How To Build A Second Floor In Raft

In this guide, we will look at expanding your Raft by building a second floor on top of the base level you start off with.

Building and expanding are necessary for surviving in a game survival game like Raft and in order to be efficient, you will need to be creative with your expansions. In this guide, we will look at expanding your Raft by building a second floor on top of the base level you start off with.

How To Build Second Floor in Raft

You start off in Raft on a small piece of wood, and it is up to, you to survive in the vast and endless ocean. There will come a point when the small piece of wood won’t be able to keep you afloat and you will need to expand.

The first instinct will be to expand the area of the raft which is usually the first thing a player will do when they are expanding their raft, but there will come a point when you think that I have expanded the width of the raft enough and that’s when you will get the idea of going in the upwards direction.

You will need the following items to build the second floor.

  • Floor (any kind)
  • Nails
  • Wooden Pillars

You can make a floor using planks which will depend upon the type of floor you are making. Nails can be crafted from scrap and wooden pillars can be crafted from 2x planks and 2x nails.

Building a second floor is easy just remember the keyword “support”. Anything you place will need something to stand on, something to support it. You can build a second floor using the flooring of your choice.

Firstly, you will need to put up walls on top of which the second floor will stand, and then you can start placing the floor. You can start by placing the floor along the walls first.

Once you have done that and you need to put the floor for the middle section, you won’t be able to because nothing is supporting it. You will need to place support such as a wooden pillar and then you can place more floor around it.

Keep repeating and you will have your Raft’s second floor ready in no time. A tip is that place the wooden pillar not exactly underneath but at a point where several floors meet.

A common mistake that players do is placing pillars close to each other which take up space and resources. Remember to place a single pillar on each corner of the floor. That way, a 4×4 floor will only need four pillars.

Just keep in mind that the higher you build, the more time it will take you to navigate the base floor in case of emergency and you will have to rely on ziplines to travel around.

How To Build Second Floor Without Pillars

If you want to build a floor without pillars, you can use walls as pillars. If there is a wall of a room running on your raft, you can use that to act as a pillar for your second floor.

In the same way, you can use windowed walls. You can furthermore use sloped roofs which will keep on going without collapsing.

There is also a glitch in Raft that you can exploit to build a floor without any pillars. What you do is first make a second floor with all the necessary pillars you need. Then install overhead lights between each pillar in a row. Finally, remove all of the pillars and you will see that the floor stays put. The overhead lights, for whatever reason, glitch and hold the second floor in place.

You can also use triangle parts to build a roof. Then remove the pillars.

The following image taken from the Steam community is how the no-pillar floor glitch works. Just note that the developers will eventually update Raft to remove the glitch.

Lastly, you can use mods to build floors without pillars.
