The number 2 project in
our queue was completed this weekend, due to the efforts of Dad, Mom, Uncle B, and Aunt M. Why the "The Castle?" That's O.'s word for it, and he defends it with enthusiasm.
We began with this: a pile of treated lumber and recycled deck wood, a wily three-year old, obliging parents/grandparents/aunt/uncle, and a dream.

A couple of days before the project began, a rare (we hope) series of
earthquakes occurred. Minimal damage in our area, fortunately. The most severe quake in the series kicked around the wood pile a bit, shown below. Must have been the midwestern-raised in me again, but I was impressed.

We lucked out with the weather, but early afternoon showers forced the first steps of the project indoors. Here's J., Dad, and Uncle B. assembling the base.

And here's Mom, documenting the process.

The next step was to attach the vertical beams. The horizontal 2x4s acted as temporary support, by the way. Aunt M. is shown below, holding it and us together.

We learned that power saws and naptime don't mix. O. came outside to express his displeasure at the racket. O. quickly realized that the result of his noise is to his benefit.

The floor of the deck was installed next.

It was clear the deck is the best place to be. We basically built it around O., with Aunt M. for comfort/safety/entertainment.

A test run of the slide. Uncle B. later mounted about a foot off the ground, which makes it easier to climb into at the top. O. can land on his feet, which gives him a good running start. I think a swimming pool will reside at the end of the slide this summer.

Uncle B. seems satisfied with the climbing wall installation.

As you can see, O. needs a little help to climb into it yet, but he'll learn. Kids need goals.

The finished product, or at least finished for now. Plans for future modifications and improvements were tossed around, including a roof, some seating for the sandbox below, a bucket and pulley, and swing.
