Cutting Out the Windows

The tiny house has been sheathed and screwed completely! The windows are now covered by plywood and only visible from the inside by the outlining frames. In order to cut them out without missing the mark (and cutting random holes in the side of the house) I will need some guidance.

From the inside, I drilled a series of holes outlining the window. From the outside I connected the dots with the help of a straight edge. This gave me a scribe line indicating where to cut with the skillsaw. 

The depth of cut was set to 1/2" which is slightly deeper than the sheathing we used (15/32"). This will let me cut out the window hole without damaging the framework of the walls.

Once the line is cut, sheathing screws are set around the frame of the window. I waited to put these screws in because the saw would be damaged if it hit a metal screw along the cut! Now that the sheathing is scribed, cut, and screwed; it is time to remove the window panel and open up the window opening.

A three pound sledge hammer works wonders! I simply bash the cut wood from the inside and from the outside along the edge next to the cut. After a few hits, the panel will fly out of the hole and come crashing into the ground (make sure no one is standing around when you do this!)

The rough edges can be smoothed off by hitting it with the hammer again!

This works well on windows with no obstructions, but what about the windows near the rafters?

The skillsaw didn't fit under the rafter. This section of the cut was skipped while all the other areas were cut free.

A series of holes was drilled to weaken the wood in this area, then the panel was bashed out of the hole with the sledge hammer!

Using these techniques, all the windows were opened up. All this natural light transformed the tiny house from a wooden box to a home!
