Simple Tiny House Loft Ladder

Introduction: Simple Tiny House Loft Ladder

About: I'm an applied mathematician and an enthusiast for green power, the developing world and solutions to complex problems. There's nothing more fun than finding a cheap and effective solution!

My folks recently built themselves a tiny house on their property for guests with a loft to maximize their 240 sq. ft of space. But, in the mix of things they hadn't gotten themselves any stairs to the loft yet. Sadly when I came to visit I was unable to sleep up in the loft. But that was quickly remedied. And now they have stairs thanks to a few hours and the help of some basic tools.

Step 1: Tools and Supplies

You'll need the following supplies:

  • 2 - 2"x6" 8' lengths (for the ladder frame)
  • 6 - 2"x6" 2' lengths (for stairs / runners)
  • 6' of quarter round oak (pine would work fine too)
  • Some 1 1/2 " wood screws
  • Some 4" wood screws


  • Circular saw
  • Jig Saw
  • Drill / Driver
  • Speed Square
  • Pencil

Step 2: Determine the Angle of Rest

Start with one of the 8' sections of 2x6 and lean it up agains the loft from the floor.

Meaure the angle that the 2x6 makes with the perpendicular to the floor.

Or, put more simple, figure out what angle you'll need to make the notch which fits onto the lip of the loft. This angle is important as all steps, end cuts and the lip notch will all be tilted at this angle.

Using a speed square I determined that 15 degrees was not too steep and yet provided a nice compact set of stairs.

Mark where the lip of the loft will meet the ladder frame. Mark out a square here at the appropriate angle (15 degrees) and using the jig saw cut out the notch.

Step 3: Trim the Ends

In order for the ladder to set flush with the floor, the ends need to be trimmed at the previously determined angle. In my case this was 15 degrees. A quick mark with the speed square and cut with circular saw was all it took.

I went ahead and made a similar cut at the top of the ladder frames for aesthetic appeal.

Step 4: Mark Off Your Steps and Install Quarter Round Supports

Start by marking the first and last step placements on one of the ladder frame 2x6's. It was helpful to simply position the 2x6 where it was going to go, pretend to take a step and mark where it felt comfortable to step first.

Likewise you want to envision stepping off the ladder at the top. It's really much easier if you'r last step is the loft platform itself. I suggest making the last ladder step slightly below the loft cutout lip (on the ladder frame).

Then, measuring out the distance between the first and last steps mark off where the additional 3 or 4 steps (or more) will be placed.

Now, using the speed square, mark a line at the correct angle and position along the frame for where the step will be placed. For me it was again 15 degrees.

Cut 5" supports out of the quarter round. I used oak for 2 reasons: I had it on hand, and it's super solid.

I had to drill pilot holes in the quarter round, no problem there. Screw them into the ladder frame with the 1 1/2" wood screws.

Step 5: Attach the Steps

Using the 4" screws from the side of the frame into the short end of the step attach each step to one side of the ladder frame.

And then the other.

This would have been difficult with one person. So I got my pops to help me out here.

The steps should sit flush on the quarter round for vertical support.

Step 6: Install at Tiny House Loft

Finally, lug your beast of a ladder to the tiny house and instal where it makes the most sense. If you leave it free, you can slide it from side to side.

But, for safety sake you may want to at least somewhat secure the ladder to the loft so that halfway up your climb you don't fall over backwards, ladder and all.

All in all, a good looking, simple and effective ladder!

    Question 12 days ago on Step 2

    Your ladder is exactly what I've been looking for! The loft in my little building is 8' from the floor. I can get a 2 x 6 x 10 and trim it much above the loft floor should I have my ladder supports extend? Or maybe I should say how far from the end of the board should I make the notch? Might be a personal preference but I thought I'd check! Thank you!

    I like your plan. Following the steps in my head it would seem better to trim the bottom first (@15%) before locating the notch for the top. Otherwise the ladder would drop a few inches after you trimmed the bottom, no?

    True... the perfect fit would be best achieved by trimming the bottom first. And then measuring the notch height and cutting.

    I think I took the lazy man's approach and measured the notch height and adjusted it for what I would be removing on the bottom with an additional 1/2 inch "error" room to be safe.

    Well regardless of which should be done first, it's definitely the plan I will use for my small cabin. Thanks for sharing!
