The planned River House condos appear to be only 6 stories. That means they likely will be stick-built construction: The floors and ceilings will not be concrete as they are in the Eclipse. That will certainly impact fire-safety and noise-transmission negatively. Don't be fooled: Those newer brick-faced homes south of us on Potomac Avenue are not concrete/masonry. If you noticed while they were under construction, they are stick-built!
(2019: With the HQ2 developments, it is unlikely the River House condos will ever be built.)
