Introduction: Build a Log Cabin Playhouse for Under $300
I noticed that my 3 year old Son always gravitated toward the playhouses whenever we went to a big playground. So, I put Playhouse on my list of things to get for him.
Yeah well, after shopping around for a while I found that a Playhouse of any decent size was $1200 for a striped down, 4'x 6' box. Then there was the Log Cabin one that I thought was really cool but it was $3700, marked down from $4200 because it was a floor model!
Then came my inspiration, my Neighbors put in a Stockade fence this spring and were resting the panels against their garage until they used them. I walked outside, glanced over and thought... Dang, those look like the side to a log cabin! And so my planning began.
DISCLAIMER: This structure will be as durable as you make it. If you do a crappy job and it falls down on your kids head it's not my fault.
My Son has been using this playhouse almost every day, even when it's raining. When I pick him up from daycare all he wants to do is go into his playhouse, He has even eaten his dinner in there more than once. On several occasions I have had to carry him inside screaming in order to put him to bed.
1. My Son for some reason has been leaving the front door open and he runs into the playhouse and bounces off the back wall. As a precaution I decieded to pre-drill and screw the slats on the back wall to the stringers. He didn't knock any slats off but I figured just in case.
2. My dog has been digging on the side of the playhouse and sniffing through the floor of the playhouse. I looked under and didn't see any animals I would suggest that you apply some metal mesh around the foundation prior to putting on the walls.
3 Year Update
I noticed that it's been 3 years since I created this playhouse so I decided to take a picture of it in it's current state. It's had a lot of snow on the roof over these 3 years and a lot of abuse from my now 6 year old Son and my 2 year old daughter. Picture 2 shows it's current state taken exactly 3 years from the original. I think I need to stain the floor again, but the rest held up well.
The sunflowers were built from that same Neighbors old metal fence posts and the cut offs from the wall panels. The center is actually a piece of plywood covered with left over roofing material.
Step 1: Stuff Needed to Buy or Have
You will probably want at least two people to move the panels around and lift them in place. I am a pretty big guy so I just tipped them up the long way, leaned them against my back, grabbed the top of the 8' section, leaned forward a little, and carried them where I wanted them.
Time: This took me 4 weeknights (6:30pm - 8:30pm) to level the ground for the floor and one very long Saturday and Sunday to finish the build.
6 - 6' x 8' stockade fence with 2x3 supports
4 - 4 x 4 x 6' Treated timbers
2 - 2 x 4 x 8' Treated lumber
2 - 2 x 4 x 8' Lumber
1 - 2 x 3 x 8' lumber. (As straight as possible)
1 - 1 x 3 x 8' lumber
1 roll of Roll roofing
2 - 1lb Box of 1 1/4" Deck Screws
1lb Box of 3" Deck Screws
1lb Box of 7/8 roofing nails (left over from another project)
3 Gallon of Deck stain (2 light cedar, 1 dark green)
2 Packages of Cedar shims
Total Cost for me = $268.42
Terminology used in this instructable:
Slats = the part of the fence panels that look like the log
Stringers = the three 2x3x8' long boards on the fence panels that keep all of the slats together
Make all of your cuts with the circular saw from the inside of the panels to reduce splintering that can be seen from the outside. This can sometimes be difficult but take your time and it will look a lot better
Step 2: Foundation
If you are willing to spend some more money and time, I would suggest that you dig out and lay down some crushed stone under the 4x4 supports. I didn't have any extra of either so I just made the dirt level and tamped it down as much as I could.
Pick the location for your playhouse.
It should have enough room around it that it does not get in the way of other things like a swing set or kiddy pool. My back yard is Freaking tiny so the only location I had available was either behind the garage where no one can see it, or in the back corner where a raised flower bed once was. My Wife and I decided on the back corner. This made my life a little more complicated because I had a LOT of leveling to do and I will have to move the swing set back about two feet for safety.
Cut the 4x4 supports to length.
