The Barricade is the only one of these buildings with a real price: its 10 levels cost 195.12M Meat and take about 14 days, and the last one waits for Furnace 30. A Shelter, the Cookhouse and the Clinic each reach level 10 for under 300K Wood and less than three hours of building, and their Automation level then costs more Wood than all ten levels before it.
All times are base build time, before any Construction Speed bonus.

The Shelter row is for one of the eight Shelters, which share one ladder: all eight take under 14 hours together. The Cookhouse and the Clinic are near twins, with the same build time; the Clinic's level 1 costs 25 Steel instead of Wood, the only Steel in this group.
When each building opens
| Building | Opens at |
|---|---|
| Shelter 1 | Furnace 1 |
| Shelter 2 | Furnace 1 |
| Shelter 3 | Furnace 4 |
| Shelter 4 | Furnace 5 |
| Shelter 5 | Furnace 6 |
| Shelter 6 | Furnace 7 |
| Shelter 7 | Furnace 10 |
| Shelter 8 | Furnace 10 |
| Cookhouse | None |
| Clinic | Furnace 4 |
| Barricade | None |
Shelters 1 and 2 open at Furnace 1 and the rest follow the Furnace, the last two at Furnace 10. From its opening level on, every Shelter, the Cookhouse and the Clinic need the Furnace at the same level as the upgrade.
The Automation level
The Shelters, the Cookhouse and the Clinic each have one more step after level 10, the Automation level, which needs Furnace FC1 and takes 2 seconds. It costs 260K Wood for a Shelter, 187,875 Wood being what levels 1 to 10 cost together, and 390K Wood for the Cookhouse or Clinic, against 273,765 and 273,730. The totals above leave it out.

Level 1 is free. Each later level waits for a Furnace level, spread from Furnace 7 to Furnace 30, so the Barricade is upgraded alongside the Furnace rather than in one go. Levels 9 and 10 cost 136M Meat and about 9 days between them, 70% of the Meat; Barricade Durability goes from 1,000 to 35,000.

The requirements follow Shelters 1 and 2. Every other Shelter costs the same, but its levels below its opening Furnace level all need that Furnace level.

The Clinic matches the Cookhouse from level 2 on, but its first four levels all need Furnace 4.
