The stone and brik isn't the real problem - you are focused on it because there is no "design" to your yard right now. Take off the shutters, update your railings, and then focus on landscaping.

Well, I agree about the shutters and landscaping, but really the stone and brick are not great together. I'd be tempted to stain it all a deeper gray and then use a bright color on the door. Here are renderings in three stages...

Hope this helps!

Definitely remove the shutters. The roof color is off with the stone.

The stone and brick combo was done with some frequency mid-century where I live. Maybe that's why I'm used to it and it doesn't bother me. I do hate when people paint brick and stone, so I would leave it alone. I agree with the previous commenters that the problem is actually the roof color, shutters and lack of landscaping. Obviously you're not going to replace the roof until it comes to the end of its life, so ride that out, work on the landscaping and be grateful you have a no maintenance exterior. If you paint the brick and/or stone you will no longer have a no maintenance exterior. I can't tell what color your front door is. It's possible just changing that would be an improvement. Show us a closer up picture of the front.

There are probably a lot of things you want to do to the interior, so spend your money there and see if the exterior grows on you.

The front door is a dark walnut stain.

I must agree with removing all the shutters.

I would paint the Brick a tone to match/compliment the stone, a light gray/beige.Taupe

It will make the house look larger and fresh in the nice green setting.

some nice mature trees for a backdrop. Keep it simple.

I would remove the shutters; keep the stone and paint the brick.

B.M. Thunder for the brick.

B.M. Vintage Charm for the front door.

Paint trim, gutters the white of the windows.

Yes to removing the shutters. They were never original. Nor was the door. The house has great modern lines. I agree to leave the stone and brick alone. And then….get a new door, new modern railing (if one is needed), new house numbers. And LANDSCAPE. Stripping back the faux traditional additions will return your home to its modern style.

PS: AND,if possible, remove the interior grids from your windows.
