Wow! Love seeing more replies - even with pictures!!
@NRALIFR - Thanks for the link to your thread, I'm now subscribed! I was trying to search the forum for posts about RV Garages, but those words pulled up so many hits that I couldn't find relevant ones.
@SolidAxleDurango - We also plan to have a drive-thru garage, with doors on front and back, as this building will straddle a crushed asphalt driveway that goes from the front to the back of our house. Ours will be much narrower than yours, however...
Currently leaning toward 12x14' insulated doors with 16' interior height. Still contemplating the length and width. Some of that decision may be based on site considerations: setbacks, a ditch easement we need to work around, etc.
Anyone have any pricing thoughts? Cost/sq. ft. ranges? Right now I'm mentally in the 20x40' ballpark, but need to draw it up and use a tape outside to see how it fits my vision. An added cost is that we'd prefer to match the exterior of the house, so we'd probably do stucco/stone instead of a steel building. I'm afraid to find out how much that will add...
I'd like to save costs where possible, without kicking myself in the future (if possible). To that extent, here's my thought on some of the suggestions that have been mentioned that I'm currently NOT planning to include:
-Floor Drain/Water: Our layout is actually really similar to
NRALIFR's. If you look at his "Existing South Elevation", it looks a lot like the front elevation of our house. We have an oversized three bay garage (1500 sq ft - fits four+ cars - our RV would fit if we had a taller door...but the house was built before the RV was in the picture and I'm not interested in the remodel route) where his two car garage is/was. Then it slopes over to a secondary driveway going around the right side of the house. We'd put a narrow RV garage there, just like his drawing (thanks NRALIFR for the visual aid!). We have a large driveway in front of the existing garage which has hot/cold taps, a work sink, etc. Washing the RV there isn't a problem, so I don't see the need to include water/drains at the new structure. And, if in future someone had a bigger RV that couldn't maneuver in and out of our main driveway (it does have a hammerhead per county requirements for firetrucks to turn around), a hose would reach down to the other garage and our dry Colorado ground would love the moisture (assuming no harsh chemicals are used).
-Dump Station: We already have access to one off our existing driveway. Again, a giant RV or long 5'er may not be able to make use of it as well (works best with waste valves near back of RV), but we don't really want to go giant and knowing where the sewer line is, adding a dump station at the garage would not be a simple (or cheap) undertaking.
Anyone see a flaw in my logic on those couple items?
