We all have to make decisions and accept tradeoffs on our layouts. There never seems to be enough room for everything.
When I first planned my layout nine years ago, I mapped out a nice area for my downtown area (to the right) and open country (to the left).
I mapped out a lot of benchtop space for downtown, because I knew I loved making buildings, etc., (foreground below).
But I left room for open country, too, which I cherish. The plateau top in the photo below is very much like the southern Colorado/northen New Mexico areas where I spent my "formative years."
And I left the entire other end of the layout open country. I was most pleased with my pristine mountain lake: pure water, clean, crisp air, pines, and the Rockies, very much like those beautiful Colorado lakes where I used to go fishing with my Dad and Granddad.
But I never met an O-gauge building I didn't like, and I really wanted lots more 'Streets. After I completed my downtown area, I continued adding more buildings and 'Streets toward the back of the layout. Over the last five years, I squeezed a lot of both into out-of-the-way nooks and crannies like those in the background below.
But those areas filled up, and I find good buildings irresistible. Here is my mountain lake today, with the Creedance Clearwater Brewery (Woodland Scenics Morison's Door factory) and the Burma Shave factory (Menards Feed and Seed). Both are great buildings that I could not resist adding. But I want my lake back. And I also realize there will be other good buildings next year (maybe next week, given how Menards is knocking them out!).
And meanwhile, I have a Woodland Scenics bashed IGA Grocery, a bashed/scratch built TV-Radio repair shop, and Menards Lionel Hobby shop all waiting for someplace to go on the layout . . . with no where to put them. And I know myself, these will not be the last buildings I want to build.
So the empty plateau will go . . . the white area below will become "city" with a new 'Streets loop roughly along the route indicated by the black line.
The Burma Shave factory and brewery will relocate to where the two blue boxes are shown. . .
My auto park, with car dealerships to display a lot of diecast vehicles, at the far end of that plateuu, will have to go . .
As will, my "Ferrari factory" one of my favorite vignette areas.
I'll build more shelves for diecast cars and get these cars and trucks off the layout. The new "city" area will alolow expansion room for another few year's worth of buildings. Not sure what I will go then . . . but for the moment, the "building" can continue.
