The Castle!
Now, for something different. What do you do with an "L-shaped" playroom that has ugly carpet? You make a built-in castle for the kids!
Our castle is incredibly strong (I've been up and down the ladders and watched tv from the rooftop) and was built out of 2x4s, mdf and PL premium. The door and shutters are from our reclaimed fence and Mom made personalized flags for our son and daughter. NOT REALLY FOR SALE!
