Identify the resource you actually lack
Stone and masonry points play different roles in the documented construction chain. The quarry provides the raw material, while the mason's guild uses that material to produce masonry, so a missing point balance can originate earlier than the building project where you notice it. Start by identifying whether the problem is absent stone, stone that has not reached the guild or masonry production that is not being supplied.
This distinction makes the first investigation more precise than simply adding another building with a construction-related name. If the guild has no stone, the missing input deserves attention before you expand the processing side of the chain. If the question is about the balance displayed for construction, the construction points guide explains how the guild's output differs from both raw materials and free carpentry support.
Establish quarry supply first
The official FAQ identifies the stone quarry as the source of stone. Use the map and the current production information to establish where your county's usable supply comes from, rather than assuming that the starting region necessarily contains a nearby deposit. The collected material does not establish that every map offers the same convenient source, so a plan should follow the resource location you can actually identify.
Once a quarry is part of your plan, connect its role to a specific consumer or exporting region. A resource source is useful because it supplies another part of the county's economy, not simply because its building appears on the map. Following that purpose helps determine whether you are checking production at the quarry, delivery within a region or an import route serving a different region's construction needs.
Supply the mason's guild
The researched processing step is stone supplied to a mason's guild for masonry points. Treat the guild as a consumer of an input, using the same production-chain reasoning that applies to other materials and workshops. The important question is whether stone reaches the production location that needs it, rather than whether a stone source exists somewhere in the county without a working connection to that location.
Inspect the relevant material supply and point information together when construction is blocked. The construction overview describes tooltips that expose production locations and material storage, giving you places to compare the expected chain with what the interface shows. That comparison helps keep an empty masonry balance from being mistaken for an unrelated shortage of logs or an equipment problem in another settlement.
Recognize when you need an import
If the stone source you intend to use is in another region, local supply and inter-region trade become separate parts of the task. The importing region still needs its own processing relationship with the mason's guild, while the exporting region needs a way to deliver the raw material. Planning both sides prevents a receiving guild from being treated as a substitute for a transport route that has not been established.
Name the exporting region, receiving region and selected good before opening the route setup. This keeps the investigation tied to stone, rather than to another product the same regions may already exchange. The trade routes guide covers the Trade interface and the market or port infrastructure that supports those exchanges, leaving this page focused on what makes the stone supply a distinct construction question.
Use downstream raft routes in the demo
The official FAQ confirms that stone requires river transport between regions in the demo. Demo rafts travel downstream, so the river's direction is part of the supply requirement whenever the stone source lies outside the receiving region. A port at each end does not by itself establish that a route can move stone in the direction your construction chain currently requires.
Check the location of the stone-producing region relative to the intended destination before committing to an import plan. If the material would have to travel upstream, the downstream-only demo rule is a specific constraint that another ordinary road does not remove. Do not use the announced two-direction sailing capabilities of Early Access as evidence that the same transport is already available in the demo version you are diagnosing.
Keep the river restriction in its proper scope
The collected transport restriction applies to trade between regions. It should not be expanded into a claim that stone can never move locally by any road or that every stone consumer must occupy a riverbank. When you describe the problem, state whether the source and consumer are in the same region before applying an inter-region rule to their connection.
This is also why a county-wide view can conceal the actual place where supply stops. Stone may be part of an exporting region's production while the receiving region still lacks the delivery needed by its mason's guild. Follow the material through each regional boundary and processing step, rather than using the existence of a quarry as proof that every region's construction system should already be supplied.
Diagnose stone delivery before replacing buildings
A focused check moves from the blocked masonry requirement to the guild, then to its stone supply and the quarry or exporting region behind that supply. If the source is external, include raft ports and downstream direction in the review before changing the processing buildings. This is a practical diagnostic sequence, not a promise that a particular map will always have a route meeting the same conditions.
After addressing the connection, return to the original consumer and the relevant construction display. A quarry, a transport route and a guild each answer a different question, so checking only one of them can leave the original shortage unresolved. Keep the good's identity visible all the way through the chain, especially if nearby settlements are producing other construction inputs that cannot stand in for stone.
Plan further development around the complete chain
The useful planning unit is quarry supply, appropriate delivery and masonry production, rather than the quarry alone. That complete chain explains why a stone problem can appear while you are expanding infrastructure even though the missing raw material originates in a different part of the county. It also gives you a specific reason to investigate transport before spending attention on an unrelated settlement upgrade.
For the opening county, the beginner guide explains why food, logging and carpentry deserve attention alongside later material needs. For a settlement whose growth is blocked, the upgrade guide separates consumption requirements from construction supply and version limits. Keeping those questions distinct lets stone remain a clear resource-and-logistics problem instead of turning it into a vague explanation for every delay in development.
