Exterior Deck Over an Interior Room


Building an exterior deck over an interior living space brings a unique set of challenges, the most prominent of all being waterproofing.  Our friends Peter and Richard asked us to rebuild their deck, which has been leaking for years.  While we were at it, we decided to upgrade the doors, and add a cedar shade arbor to promote comfortability during the hot months.  The waterproofing is a proprietary two-part liquid membrane that mechanically joins the wall waterproofing and door pans, creating a seamless, "one-piece" waterproofing system.

The result is a functional, cool and aesthetically pleasing exterior living space overlooking the bay that keeps the water on the outside of the house where it belongs.
