Wazzzza: I've been following your thread for a while now and amazed how calm you seem when you have some pretty interesting challenges or changes that were not planned. good for you and it looks like it is coming along nicely.
originally i saw the title which interests me because i'm 100% Norwegian and living in Seattle, Wa (USA). then i saw your view and want to visit Norway even more now because I've never had the privilege yet. I was a Realtor for 30 years (sold new and used homes) and you've got what we used to call location, location, location which is a good thing.
here's a couple things i can share with you that might help. since you have such a nice view are you sure you want to stick with that smallish window on the view side of the garage or was it designed that way because of potential heat loss? might be easier to put in a big window now, but that can be done later so you can remain on schedule. Maybe just rough in the framing for the bigger window while you have the wall open then if you ever want to put one in later all you have to do is cut out the siding to the rough framing.
also did you have the trusses changed from the ones that were originally delivered because you have storage up in that area? is it possible because we all can use more storage and a pull down ladder or even a hole that you can put a ladder up to that space might work. or if you need the insulation to keep the garage from getting too cold then that is understandable.
are you planning on bringing the grade of the gravel up to the garage floor or pouring a cement pad? since you did such a nice job on the garage's floor if you still have a budget you'll like the cement much better especially when you have nice weather and just want to work on your vehicles outside. or do the cement in the future if gravel and time are all that are in the cards for this season. i poured 6 inch sidewalks with rebar and other steel in them so it wouldn't crack when most contractors pour 3 or 4 inches, but your climate is a bit colder so not sure how thick you should pour yours.
if you want to make curves in the edging of your cement i used a recycled product called Trex that comes in 16 foot lengths and it's an inch thick. it bends fairly easily, but when you get close to 90 degrees you need to take your time and do that in stages. I was able to put cement stakes in at the bends to hold the curves and it worked out great.
Feel free to ask me anything if you have any questions or if you want to see a before and after of a front yard summer project i did building a Cedar Pergola with the sidewalks i mentioned.
keep up the great work and looks like you'll have it buttoned up before the weather turns which is awesome considering you are not able to do it full time.
