On a few maps, this false-shutter-and-keystone-bedecked Arlington Court home appears to occupy a lot at the corner of E. Terrace Dr. and E. Terrace Dr. One of those streets, however, is just a stub serving 4 driveways within the enclave development just east of Memorial Park. The property is one lot in from the Memorial Dr. entry of the ungated-but-guarded neighborhood. That puts it on the block-long main drag — the only straight shot in the community of mostly front-loading, 2-story homes lining winding roads, a cul-de-sac, and one loopdeloop. (One interior street discreetly ties into Crestwood Dr. and its by-the-bayou estates.) Listed last week at $1,295,000, this property with a side-loading double driveway previously changed hands in April 2009 for $1 million and change.
