Yeah that works, looks ok as well. When upgrade to the tile based roof it will look better.

If you look at an actual longhouse you will see that so much of it, is just roof. But I would like to see a whole bunch more roofing options so that a curved ridge roof is possible. Even a stepped ridge roof is tricky and time consuming given standard building block is 1m, a 0.5m piece would be useful in roofing.
