Well, about seven years ago we built the first half of our house and we've been using it as a weekend/vacation place. My wife retires in September so we're starting up again getting ready for finishing the build. I specifically didn't build the main living areas earlier because I wanted to be on site (I'm now 300 miles away). We're meeting with the architect later this month to revise the plans for changes my wife wants to make (small downscaling and some other changes). The current house is shown in the attached photo....

The blank wall below the balcony will be the connection to the unbuilt section. That balcony will become part of a second story terrace.
