Treehouse Masters: Out on a Limb

On "Treehouse Masters," world-renowned treehouse designer and builder Pete Nelson and his team of craftsmen -- including his son Charlie -- create incredible homes and businesses in nature's canopy. Pete uses a combination of science and art to realize clients' sky-high aspirations of magnificent multibedroom treehouses with elaborate kitchens and bathrooms, or simpler, peaceful one-room escapes. Subtitled "Out on a Limb," this companion series takes viewers even further into the builds by updating previously aired episodes with additional footage and Pete's commentary.
