When Matthew was 2 years old, Rob built him a "fort" for his birthday. Over the years, it has been played on by my children and their friends. A few weeks ago we were sitting in the backyard talking about what we should do for Andrew's 11th birthday. Matthew mentioned that he always wanted to build on to the "fort" and build a real tree house up in the oak tree. So it was decided! Matthew (with Rob's help) would build a tree house for Andrew's 11th birthday. Their was much discussion about the design and engineering. Geometry and Physics were involved! Here are a few photos of the project. Thank you Matthew....big brothers rock!
