If you are looking for one to use outside, check the operating limits for the batteries. I had one years ago, but the sensors never lasted long because the batteries didn't like temperatures much below zero. The technology may have changed, but it is something to be aware of.

You don't think 18x20' is big enough for family room? We like to gather in the family room and that's where we spend most of our time together as a family. Are there any wasted space that you see? Yes lots of wasted space and the room sizes are not what they seem. Here in the first plan, I drew in red the walkways to get to other rooms or to get to a door to get outside, or to a closet. These need to be a minimum of 3' and 42" is better. 3' is tight feeling. Notice how much of the house is taken up with walkways? So for example. The living room which says it's 16' x 22' really isn't. The 22' is really only 15'-16' deep because of pathways. However the width is even worse. First you have the fireplace wall which takes up 1'6" right there. Ideally behind a seating area at a counter you need 5' of walking space between the counter and for example your sofa. So now the 16' width has been reduced to 9'6". (16' - 5' - 1'6" = 9'6") Even if you skimp and make the area behind the island 4', that still only leaves you with a living room width to put furniture of 10'6". Considering a sofa or large chair is 3' deep, that now leaves you with a space that is only 6'6" from the fireplace or again if skimping on the space between island and sofa 7'6". Similarly, the nook which says it's 10' x 8' isn't. You'll lose 3' because of the door to the porch so the 8' is now only 5'. However the loss because of the pathway to the game room is even worse. It's not a loss of 3' like someone above suggested. It's almost double because those are double doors. Assuming those double doors are 5' wide, then the space for the nook is only 5' x 5'. A very small table is 3' x 3' so where is the seating room? The second layout is a bit better, but still nothing wonderful. The living room will not be 20' wide but will be 17' wide. Still not shabby though. However the 18' width again you need 5' between seating and island countertops so now your width is down to 13' wide. Plus you will have the problem of how to lay out furniture with a corner fireplace. Corner fireplaces are a bear to lay out furniture in. And again with the nook. the nook will not be 10' but 7' wide and the length will not be 12' but 9' wide. 7' x 9' is doable for a small table and chairs. Also as others have said, even if the houses are oriented north/south, they will still be dark on the interiors. Light can only penetrate so far. One thing you haven't told us is how big is your property. These two plans are meant for suburban lots and not if you have acreage. If you're building on acreage, look for plans that are long and lean. Or, I, T, or H shaped Add to that a U or L shaped plan too.

Echoing what the others have said, that glass shows all the splatters, is a PITA to keep looking clean. Also, as M said, mesh filters, which that glass one has, are a worse choice than baffle filters. I cannot tell what kind of filters the all-metal one has that you show. You want to find a hood with baffle filters. Mesh filters become quickly clogged with grease which blocks the exhaust power, unless you are cleaning the filters constantly. Baffle filters will also need to be cleaned, but not as frequently, and if you do not clean them, it won't block the exhaust. Check out Costco for occasional deals on hoods.

Indoor or container plants are generally not mulched. Ever. Even those that grew outside but are being overwintered due to hardiness issues. There is really no need and mulching can impede water percolation and drainage. Unless inside the house under very dry, low humidity conditions, the container is unlikely to dry sufficiently to require more than just the very occasional watering.
