Jenna 1, Palimpsest, and others, I find myself wondering how much the original feel was changed in the renovation. For instance, I think the ceilings would have been a warm wood and the floors carpeted. Also the wall colors would likely have been warmer colors - off whites perhaps. The colors of the nursery walls seem most in keeping with the colors I recall from that era, but the greys of most of the other walls seem cooler or, perhaps, more subdued. I find it interesting that the renovation may have kept the original sense of openness and light but may have given the house a cooler feel. I am not sure that is an accurate perception.

Pipdog - Sorry, I missed your earlier post. That house was the inspiration for one of my neighbor's remodels! Interestingly, they painted everything white BUT the fireplace and put in similar light wood flooring. Their fireplace is on an outer wall, not in the center, so it doesn't really stick out. Palimpsest - LOL on the mullet. I admit, I did have a mullet haircut 5(?) years ago when they were back in style, and DH had the faux-hawk. But hair is temporary by its nature, and I like looking silly. :) I didn't mean to be dismissive of "whatever this is" but I honestly don't know what to call it. I'm a big fan of modernism, and I'm clueless when it comes to transitional decor. I understand modern design principles, but ask me which chair goes with which table in a transitional home and I'm at a loss. And I'm really not a preservationist. We are making significant changes. The siding is definitely not original (I'd argue better than the stucco). We're updating the kitchen and baths, removing walls, etc. And our furniture is definitely not period correct. The house I posted above with the metal sheets is from a Dwell home tour and dubbed the "Hyper Eichler" by the architect. He approached the update by considering what the architects / builder might have done if the materials and building technology of today was available back then. I think it stays true even with the numerous changes from the original finishes, and I try to keep this approach in mind. Marcolo - I don't know that wanting to paint a fireplace or making any non-standard MCM chalterations is necessarily due to a lack of appreciation or trend following. Most of my neighbors truly believe they appreciate the MCM nature of their homes and probably wouldn't know a current trend if it hit them in the face, but they make all kinds of changes that purists would cringe at: granite counters, shaker cabinets, atrium conversion, fireplace removal, wood flooring, etc etc etc. A lot of it is due to tweaking their homes for their lifestyle (fireplace in the way, needed sq footage from atrium), or something I often hear is the emphasis on natural materials (granite counters, wood floors) despite the fact they're replacing formica and VCT.

There is also a ReStore on 242 E of 45 outside The Woodlands and another in Conroe. There may be more. Sounds like you are on the SW side -- maybe near the Meyerland area? I grew up not far from there. Look for the size and finish fan you need, then buy LED bulbs and dimmers for them. When Harvey hit, I was helping my sister ready her former home for a post-divorce sale. We installed 8 fans and 5 of them were Hunter nickel or stainless finish with with wood blades (I think the blades were reversible with a midtone and a dark wood finish) bought at Lowe's. Hers were something like this https://www.lowes.com/pd/Hunter-Waldon-5-Minute-Fan-52-in-Brushed-Nickel-Indoor-Downrod-Or-Close-Mount-Ceiling-Fan-with-Light-Kit/4332172 but this one might be more in keeping with your MCM and it comes with a remote. https://www.lowes.com/pd/Kichler-52-in-Nickel-Indoor-Downrod-Mount-Ceiling-Fan-with-Light-Kit-and-Remote/999919012.  Sorry I couldn't get the links to work, but hope that helps. I think medium to dark wood tones would look good with a grey floor and walls. I would avoid going too light and you can certainly mix wood tones, though most pIeople go within a light to medium range or medium to dark range or use different tones in different rooms. Formica or IKEA butcher block sound like a great way to get the most bang for your buck, though I will mention that we did the kids' bathrooms with prefab granite and 8-10 foot lengths started around $150-200. If you just have straight runs and are happy with a rolled edge, that can work.

Doug fir t&g would be very period correct, especially in a square channel groove vs v-groove pattern, but either will work. Redwood was also used extensively in the '50s, but finding clear heart without white sapwood is going to be difficult and very expensive.
