I've been using a term lately that I picked up on one or more of the fora I frequent but I thought I would talk about it a bit - restovation. It's being used as a catch-all when a homeowner is doing some remodeling and he wants to be sensitive to the original architecture - a composit of Restoration and Renovation. Sort of the opposite of a remuddle (another meme indicating that a remodel done poorly, especially one that isn't sensitive to the building's intent or architecture) - I'll discuss both in regards to mid-century modern homes:
RestovationMy take on a restovation is to make architectural changes that are close to the same or at least sensitive to the original builder's intent - basically to make alterations that either can't be detected, or to remove a poorly applied remodel by replacing or "fixing" with something that could have been part of the original builder's construction. When at all possible I try to keep original features and refurbish when necessary (at minimum a good cleaning does wonders - sometimes I'll try to fix fixtures and such or replace with something that's close). Of course there's varying degrees of restovation - some things that are missing simply can't be replaced and compromises have to be made, especially when fixing a bad remuddle. The trick here is to find replacements that aren't complicated - usually the simpler the better. The other trick to being successful is to use patience - that missing something or other could be waiting on the curb in your neighbor's trash a year from now.
RemuddleIn general a remuddle is any remodel that isn't sensitive to the architecture - like replacing the front door with some obnoxious Home Depot purchased beveled glass monstrosity or putting a bay window on the front of a modern house. Neither of these would have been part of the original mid-century modern design and only "muddles" the clean lines or hides that the house is modern. You'll see variations of this - the addition of shutters, ornate exterior sconce lighting, an added Bay window, the list goes on.
A good restovation would incorporate good, clean design changes, keeping elements that are both appropriate and still useful for the time we currently live in. I'm not at all opposed to updates, especially to the kitchens and bathrooms of mid-century modern homes - often the tile is cracked or otherwise rundown and defective, or the original cabinetry is failing and it's simpler to replace rather than repair - plus you can't beat the new cabinet hardware and storage doo-dads that are available now. The trick is to remain sensitive to the original house design and intent (French Provincial cabinets simply look ridiculous in these houses). When possible I like to keep the original kitchen provided it's in good shape and restorable - I'll discuss this more in future posts by showing effective methods of doing so.
A bad remuddle would have one or more of the following :(I lifted this from the Lotta Living forum post "100 Ways to Screw Up Your Mid-Century Modern Home" with a couple of edits)

Here's a good article about 4 renovation trends that
should go away.-- John
Note the intentional resemblance in the floor-plan to the well-documented Hanna House in Palo Alto, done by the master himself. When we first pulled up to the drive I knew we were in for a treat - the roofline from the road, the natural stone, and great fireplace all provided hints of a wonderful structure. I took a few moments looking around the empty house before entering, as evidenced by the photographs in my flickr gallery. 
The bedrooms and bathrooms, with the exception of the master, are small, featuring built-in dressers (the drawers are often built as parallelograms to match the angles of the walls. The beds and nightstands for the most part are also built-in. The spaces all take as much advantage of the view as possible by providing floor-to-ceiling windows and utilizing the remaining space as efficiently as possible. The master has an additional private room with balcony which is overlooked by the bed, which is surrounded by built-in shelves. There are many areas providing natural light both in the walls and ceiling via skylights.
