I like the idea of a 'brand' or 'mark'. It does not need to have anything with a roof. Could you work more with the S and the H? Maybe even extending the top and bottom of the S to the left and to the right? I do like the circle, too. Thanks!
This is definitely the direction we were trying to head with this. If you could do some different variations to see if we could make this work and I will get you more feedback. Thanks!
