Episode Overview
The episode begins atop Great Blue Hill, where viewers are treated to breathtaking views from the historic weather observatory, established in 1885. The crew is hard at work, removing planks from the front section of the barn as they prepare to convert it into a garage. They discover various areas suffering from rot and substandard construction. Meanwhile, forms are set up for the new workshop's concrete foundation. Landscape architect Tom Wirth examines the site’s difficulties, particularly the inadequate access to the house's front. He finds inspiration in historic photos of the former gravel drive, proposing a similar design. Insulation expert Graeme Kirkland shares findings from a blower door test, revealing that the house's interior air changes 11 times every hour at a simulated wind speed of 15 miles per hour.
