* CHURCH OF THE BLUE CASTLE: It's been four years since the National Community Church purchased the Navy Yard Car Barn, aka the "Blue Castle," at 8th and M, and with all tenant leases now expired, an interior building permit application has been filed for creating a "worship space" for the church, along with support spaces "such as green rooms, production studio, and a kids room." Back in September, Capitol Hill Corner reported that these Phase I plans are for a 900-plus seat auditorium "which will be used for Sunday church services but will be available for rent to the community during days and nights." And, to answer the inevitable question, when I interviewed Mark Batterson about the purchase of the building, he said that he hopes "that someday the Blue Castle will just be the Castle."

* CHURCH OF THE A-1 TIRES: While developers have been trying to pitch a sliver of a residential building on the northeast corner of 1st and K since the lot changed hands in 2017, the only current movement at the site is an apparent plan to renovate the former A-1 Tires garage for a church assembly space, including a new roof and windows. Is perhaps the Waterfront Church looking to move from their Capitol Hill Tower space? We Shall See. UPDATE: I've been told that this is an expansion by the Waterfront Church, not a move.

* HARNESSING THE SUN MONSTER: If you've seen some construction activities on top of the Nats Park garages along N Street, it is the installation of "solar canopies" containing 4080 modules. (The only question remaining is, will the Sun Monster's number one victim be back this season to see these new additions?)

* WALLS COME TUMBLIN' DOWN?: After the Lerner Companies initially received approval to take the roof off of the old warehouse at 49 L but keep the lower 4 feet of brick walls, there is now a request to revise that permit to remove the wall completely "due to failing structural integrity," and to replace it with a new 8-foot chain link fence. There have been no development plans announced for this site, but one wonders if the Lerners might be thinking about some temporary parking options if indeed their 1000 South Capitol residential building is soon to get underway, which would necessitate the closure/move of Nats Parking Lot K.
