Bob Vila heads to Cape Cod in the dead of winter to watch over the construction of a custom, high-tech greenhouse. The design and construction of a new addition to the front of an existing house afforded the creation of this conservatory and of a new front entry pavilion that features a mahogany pergola supported by limestone columns.
