Yes, it will be too narrow.

So here's the rest of my opinion:

-The most prominent feature of a house should never be the garage doors.

-The front entry should be clear, welcoming and should guide the visitor with visual cues.

-A front door that's hidden in a dark tunnel is awful.

-A home needs a "front side" - that's not always the side facing the street (yours isn't). Building the garage in front of your existing would completely block the "front" of your house.

Here's an idea: Put the new garage behind the existing and have the garage door on the side of the house instead of the front. Rework the drive a bit --to the right of where the car is parked --with pavers so that it's a "drop off area" that helps to emphasize the "front" of the house.

You have a nice house. Don't mess it up with a remuddle job that gives you more sq feet but ruins the house in the process.

Hi Jake thanks for the advice! One problem, we have an addition on the back of my house so I can build a garage behind the garage. Also I guess I should explain further. Our house is 2286 sqft, which is not small, but we want a den. I don't have a basement and my addition is 544 sqft which includes a sunroom, bathroom, and second primary room. Any suggestions of creating more space without doing a second story addition?

Can you explain what a "den" is to you, functionally and space-wise? Living room, Family room, Office, "Den"? A garage is somewhere around 20x22 usually with tight access through the Laundry or Kitchen, how does that conversion play in your wants? How much room to the left of the garage before the property setback?

Because of your roofline, it would be easiest to put it on one of the ends. If you don't have the space for that, I would do a detached garage a little further to the left if possible.

Not only will you visually lose your front entrance, the garage will be the entire focal point of your home.

If you have room to the left for a garage (single or double depending on lot size), den would have a breezeway effect.

Thanks everyone! So right now my my kiddos have a playroom/sunroom (which is in the addition). The addition is 544sqft and we want to take a portion of that and turn it into a master en-suite. The sunroom is now 240 sqft and we will be making it 150 sqft. So we wanted to replace this large space with a “den” like area which would be the old garage. I hope that makes sense.

I also agree that the space would be too narrow between the garage and front of the house if I bring it up,but the current garage has the most space to use at 700sqft

I think that you have a challenge to do what you want and make it look good.

Given the challenges, I'd enlist the services of an architect, not a builder, to give you options.

As an option if you can fit another 10'-12' on the left you can do a partial cover of a garage, leaving room for a window. Time to get a local architect's input.

Is that huge back addition built on an existing deck above grade (trellis crawlspace cover)?

Yes it’s above grade
