Creating a manor/mansion design for survival server. Feedback is welcome.

I was thinking up of a design for a manor/mansion for me and my friends to move in, at our survival server. What do you guys and gals think I should I add to make it look more better? (NOTE: the wood won't be the final material to be used. I only used it here because it was easy to manage. I was thinking of using stone bricks at the bottom half of the manor, then white concrete or quarts blocks at the top half.)
