I would get all new windows with no grids and choose a color from the stone for the garage doors It owuld be helpful to see where you are planning the garage and some major landscaping is in order. No idea about the pics you posted none of those are even close to your house .

There’s nothing wrong with a garage addition looking like a garage addition. You tie it together with color, roofing, and the same windows.

Patricia Colwell Consulting The windows are as important to the style of the home as the stonework. Perhaps you have it confused with a more modern home. We are in the process of installing exterior French drains around the homes perimeter which necessitated the removal of the existing bushes. The top picture is a true representation of the stone on the house.

judfor1, you own an absolutely an adorable house…what if the garage siding were applied vertically and you let it weather out? Love this photo for inspiration. The only change I would make is to paint the window trim the same as the house trim.

New storm doors?

JudyG Designs Our list is long, and new doors, and painting the trim, and … are on the list. Yes, I have been thinking hard about the window colors, but the garage really manages to occupy my mind a lot.

I do nort see anything particular that requires those windows that BTW look like they all need replacing adn indeed all the stone work on the entry

What a great house! Beautiful stone! I think my cousin has something similar - she's in PA - beautiful metalic like flecks in it...

My thought is don't try to match any stonework - it won't match and will stand out like a sore thumb - like mixing new brick with old brick. Looks like on the side you have a bit of cedar shake siding. I think that would look great on a garage! It weathers great with no upkeep, and over time will look that much more like it's been in place a very long time.

Are you going to keep the garage separate from the house? I think that would look better. Or connect it with a breezeway,,,,

I think I've just discovered a so-called PRO that I'd be sure to never consult with!!

While I am not a professional and I know this is not the usual, but I would pick out a dark grown tone from the stone and use it as a trim color, instead of gray. There are so many grays all ready. Love your home!

Anna (6B/7A in MD) I live in Baltimore County just 5 miles this side of Harford County. The photo makes it look odd. That section of the house is the original garage. Not sure how they managed to get a car into it. We plan to make the window into french doors, and block the door just to the side with the exception of a small decorative window.

Nancy Fisher I am not a friend of the "trendy" gray that seems to be everywhere either. My goal is to have a weathered look.
