I was thinking that because the Trubridge lights are so beautiful, a simple LED pendant light would be best as they do the job without taking away from the beautiful light!

I really don't see an issue with the rooflines. Looks like the angles are fairly similar and the clean lines of both structures should be easy to coordinate, especially in your open, rural setting. Since you've found a stunning deal, I would say, go for it! I definitely would want to find an architect ASAP and by all means, before you pour the slab, make sure you have a plan to coordinate.

Nobody's asking, but I wonder what a wood garage door would look like, something to bring out the bit of brick at bottom....I liked our split level.

Oh wow, it looks fantastic! The black looks so striking against the white, not too sharp at all. Congratulations on the house, you must be very excited to move in. :)
