Quick Guide
  • Starter cottage duct layout: begin with one short main route before adding any branches
  • Connection rule: every duct section must align and face the intended airflow direction
  • Test routine: run an airflow test after each structural change, one change at a time
  • Corner checks: inspect both sides of every turn before extending the route
  • Expansion order: main path first, then verified branches, then visual polish

Why the Starter Cottage Layout Works

The starter cottage duct layout is the recommended first project in Ductworks because it uses a small, inspectable footprint. Instead of filling the build area with ductwork, you create one compact route that serves a cottage-scale space, confirm that air travels through it, and only then expand toward a fuller HVAC arrangement. This staged workflow keeps every problem traceable to a single recent change.

A cottage layout typically contains four functional zones, each tied to a distinct part of the duct route:

ZoneDuct RoleCommon Mistake
Source areaWhere air enters the systemPlacing the source before planning the route
Main corridorPrimary straight duct pathBending the corridor before the main route works
Corner transitionsTurns toward each roomMisaligned openings on either side of a turn
Room outletsEnd points receiving airflowAdding outlets before branches are tested
Keep It Compact

A smaller first build makes layout problems easy to spot. Treat the starter cottage as a learning tool, not a showcase piece, and expand only after the compact system behaves as intended.

Starter Cottage Duct Layout: Step-by-Step Build

Follow this sequence when building your first cottage duct system. Each step ends with a verification point, so a failure always points to the most recent change.

1

Plan the route before placing parts

Decide where air begins, where it travels, and where it ends. Sketch a main path from the source through the cottage corridor toward one room outlet. Reserve space for future turns and branches.

2

Place the main duct sections

Use the building controls from the bottom control bar to create a continuous straight line of ductwork. Keep adjacent sections aligned and readable rather than tightly packed.

3

Add the first corner transition

Turn the route toward the target room. Inspect both sides of the corner: the incoming and outgoing sections must meet the transition correctly, with openings facing the airflow direction.

4

Test the airflow

Run the available testing or simulation controls. Follow the route from the source toward the destination and confirm air travels the full path before adding anything else.

5

Add branches one at a time

Once the primary route works, add branch sections toward additional rooms individually. Retest after each branch so any behavior change has a clear cause.

One Change at a Time

If you add several untested branches at once, airflow problems become difficult to diagnose. Change one part of the layout, test, then continue.

Three Cottage Layout Variants

Once the basic starter route works, compare these three variants. Each isolates a different design decision, which makes them ideal small-case learning exercises.

Straight Route

  • Simplest possible layout
  • Every connection easy to inspect
  • Best for learning placement basics
  • Ideal first test system

Turned Route

  • Adds one or more corners
  • Teaches transition alignment
  • Serves rooms on opposite sides
  • Test each turn individually

Balanced Branches

  • Splits the main path
  • Distributes air to multiple rooms
  • More complex troubleshooting
  • Add only after the main path works
VariantBuild DifficultyAirflow VisibilityBest For
Straight Route★☆☆☆☆HighFirst build and connection practice
Turned Route★★☆☆☆MediumLearning corners and transitions
Balanced Branches★★★☆☆LowerExploring distribution behavior
Compare, Don't Guess

Run the same test on each variant and record what changes. Comparing a direct route with a turned route, or a single branch against balanced branches, shows how structure affects airflow without guesswork.

Troubleshooting Common Layout Errors

When air fails to travel through your starter cottage duct layout, inspect these five failure points in order:

ErrorSymptomFix
Disconnected sectionsAirflow stops mid-routeRealign adjacent sections until they meet
Reversed directionRoute looks connected but air misbehavesRotate the affected section and retest
Misaligned cornerAirflow stops at a turnInspect both sides of the transition
Untested branchNew branch interrupts the pathUndo the branch, retest, then re-add
Overpacked layoutHard to inspect connectionsSpace sections out for readability
Review the Latest Change First

When a test fails, the cause is almost always the most recent structural change. Undo or adjust that change before rebuilding the whole system.

Build Goals Checklist

Complete these milestones to graduate from the starter cottage to larger HVAC projects:

Starter Cottage Milestones:

  • Plan and place a working straight main route
  • Add and verify one corner transition
  • Pass a full airflow test on the main path
  • Add one branch and retest successfully
  • Compare straight, turned, and branched variants
Multiplayer Review

In multiplayer sessions, assign one player as the final reviewer before extending the system. A layout planner, builder, and tester role split keeps shared cottage builds easy to manage.

FAQ

Q: What is a starter cottage duct layout in Ductworks?

It is a compact first build: one short main duct route serving a cottage-scale space, with corners and branches added and tested one at a time. It is the recommended way to learn how placement, direction, and connections affect airflow.

Q: Why does my duct route look connected but airflow does not work?

Check the direction of each section first. A visually connected route can still contain a reversed section or a misaligned corner. Rotate the affected section, then run the airflow test again before changing other parts.

Q: When should I add branches to the layout?

Only after the main path passes an airflow test. Add one branch at a time and retest after each addition so any change in behavior can be traced to a specific connection.

Q: Can I build the starter cottage layout with friends?

Yes. In multiplayer, divide roles into layout planner, builder, and tester, keep the first shared build compact, and have one player act as final reviewer before extending the system.