Measure the outside distance of the two outermost stringers on your stockade fence panels. Mine were 56 1/4" so that is how long I cut my 4x4's.
You need to position the 4x4 floor supports so they will fall directly under the stringers in the wall panels. Using the 2x3x8' lumber that you purchased set it along one of the Fence panels and mark where each of the support piece are. This will then be used to position and level the 4x4 floor supports.
Level, Level, Level, Level,
Take a look at your location and determine the lowest point. You will need to start from there. Tamp that ground down as much as you can then place and level the first 4x4. This was the front for me
I found it easiest to then place the 4x4 for the back and level that.
Once you have leveled the Front and Back supports you can then start to level the center two.
Stabilize the base
Position the two 2x4x8' pressure treated lumber on the 4x4 supports so they fall in between where the supports from the fence panel will fall. Screw the 2x4's to the 4x4 supports to prevent them from moving while backfilling.
Fill in with any extra dirt to stabilize the 4x4 floor supports. Leave 1 to 2 inches of the 4x4's above ground level to allow air movement under the playhouse to prevent rotting.
Step 3: Cutting the Panels
Select the nicest fence panel you have to use for the floor. Remember, your kid will be crawling, rolling, and laying on this floor
Support the fence panel up off the ground using the cut off pieces of 4x4. Make sure you have the stringers facing up, and that the 4x4's are inside the outermost stringers.
Using your circular saw cut along the outside edge of each outermost stringer.
Fit the floor but don't secure yet
Lay the newly cut floor panel onto the 4x4 floor supports and adjust the 4x4's to exactly fit the floor panel.
Cutting the Front and Back wall panels to size
Measure the front and back wall panels so they will be six feet high. You can deviate from this slightly so you end with a full width slat.
Snap a chalk line and make the cut.
You must now cut the front and back to the proper width. You only want to have a slight overhang past the outside stringers to cover the slats on the side panels. From the back of the panels, measure out the thickness of the slats (3/4 for me) from the outside edge of the outer stringers and snap a chalk line.
Cut along that line from the inside of the panel to reduce splintering.
Measure and mark the top center of the front and back panel. Measure and mark five feet from the outside bottom edges of the Front and back panels. Connect those three points with a chalk line and snap your mark. Cut along that mark to set the roof pitch.
Cutting the Side Walls to size
Mark the height of the side walls to the same height as the lowest point on the front and back walls, should be around five feet. Mark this height with a chalk line.
The side wall panels must have a larger overhang than the front and back in order to cover the corner where you screw the end stringers together. For me this was an overhang of 2 1/4 inches. Mark that overhang on the edge of each panel with a chalk line and as always make the cut from the inside of the panel.
Cut the Roof panels
This would have to be the most complicated and labor intensive part of this build.
You will be removing each of the stringers on the last fence panel and screw them to the opposite side of the panels in the needed locations.
On the front panel, measure the distance from the top point to the outside edge along the angle. Transfer that measurement to where one of the stringers must be on the roof panel. The other stringer should be two inches in from the top edge. This is to prevent the top stringers on the roof panels from binding with each other. Use the 2x3x8 board for the fourth stringer. (During Layout, make sure you use the point top of the fence panel for the peak of the roof. This will allow you to use the most of the panel and hide the pointy parts with the ridge cap. Also, if you have any leftover material that you need to trim off, make sure you take if off the pointy end "about 1 inch for me") Remove and reposition only one stringer at a time to keep the panel as straight as possible.
Once all stringers are in the correct location, Measure and mark the center of the fence panel with a chalk line. Cut the fence panel into the two roof sections.
Step 4: Mark and Cut Windows and Door
You now need to select the locations of the windows and doors
For my setup I made a 24inch wide by 48inch high door since that fit almost perfectly between the stringers.
Cut the window out all the way but only cut out some of the door. If you cut out the whole door the front panel would be too unstable while you are moving it around.
