Use Construction inside the correct town
Build a Carpenter’s Workshop, unlocked through The Giant Owl. With the workshop in town, open Construction, select the existing building and inspect its target upgrade and materials.
The workshop’s Workbench also provides construction access. Check that the bench is still inside the intended town boundary; placing a bench anywhere does not establish access to every town’s upgrades.
When Upgrade is missing or greyed out
| Check | Action |
|---|---|
| Blueprint | Read the target level’s required quest or unlock |
| Workshop | Make sure this town has the required Carpenter’s Workshop |
| Materials | Check accessible Material Storage and the target upgrade cost |
| Worker | Confirm a Carpenter is available for construction |
| Job mode | Check that the Carpenter is constructing rather than doing another job |
Read the actual disabled-button message where available. This checklist covers common prerequisites; it is not a universal error code for every building.
Workshop milestones are not every building’s requirements
Virgil’s Poem unlocks Carpenter’s Workshop Level 2. Profane Artifice unlocks Level 3. Other buildings can have their own unlocks, costs and profession caps.
Version 0.26.1 added a Carpenter Repair job, and 0.26.1_3 set Constructing as the default. Having a Carpenter citizen does not guarantee they are currently doing the construction job you need.
See Brick Oven if the upgrade is waiting for bricks, or moving buildings if the real problem is your town layout.
