I'd argue to make various sets of timber frame blocks, so the blocks can be combined in a single building. With this I mean a limited amount of timber frame colour, while most of the variation is in the infill. We already have a fairly large "oak" set, with white daub, brown daub, brick, Reach stone and Oldtown stone.
My suggestion for another set would be black wood, with white daub, yellow daub and brick.
In addition we could think about combinations for specific regions, like we did with the Reach and Oldtown timber frame. The Westerlands for example could benefit from oak combinations with Lannisport stone, orange daub and yellow daub, while the Vale might benefit more from black wood combinations with light grey stone, light blue daub, red daub and orange daub. Kingslanding might have some houses still painted in the old colours of house Targaryen; black timber with a faded red plaster, colours which would also combine well with the darker palette of the Stormlands.
That sounds good - I like the idea of regional variants. I think a breakdown of proposed new sets/colors would be most useful at this point, since I'd like to quantify the number of new things to be added and organize them before I begin any work on it.
I'd like to make a case of introducing more timber frame variants. I don't think introducing new variants of timber frame would outdate existing builds. The projects you mentioned did a great job with timber frame patterns, which will not become any less good if different shapes are introduced. Projects are much more prone to be outdated (and are much harder to update if needed) with the introduction of a whole new range of nature blocks, updates to flower blocks or the introduction of river pebble.
I appreciate the follow-up, though I'm not really convinced. The way I think about adding more timber frame variants is that it increases the "resolution" of the patterns that we're able to create, when viewed as a capture of IRL examples (an analogy that I've used in the past). When looking at the regional variants like proposed above, it's sort of like looking at two different photos with the same resolution, but different color choices. It's not immediately clear which photo is better in this case; it just depends on what the photographer is trying to capture. By contrast, when looking at adding more timber variants, it's like looking at two different photos with the same colors/etc., but with one having a higher resolution than the other. In this case, people would generally think that the higher resolution picture is strictly better, even if the original photo was decently high quality.
It's not a huge deal if I just add the close studding variant (as Dutch said, it's more "all or nothing" anyways, so can be sort of a regional variant itself), but I think if all the timber shapes are added, any builds since will be higher resolution approximations of the IRL houses, such as the ones in the inspiration album you linked. Which has the benefit of letting us make more realistic things in itself (i.e. more artistic freedom), but I'm worried about the cost of making areas like Duskendale seem like the "lower resolution photo" in the example above in comparison. To me, that seems like a pretty big cost when looking at the amount of d&w builds on the server that would get suddenly deprecated based on that alone.
You're right that the nature blocks have done that to some extent, but my motives for shifting focus to nature updates a few years back was (in addition to our nature standards lagging way behind our building standards at the time) that the completion rate for nature/terraforming was far below the completion rate for settlements. The latter is around 60-65% last time I checked. I'm not sure what the completion rate for nature/terraforming is, but I'm going to guess it's far less than that, considering that the majority of the map is still default WorldPainter terrain and that people are only heavily focusing on the terraforming aspects of projects within the last few years (partially as a result of the nature revamps that happened). I think that terraforming, as well as smaller immersion projects in empty areas, will become relatively more important as our project gets closer to completion, which is why I've been a bit warmer to adding new nature blocks in general.
