Very cute house. I personally like as is so if it needs to be redone I’d stick with a light color. I think dark charcoal will close the house up too much. I love how airy and inviting it looks right now.

I do not thinks grids are the answer for the windows but I do agree to leave the brick as is and think about a much darker color for windows and trim I would also lose that bay window and get a black front door .The front porch can be quite attractive once you can see it after the hedge comes out . IMO landscaping will do more for the house than messing with the brick.

The other thing you may consider to change up your exterior is to change out the posts and railings. The posts could be beefed up and a new classic, yet modern touch for the railings. Possibly even consider cedar posts instead of painted ones.

I think I need to understand what the reason was for the blue. I can barely see the house in the pics so hard to really understand the color choice . I would rarely use a dark blue with black windows . I agree the glaring white huge garage door needs replacing and for thta I would choose a door with some glass in it and then I like the idea of the wood . Gutters are IMO not decor elements so either match the roof or the fascia .which is white now and honestly maybe black for both the gutters and fascia to tie in the black windows .I am not sure about the soffits.