Step 5: Stain Everything
Now that the majority of your pieces have been cut you should stain and seal them prior to assembly so the playhouse will last as long as possible. Maybe even your grandchildren will use it. Or, you can use it as a shed at a later point. Make sure you seal the front and back of every piece including the floor panel.
Step 6: Secure the Floor and Walls
You will most likely have to use some of those Cedar shim's since the stringers will most likely be a little thinner than the 2x4 treated lumber already there.
Put one 3" Screw directly through the floor panel stringers and shims into each of the 4x4's.
Setting the first wall
Screw one of the 2x4's into the side of the floor and part way into the other end of the 2x4.
Lean the back wall up and secure it with the 2x4.
Make sure the back panel is perfectly positioned since all other walls will key off this one. Screw the back panel to the floor with 3" screws by screwing at an angle through the bottom edge of each stringer "two screws each, pre-drilling through the stringers will make this easier".
Now just lean the side wall opposite the 2x4 support up, kick it so it is firmly against the back panel and screw it into place through the pack panel into both stringers.
Secure the bottom of the side wall in the same manner as the back.
Remove the 2x4 support and add the other side wall.
Now cut the remainder of the door out and screw it into place from the front.
Step 7: Put Up the Roof
Lift the first roof panel up and onto the playhouse. Make sure you have your drill and a few screws very handy because this won't stay up there on it's own while you go get one.
Screw down through the roof stringers into the stringers of the front, back and sides with 3 inch screws.
Step 8: Cutting the Door and Trim Pieces
Now to cut the door, shutters and fascia boards.
I'm not going to give you measurements for this because they will most likely vary per playhouse. Plus you should measure prior to cutting out so you know you have the exact spaces.
Step 9: Front Porch
Now to cut and assembling the front porch.
The front porch and railing will support the roof overhang and also keep adults from walking off the side of the front porch, remember, the side of the front porch roof is only five feet high... remember that!!!
This is a lot of work but it really makes the playhouse.
I decided later on that I would apply slats to the two outside edges of each 2x4 post because I didn't like the looks of the generic 2x4 posts. I think it looks a little chunky now but better than before.
Step 10: Installing the Roof
Now to cover that gap at the peak in the roof with a fence slat.
Install for lack of a better word (Cleat) inside the front fascia, and also apply one to the center stringers on the front and back wall. The cleats should be flush with the top of the roof peak.
Now cut one fence slat that will go from the cleat on the front fascia to just past center of the front wall cleat. You need to make this cut at a 45 degree angle. Then cut another slat from the back wall cleat flush with the back of the roof, ending at the front wall cleat, again making a 45 degree cut so the two piece of the ridge cap will sit perfectly flush.
Now just screw the pieces of the ridge cap on and you have a nice rounded top to the peak of your roof.
I precut all the sections of roll roofing to 8 feet 1 inch. I then slid them into place doing the side panels first. I nailed every 4 slats about 8 inches from the edge leaving any overhang on the back of the playhouse.
Once both sides were up and nailed on, I rolled on the center roofing and nailed that down about 2 inches from the peak and then about 4 inches from the edge again every 4 slats.
I was told that after the first couple hot days the roll roofing will flatten itself out.
Step 11: The Shutters
The shutters are for more than just looks. They actually secure all of the little pieces of siding that are left when cutting out the windows.
each shutter is made from six individual pieces. Four that are 24" long and Two that are 8" long. Again, stain all sides of these pieces prior to installing.
Clamp the first long piece along the edge of the window ensuring it will overlap top and bottom onto full length siding slats. Now, go inside. You need to pre-drill all of the small slats since they WILL split if you don't. Then just secure the first part of the shutter from the inside through each slat.
Now, the second long piece of shutter is just for looks, and it is usually over one of the stringers so you won't be able to screw it on from the inside. Just secure the piece with two screws. Pre-drill them and locate them under where the shutter cross pieces will go.
Then pre-drill and screw in place the cross pieces from the front.
