Mid Century Modern is an aesthetic, a style. Just because something was produced post-WWII through 1970's doesn't automatically classify the item as MCM. This video explains the style better than I could here with my limited typing and grammar skills. https://www.youtube.com/watch?v=-DsIkNuqj-U&ab_channel=JoanaAlmeida More on reddit.com

Do you think flat roofs and window walls have fallen out of style? Modern houses contain many of the features that were made popular in the 1950s. Now they paint them all black and grey and add a rooftop patio and a bigger garage More on reddit.com

Insulation may be in your future. There are many ways to go about it. Have in reserve 50,000 dollars or more, for changes you may desire over the coming five years. Simply having, or planning for an electric vehicle is reason to upgrade to 200 amp service. Each house is different, with its own problems. More on reddit.com

1963 house, one of three in my neighborhood in this style. Love: It is unique (except for being one of three) It is very open, the living room is huge, well suited to parties Daylight basement (finished in wood paneling) is like a party grotto, funky and inviting with access to back yard in good weather It stands out more with every year as the outer suburbs are overrun by faux Craftsman Mini-McMansions Ready availability of used and new-reproduction mid-century furniture, furnishings, and lighting means it isn't too difficult to furnish the house in correct period stuff (although geez, it's expensive!) Hate: Old infrastructure - wiring, plumbing, ductwork. It's all slowly wearing out and is a giant pain to work on. As someone else said, no walls are true or plumb. And many previous-owner work has had to be fixed or ripped out because it wasn't period-correct Flat roof with skylights is an absolute nightmare in Seattle's climate. There's been a new leak every other year since I moved in. some old and energy-inefficient windows can not be upgraded without seriously compromising the look Lack of storage - closets are small, and few. One whole bedroom is used for storage for our outdoor equipment Known tested asbestos popcorn ceiling in the basement. I plan on removing it soon, when I can devote the necessary time to do it (I'm figuring a week). In general, a couple of the really obvious mid-century design elements also contribute to making it hard to own and maintain a mid-century home. The classic floor-to-ceiling single-pane windows are often the most noticeable and obvious style element after the roofline. Keeping them original for the looks will cost you in cold climates. Replacing them with modern efficient windows that look close to original will cost you as well. Roof maintenance is probably next: Live under trees that drop leaves/needles, and/or a rainy climate and expect to go up there to clean the roof and gutters often. A lot of mid-century houses used hidden gutters instead of a tacked-on metal external gutter. The fascia board was tall, above the edge of the roof, and the downspouts penetrated the eave. These are weak points, prone to leaking and clogging. The electrical code was also far different back then, and common wiring practices then may make it difficult to upgrade or add modern electronics/automation. My house, for example, has something wonky where too many neutrals are tied together (I think), and in some locations GFCI outlets just will not frikken' work. And the panel is a mess, I think mostly the fault of some previous owner that wanted to create space for several added circuits beyond what it originally had. More on reddit.com
