Requirements:
-- It must not stink. At all. Ever. The most discerning urban nose must be convinced. (Particularly the female half.)
There are many factors here:
1. Positive air pressure in the "people" part, which keeps all the smells in the "microbe" department.
2. Determining if enough of the "people" are trainable to lower the lid! The seat needs to be flat to the base, and the lid needs to have a sealing surface contacting it.
3. You need easy to use cover material.
4. If I'm assuming correctly, this building will be used for both urine and stool. Keeping those as separate as possible would help considerably.
-- It must be available day and night.
1. The easy solution would be to run power to it. You could likely get away with 12volt DC with the complicated stuff in the house because your 2 uses would be for light and a fan. I have nothing against a small solar panel on the roof, except that during the big dark there's a good chance any batteries would run out if you were really counting on it.
2. There are temporary solutions for bonfire nights, but if this is your back-up for a failing septic tank which I recall from past posts, has frozen on you in the winter, I really do think you need to plan for all weather, all conditions, the worst of the worst.
-- It must not be outrageously cold to use, even in winter.
1. The two things that affect warmth are thermal mass and insulation. Thermal mass is great if your plan is to heat the building year round as efficiently as possible. Thermal mass is a negative for intermittent, short term use. *Lots* of insulation, and that double seal door arrangement Rico suggested, will allow you to heat the space quickly with a relatively small amount of input.
2. Since I'm backing the cold intolerant side of the equation (trust me, I can turn into an icicle faster than anyone I've ever met, and thawing me out requires an external heat source, so I understand this need), and if you follow my advice for getting permanent power out there with a back-up generator, I'd vote for a heated toilet seat. *Nothing* is nastier than having to sit on a frigid seat, and us women have to do it for pee as well.
But there must be a loo in the Taj Mahal somewhere -- maybe one of the outbuildings? Will a few coats of whitewash suffice?
1. Light coloured interior certainly make a place cheerier - no scary dark corners please! However, "pretty" often just takes consideration of the likes/dislikes of your partner, and making the area a) welcoming, b) possibly humorous to make people smile, and c) definitely easy to clean. My one toilet has a glass framed poster opposite it. Not fancy, but better than a blank wall or just the towel rack that's below the poster. My other toilet faces a mirror, which means the picture I hung behind the toilet (planet earth from space taking 40 years ago at least by some astronaut) can be seen in the mirror.
2. Similarly, the outside depends on what appeals to the family. Do you want it to look like a miniature version of a Disney Castle, or are you into rustic wood cabin with a green roof? I would either make a statement, or go for cute but "invisible", myself. Is it a spot you would want it to do double duty, such as garden tools in the entrance?
How would you do it?
I'm still working on it... I absolutely need an outdoor loo, but it will likely be some sort of "bucket system" because it likely will only get rare use unless shit happens (yeah, yeah, couldn't resist). I'm leaning towards small and lightweight so our tractor could actually move it around as needs change, but we don't have your cold weather. I'm also leaning towards more than one because our property is such a weird shape. I'm also in a Municipality which may be "technically" rural, but the bylaws don't reflect that, so having the building do double duty and not "look" like an outhouse has a lot to say for it.
