casa principal reno desde un rancho simple de los 70 hasta una casa de río moderna en la montaña

This project involves a major renovation of a single story, 2-bedroom ranch built in 1978 and turning it into a 2-story, "mountain modern" home here in eastern Idaho. I live on the Snake River (facing east) on a ~1acre lot and the views are beautiful so I would like the eastern side of the house to take full advantage of the water view. There are mountain ranges to the east and the west, so I would like to see those views as well. I anticipate using the existing foundation and expanding the footprint, and adding one floor. The house has a finished basement with a small bathroom and I won't be renovating that space (with the exception of possibly moving the stairwell) as it was recently remodeled. To keep costs down, I don't want to expand the basement so I will be using a slab foundation with footings for any expansion of the footprint. The existing house is in fair shape, but I envision a substantial remodel, moving most of the interior walls of the existing structure and expanding the outer walls on to the new footprint, so the new structure will not look anything like the existing structure. I don't know what the resulting size of the house will be after the addition. It may be over 2,400sq ft. I would like to keep the budget at ~$250,000USD but can go as high as $300,000 if I absolutely need to.

- using corrugated steel or metal cladding, wood, concrete, glass (mixed textures and building materials)
- simple, timeless, and rustic "mountain modern" design with a focus on ease of assembly/building (efficient/minimalist)
- design to reduce cost wherever possible (labor is big part of cost hence designing for assembly/building)
- garage expanded to accommodate 4 cars + space for workbench, most likely extending footprint east toward the river
- contemporary garage doors on both east and west side (frosted glass on west side facing the street, clear glass on east side so
I can see the river views)
- outdoor shower with some privacy
- 2nd floor balcony, perhaps going across entire rear (east side) of house (facing the river)
- extend current height of fireplace to be 2 stories, with river rock replacing existing lava stone (at least on interior the house)
- loft on 2nd floor with cozy reading area open to living area ("great room") and fireplace below
- kitchen on first floor facing east, with windows across the entire east facing part of the house if possible
- modern, clean, simple, elegant kitchen. Not fancy.
- perhaps extend southeast side of house, opposite garage, to include a covered, open-air outdoor sitting/eating area, making footprint U-shaped. Perhaps the 2nd floor can be extended to cover the 1st floor open eating area.
- deck on east side of house, between garage and covered, open-air eating/sitting area (w/sunk-in hot tub)
-height of first floor increased to at least 9 feet, with at least 9-foot height on 2nd floor. This will make great room with fireplace
approximately 18 feet in height from floor to ceiling for great room. 20 feet would be better, if it's not too expensive.
- industrial interior look with exposed HVAC, etc., open web trusses. etc. (industrial but still warm)
- see-thru interior stairs (tread but no visible risers) going to 2nd floor
- maximized view of river and 2nd floor view of mountains on east and west side of house.
- 2 or 3 bedrooms on 2nd floor, small laundry room, loft area, lots of light
- master bedroom on 2nd floor with bath and hopefully balcony
- at least one other bedroom facing east with bath
- existing bathroom (and laundry) on 1st floor reduced to 3/4 bath to make more space for great room and foyer
- breezeway on 2nd floor, connecting loft area to one or more of the bedrooms
- staircase going to 2nd floor directly over staircase going down to basement (saving space?)

Affordability is particularly important given the extensive renovation and my budget. I like elegant design but not fancy. I love rustic but modern, and I love materials and textures. Generally speaking, I don't like drywall, but it has its place in residential construction, so I'd like to minimize its use if possible. I love bold colors. I'm not scared by anything (with the exception of huge price tags). I like the contrast of different materials and things like old beams with new materials, or re-purposing old things. I do live in a cold climate, so this house will have to be well insulated, but there are a lot of great views so it will be a balance with all the windows. Be bold - I love love love bold designs. I also have a nautical theme going on right now, so try to work that in if at all possible. Most of all, have fun with this!!
