I have a large townhome style duplex where the lot size and zoning support additional units. I'm doing a set of new construction townhomes on either side of the existing structure. 

Any tips for color coordinating the new construction to gell with the old?

I was thinking about painting existing brick white then painting trim black. The existing brick color is meh.  But not a smart maintenance move to paint brick. Side note trying to avoid brick for new construction due to size constraints. Also side note the entrance to townhome on the left is on the side, that entrance will be moved to the front.
