See this 1/12/2011 message from LeDroit Park resident and North Capitol Street NW firehouse owner Brian Brown:
firehouse project now underway
Feel free to let the neighbors know that we have all the necessary finances in place to proceed with the [firehouse] project.
We have obtained the necessary permits to demo the areas necessary and that is being done.
The windows are also being prepped for replacement.
Historic signed off on the architectural design of the replacement garage doors yesterday and those are being ordered.
Look for the ABRA application to come up in one of the next couple of ANC meetings.

That’s exciting news. Is it going to be as it was originally planned? Resturant/art space?
