McDonald Bluff CBU & Mail Kiosk Cover

Mitchell Metals supplied and installed a 14-box back-to-back CBU mail kiosk cover at McDonald Bluff in Bethlehem, Georgia, for home builder Bassett Signature Homes. The structure uses 6×6 aluminum posts and beams finished in Dark Bronze, and was delivered as a turnkey package that included the cluster box units.
The whole install, from the air
McDonald Bluff is a new single-family community in Bethlehem, Georgia, in Barrow County about an hour east of Atlanta. Bassett Signature Homes was flying the site for their own progress documentation and captured our crew building the mail center from the ground up — posts, beams, decking, and cluster box units — as a time-lapse.
We don’t often get to see our own work from that angle. Most of what we photograph is the finished structure, which tells you what a mail center looks like but not how quickly one goes in. The drone footage answers that second question, and the answer matters to any developer scheduling the tail end of a project.
Why the schedule is the real story here
Mail centers have a habit of becoming the last open item on a residential development. The pad gets poured, and then the cluster boxes come from one vendor, the cover from another, and the two schedules don’t line up — so the amenity that every resident uses on day one is the thing holding up the closeout.
Mitchell Metals delivers the boxes and the cover together as one turnkey package: one submittal, one crew, one schedule. At McDonald Bluff that meant the structure went from bare concrete to a finished, code-compliant mail center in a single mobilization — which is exactly what the time-lapse shows.
Dark Bronze, 6×6 posts, and a back-to-back layout
The structure was finished in Dark Bronze with 6×6 posts and beams. The heavier post and beam profile carries the load with margin and visually anchors the canopy so it reads as permanent architecture rather than a lightweight shelter. Dark Bronze is the finish most residential developments choose because it recedes against landscaping and coordinates with the dark exterior hardware common on new homes.
The 14-box back-to-back configuration puts two banks of cluster boxes under one roof structure on a single pad. It keeps the footprint tight, keeps site work economical, and lets residents collect mail from either side without crowding.
Every Mitchell Metals canopy system is extruded aluminum, so nothing on the structure rusts. Our systems are engineered to ASCE 7-16 wind and snow loads and designed to meet ADA and IBC requirements, with layouts that follow the USPS Builders/Developers Guide for cluster box placement and approach.
Who we worked with
A Georgia home builder with more than two decades of work across the region, founded by Tim Bassett. Bassett Signature Homes is the builder behind McDonald Bluff in Bethlehem, and captured the drone footage of this installation.
Headquartered in Marietta, Georgia, Mitchell Metals engineers and fabricates pre-engineered aluminum canopy systems in-house and delivers CBU mail centers as a complete turnkey package.
Mitchell Metals values partnerships as much as the products we provide. Our thanks to the Bassett Signature Homes team for the relationship — and for the view from above.
One mobilization, start to finish

1
Posts and beams
The 6x6 posts are set and braced on the finished pad and the perimeter beams are flown into place. Cluster box units and decking stage on the trailer alongside.

2
Decking
Roll-formed flat-pan decking goes on across the frame. The cluster box units stay boxed until the roof is closed in, so nothing sits exposed on site.

3
Boxes set
Cluster box units are mounted to the pad in their back-to-back banks under the finished canopy. The crew demobilizes and the mail center is ready for USPS.

Why these specs were chosen
Back-to-back configuration. Two banks of cluster boxes share one roof structure and one pad — the most efficient layout when a community’s mail volume exceeds what a single row of boxes can serve.
Dark Bronze finish. A factory-applied finish on extruded aluminum. It holds color, hides road dust and pollen better than lighter finishes, and coordinates with the dark exterior hardware common on new residential construction.
6×6 posts and beams. A heavier structural profile than the minimum required, chosen for durability and for the visual weight it gives the structure.
Turnkey delivery. One vendor for the boxes and the cover means one submittal, one schedule, and no gap between two trades at the end of a project — which is usually when mail centers get built.
