Where should I build my base?

Small islands, the tip of a peninsula, and locations bordered by rivers or cliffs are the most popular picks because cannibals struggle to reach them. Open flat ground means raids can come from all sides, so lean on natural barriers. A waterside base also doubles as a water source.

What are the basics of log construction?

Chop trees for logs, open the build manual with the B key, and pick the structure you want to make. Stand logs vertically for walls and lay them horizontally for floors. Start with a small shelter and expand once you're comfortable; you can scale up to elaborate fortresses later.

How do I defend the base effectively?

The formula is "walls plus spikes plus funneled entry." Log walls stop the direct rush, and spikes shred anything that charges in. Instead of fully sealing the perimeter, leave one or two paths open and stack spikes there — cannibals naturally pile into the kill zone and you handle them efficiently.

Can Kelvin help with building?

Yes. Kelvin takes orders and will gather wood, haul logs to a specific spot, or stand guard. While you're placing structures, give him a "chop trees over there and pile them here" loop and your log supply is essentially automated. Construction speed typically doubles or triples.

Sons of the Forest Base Building｜Location, Log Walls, Spike Defense

Location Is 90% of Base Building

Where you build dramatically changes how easy the base is to defend. The rule is simple — use natural barriers wherever possible.

Small island in a lake Cannibals rarely cross water — the strongest defensive location in the game Tip of a peninsula Only one direction to defend, much easier to fortify

Land between two rivers Natural defense lines limit incoming paths Backed against a cliff or canyon One-direction defense is much simpler to manage

Middle of an open plain Full 360-degree defense burns through materials and time

A small island in a lake is the best early-game base candidate. Cannibals rarely make the swim, which essentially neutralizes night raids. Let Kelvin handle hauling materials across the water for efficiency.

Construction Basics

1

Open the build manual (B key)

Pick the structure you want and the log placement guide will appear in the world.
2

Gather logs

Chop trees with the axe. Felling speed jumps once you grab the modern axe.
3

Place walls, floors, and roofs

Stand logs vertically for walls, lay them horizontally for floors, angle them for roofs. The placement is intuitive once you try it.
4

Add doors and windows

Cut minimal openings for movement, light, and visibility.

Start with a small shelter (bed + fire + crafting table) and expand as needed. Aiming for a giant fortress on day one will leave you short on logs when night arrives.

Defensive Layout

Element	Role	Placement Tip
Log walls	Physically block intrusion	At least two stories tall so cannibals can't vault them
Spike traps	Damage anyone who breaks through	Concentrate them on entry paths
Gates and corridors	Balance access with defense	One or two only — not sealed, not wide open
Watchtower	Bow and gun firing position	Place where you can see incoming attackers

A fully sealed base is hard to breach but also a pain to leave and enter. The efficient move is to leave one or two corridors open and stack spikes there — cannibals funnel into one spot and you deal with them on your terms.

Combine With Combat

Once the base is solid, you still need to handle the cannibals who keep coming. For combat technique, see Combat and Cannibals, and for early-game progression see the Beginner Guide.

★Honest Take: The Satisfaction of Finishing Your Fortress

Honestly, the most rewarding part of Sons of the Forest is the long process of building your own fortress. Standing logs one by one, lining up spikes, and surviving the night raid you designed for — that tension and payoff is something other survival games rarely match. Lean on Kelvin to automate the grunt work and you can focus on the design itself.
