</>What does Master Builder do?
Building in Sons of the Forest is satisfying, but the log-chopping, hauling, and stacking can eat entire days. Master Builder turns all of that into pure creativity. With it on, every structure costs nothing to place and finishes the instant you set it down. No felling trees, no carrying logs across the map, no waiting — just picture the base you want and watch it appear. Ideal for designing sprawling fortresses, testing layouts before a survival run, or throwing up defenses the moment a raid rolls in. Works best in solo or offline play; in co-op, outcomes are decided by the host.

</>Common questions about Master Builder
What does Master Builder do in Sons of the Forest?
Master Builder lets you build any structure in Sons of the Forest with zero materials and have it finish instantly. Building is satisfying, but the log-chopping, hauling, and stacking can eat entire in-game days. Master Builder turns all of that into pure creativity: with it on, every structure costs nothing to place and completes the instant you set it down. There's no felling trees, no carrying logs across the map, and no waiting for construction to finish. You simply picture the base you want and watch it appear. It's built for designing sprawling fortresses, testing layouts, or throwing up defences the moment a raid rolls in.
Does Master Builder make structures both free and instant, or just one of those?
Master Builder does both in Sons of the Forest — it removes the material cost and the build time together. Normally a structure needs logs and other resources you've gathered, and then it takes time to construct piece by piece. With Master Builder on, the material requirement drops to zero, so you can place anything without collecting a single log, and construction completes the instant you set it down rather than needing to be built up. The two effects work as a pair, which is what turns building from a supply-and-labour chore into a pure design activity. You place it, it's finished, and you move straight on to the next piece.
Can Master Builder place any structure in the game, including big defensive builds?
Yes. Master Builder applies across the building system in Sons of the Forest, so everything from a simple wall to a sprawling multi-level fortress can be placed for free and finished instantly. That makes it especially handy for large defensive builds — you can ring your base in walls and spikes in seconds rather than spending days gathering and stacking logs. It's equally good for ambitious creative projects that would normally be impractical because of the sheer material cost. Because there's no resource limit holding you back, the only thing deciding what you build is your imagination and the game's own placement rules, not how many trees you've felled.
Is Master Builder a toggle I can switch off to build normally again?
Yes, Master Builder is a single on/off toggle in the ProjectMods launcher — flip it on for free, instant construction, and flip it off to return to normal building with real material costs and build times. There's no slider, since the effect is simply on or off. Because it's fully reversible, you can use it to block out the shape of a base quickly, then turn it off and finish the details the traditional way if you enjoy that side of the game. Toggling Master Builder doesn't alter or damage your save, so structures you've already placed stay exactly where they are when you switch it off.
When is Master Builder most useful in Sons of the Forest?
Master Builder is ideal for designing sprawling fortresses, testing layouts before a survival run, or throwing up defences the moment a raid rolls in during Sons of the Forest. If you love the creative side of building but not the log-gathering grind, it lets you focus entirely on design. It's also great for quickly prototyping a base plan you'll later rebuild the hard way, and for content creators staging an impressive location on camera. Works best in solo or offline play; in co-op, building outcomes are decided by the host, so free instant construction follows whoever is hosting the session.
