Second Floor

With the breakfast nook attached it looks like you have some flexibility in that space. I.e. you could move a table over to the wall for a buffet if you were going to have a big party and needed the space. What are you planning to do in the room? My suggestion.. Go in the garage or outside and mark out 15 x 15 feet so you get a feel for how big it is. Measure your furniture (if you are going to keep it or the size of the new furniture you are going to get. Which wall is the TV going on? What is going to be the layout of the other furniture. Will there be bar stools? Think about the traffic flow in that area. I do not think 15 x 15 is too small (probably would be if it was a walled off room) but that is just my opinion.

A 15x15 living room is pretty small but whether it is too small depends on what you plan to do with it.

You mentioned that you are a family of three (with maybe one more someday) but I see a living room, a family room, and a game room. That's essentially THREE living areas. Plus you have a dedicated office. Then there are FIVE bedrooms.

I won't be like some folks and try to tell you that you don't need all that space - perhaps you have lots of overnight company on a fairly regular basis or expect to have aging parents move in with you fairly soon.

But, with only three people living in the house full time, it does make me wonder how you plan to use the front living room. The family room and game room should provide plenty of space for one or two children to play and the family to gather to watch TV, converse, play games, do chores, etc.

The dedicated office means you shouldn't be needing the the living room as a computer space or home office. So I'm guessing the living room will mostly be a "show piece" that gets little or no use. And in that case, 15 x 15 is plenty big.

What I see missing from the floor plan is any sort of mud-room area. I also don't really like the location of the downstairs powder room and the garage looks too small to park two full-sized vehicles. For comfort, your garage needs to be at least 4 ft longer than your longest automobile and it needs to be wide enough to give you two feet of clearance on the sides and between the two vehicles. Otherwise you're constantly brushing your clothing up against a vehicle when you try to get in/out. And, if there are any steps down into the garage, you need extra space around the steps so that you don't have to park with your bumper over the bottom step.

I also don't like front-facing garages that nose out in front of the house because it tends to make the garage more prominent (noticeable) than the house. Makes it look like you built a garage with an attached house instead of a house with an attached garage. The proverbial GARAGEhouse. If your lot is small and you have no options except a front facing garage, I would at least want the architect to push the garage back so that the house is closer to the front of the lot than the garage.

I'd also rethink having the master bedroom over the garage. Anyone sleeping in the bedroom over the garage is likely to hear the garage door open/close. I'd see if there wasn't some way to move the game room to the spot over the garage and put the master bedroom in a quieter location.

Thank you all for the suggestions. Actually there is a mistake on this floor plan. The living room in the front it is actually a formal dinning area. The space with 15'31/2 x 15'10 it is family room on the back.
@kam76 I am planning to place the TV above the fireplace.
I will place a sofa in the right wall and a loveseat in front of the fireplace. I am also thinking about using two chairs on the left side. I will use two bar stools.
@bevangel I am from Brazil and we receive lots of visits from our family. I will be using one of the bedrooms as a playroom for my son. I also like the garage on the side, but we do not have enough space to do it.
Thanks :)
