Since the show website
www.qualitystreetshowcase.com just has directions to the Newport High School shuttle, I'll give direction to the site. One of the actual house address' is 15546 SE 79th Place, Newcastle. However, do not mapquest.com this as their roads are not current enough to pick up on these new streets. For those of you that know the main entrance to the Newcastle golf couse, you turn off of SE Newcastle Coal-Creek Road onto 155th Ave SE (that's were the entry monument signs are), and instead of taking a right on Six Penny Lane to go up to the clubhouse, just go straight and take the first left on SE 79th Place (Prestwick Neighborhood). The security guard or attendant will then waive you on in.
