12×24 Tiny House With Loft Plans

by Ovidiu


This step by step diy woodworking project is about a 12×24 tiny house with loft plans. This is a more complex projects, so I decided to split in in several parts so that I can cover everything explicitly. The first step of the project is to build the floor for the tiny house using 2×8 beams and 3/4″ plywood sheets. Take a look over the rest of our woodworking plans, if you want to get more building inspiration.

When buying the lumber, you should select the planks with great care, making sure they are straight and without any visible flaws (cracks, knots, twists, decay). Investing in cedar or other weather resistant lumber is a good idea, as it will pay off on the long run. Use a spirit level to plumb and align the components, before inserting the galvanized screws, otherwise the project won’t have a symmetrical look. If you have all the materials and tools required for the project, you could get the job done in about a day.

Locate and dig the footing holes, excavating each hole 16″ wide to the required depth. Fill the first 8″ of the holes with concrete, in order to create the footings. Allow the concrete to set for at least one day.

Install a tube form on the footings. Make sure all the tube forms are aligned properly, before filling the hole around with earth. Tamp it down firmly. After every 6″ of fill, check that the form is vertical with a level.Install the anchors that will support the skids and allow the concrete to cure for a couple of days.

Make sure you read the local building codes before starting the project, to determine the depth of the footing, the distance you need to leave between them, as well as the other legal requirements.

Assembling the skids

Assembling the skids

Build the skids from 2×8 lumber. Fit 1/2″ plywood pieces between the beams. Add glue to the joints and insert 2 1/2″ screws from both sides. Align the edges with attention and make sure there are no gaps between the beams.

Fitting the skids

Fitting the skids

Fit the skids to the anchors. Use 3″ lag screws to secure the beams into place. Use a spirit level to make sure the skids are perfectly horizontal. Measure the diagonals and adjust the position of the beams until they are perfectly equal.

Assembling the rim frame

Assembling the rim frame

Build the frame for the tiny house from 2×8 lumber. Cut the components at the right dimensions. As you can see in the diagram, you need to align the edges with attention. Drill pilot holes and insert 2 1/2″ screws. Make sure the corners are square before inserting the screws.



Fit the rest of the joists to the floor frame (138″ long). Place the joists equally spaced, every 24″ on center. Use joists hangers to secure the beams into place. Check if the square are right angled before inserting the screws.

Fitting the flooring sheets

Fitting the flooring sheets

The next step is to attach the 3/4″ plywood sheets to the joists. Leave no gaps between the sheets for a professional result. Use 1 1/4″ screws to secure the plywood into place, every 8″ along the joists. Use tongue and groove plywood sheets, so that you don’t leave gaps between the sheets.

Fill the holes with wood putty and let them dry out for a few hours. Smooth the surface with 100-220 grit sandpaper and remove the residues with a damp cloth.

Top Tip: Apply a few coats of paint or stain to the components, to enhance the look of the project. Check out PART 2 of the project so you learn how to build the walls for the 12×24 tiny house.
