Upgrading to concrete? Begin with the floor

[Tevirik]

After long hours of harvesting the resources, I was ready to upgrade my little stone house. So I happily upgraded the 4 walls, then the 4 roofs and... everything collapsed on me! Nooooo. Concrete is so expensive and I just lost 4 walls and 4 roofs.
If you upgrade, begin with floors. Yeah, of course, it makes sense. <So annoyed with myself>.

I have a house with a wooden floor and stone & glass walls. I found everything collapsed as well, until i had stone pillars between each wall. I"m wondering if, in your case you just needed concrete pillars next to each wall? I might have to test it and see.

More wood posts :)

My mission base is a flat 3x3, 18 wood floors and 12 wood walls placed on 16 wood posts to start. I found like you that upgrading directly to concrete the ceiling will not be supported in this configuration. The solution I found was 12 more posts around the walls. Works fine that way.

So the result is 9 wood floors 3x3, 12 concrete walls, 12 wood posts around the exterior walls, with 9 concrete floors for a roof. All supported on my 16 ground wood posts...which could be cut back to 12 ground posts with the middle four spots clear if I cared to.

Usually have it up and running within 90 minutes, the hard part is finding 450ish silica.

It's good to know that wood posts work just as well.

Yes, thanks Rekal.
I did put wood posts ground to floor, but not floor to roof.
I will do so and test it tonight.

Just put some pillars to make the thing stronger... with wood floor, you can esealy put concrete walls and roof.. Just put some wood pillars :)

support pillars and foundation pillars if your building floor isn't flush on the ground

So I tested it with wood pillars everywhere from ground to roof... It collapsed! I had just enough time to press Y to not loose my concrete roof.
Maybe it has to do with last update ?
In my last mission (before update), I could build stone and upgrade it to concrete without issue.
Now, to upgrade to concrete I had to put stone pillars from ground to floor. And not just one or two, but almost to every concrete floor slabs, I had to put stone pillars.
This is the first time I have difficulties with concrete construction!

And I edit to say that my concrete slabs are not above the ground but flush on the ground. So I'm confused.

Really depends on how you're building your place. As I said, posts on the walls works for me but I always elevate the floor so any slope is not an issue.
