story great room with flaming torches around the periphery, a walk-in fireplace and a chandelier about the size of a mid-sized car. It was immediately vetoed by the real-estate agent
