As can be seen it sits in a residential neighborhood in this rural community of SE MO. It had the typical signs on the door required by craft and vendors who would arrive there to work.
Bismark	Listing Updated: July 2010 Operating Company: at&t/SBC/Southwestern Bell CLLI: BSMRMOPERS0 Switch Type: Nokia/Alcatel/Lucent 5ESS Remote Prefixes Served: (573) 734 Notes: Bismark is a small farming community in eastern Missouri.

Bonne Terre is also part of the lead belt in Missouri and the town is dominated by a huge mountain of old tailings. The old lead mine here is flooded and is a scuba diving tourist attraction today.
Bowling Green	Listing Updated: July 2010 Operating Company: at&t/SBC/Southwestern Bell CLLI: BWLGMOEARS3 Switch Type: Ribbon/Genband/Nortel RSC Prefixes Served: (573) 324 Notes: Located in eastern Missouri. It houses a Nortel RSC hosted from Hannibal, MO. It is a classic 1950s style rural central office for Southwestern Bell Telephone. It sits right in the downtown business area and provides a nice covered entrance for bill payers to come in and do business.
Campbell	Listing Updated: July 2010 Operating Company: at&t/SBC/Southwestern Bell CLLI: CMPBMOCHRSH Switch Type: Ericsson AXE 10 Remote Prefixes Served: (573) 246 Notes: This Central Office is located in the Missouri bootheel. This is one of the many SE Missouri offices which are in the New Madrid earthquake zone where the quakes of 1811 & 1812 all exceeded Richter 8.0. It needed reinforcement to survive a quake but it was impossible to reinforce the building itself so an external Steel cage was built around the structure and then attached to the building.
Cape Girardeau	Listing Updated: July 2010 Operating Company: at&t/SBC/Southwestern Bell CLLI: CPGRMOEDDSA Switch Type: Nokia/Alcatel/Lucent 5ESS Host Prefixes Served: (573) 331-2, 334-5, 339, 519, 651, 730, 986 (618) 661 Notes: Also serves McClure, IL (618-661). It is home to a 5ESS switch which hosts the remotes of the “Cape Cluster”. I have shown it here when it carried the “SBC” signage because only a handful of offices ever got this logo deployed on them. This office is also a toll collection center for SE Missouri. The building once sported a radio tower but when the DR6-30-135 radio got turned off in the early 1990s, the tower went too.
Cape Girardeau (AT&T POP)	Listing Updated: July 2010 Operating Company: at&t (Long Lines) CLLI: None Switch Type: None Prefixes Served: None Notes: A Point of Presence for the AT&T Long Line (long distance) network. At the rear left of this building is one of the old radio repeater huts, the kind with pebbled concrete walls you see along the highways. It was more than doubled in size by the addition of the structure you see in this picture. The building houses regenerator equipment for the span from Hillsboro, MO. to Memphis, TN. Another place you need a guide to find.
Cardwell	Listing Updated: July 2010 Operating Company: at&t/SBC/Southwestern Bell CLLI: CDWLMOOLRSC Switch Type: Ericsson AXE Remote Prefixes Served: (573) 654 Notes: It houses an Ericsson AXE remote hosted by the Kennet, MO AXE. It serves a tiny bootheel farming town.
Caruthersville	Listing Updated: July 2010 Operating Company: at&t/SBC/Southwestern Bell CLLI: CTVLMOEDRSL Switch Type: Ericsson AXE Remote Prefixes Served: (573) 333 Notes: This CO is right downtown in a Mississippi river town, less than a quarter of a mile from the river, sitting in the alluvial soil of Southeast Missouri which will transmit an earthquake ground wave extremely well. (Better than it grows cotton?) The building could not be earthquake proofed so, like the New Madrid CO it got an earthquake proof cage built around it and the building was then attached to it. Those large steel panels across the front of the office protect passers by from flying glass if the big one hits and blows out all the glass in the front of the office. Caruthersville is one of the Missouri outstate casino towns too, it is home to a property owned by Isle of Capri casinos.
Chaffee	Listing Updated: July 2010 Operating Company: at&t/SBC/Southwestern Bell CLLI: CHFFMOTURSD Switch Type: Nokia/Alcatel/Lucent 5ESS Remote Prefixes Served: (573) 887 Notes: It serves a nice little Southeast Missouri farming town with a 5ESS remote which is part of the “Cape Cluster” hosted by the Cape Girardeau, MO 5ESS. It sits back a couple of streets from the main road through town and is a tough one to find at midnight for work in the maintenance window.
Charleston	Listing Updated: July 2010 Operating Company: at&t/SBC/Southwestern Bell CLLI: CHTNMOMURS2 Switch Type: Ribbon/Genband/Nortel RSC Prefixes Served: (573) 683 Notes: Yes, it is another river town in cotton country and it too needed the new Madrid earthquake treatment. This work was done in the late 1980s when Dr. Iben Browning was predicting a Richter 8 or worse quake for the new Madrid fault. No steel sheets required for this office because it does not have the huge plate glass windows found in Caruthersville and Hayti. The customers here are served by an RSC hosted by the Sikeston, MO DMS100.
Clarksville	Listing Updated: July 2010 Operating Company: at&t/SBC/Southwestern Bell CLLI: CLVLMOCIRS6 Switch Type: Ribbon/Genband/Nortel RSC Prefixes Served: (573) 242 Notes: This is a Mississippi river town at lock and dam 24. It houses a Nortel DSC hosted by the Hannibal DMS100. It is easy to drive right past this office because it is situated so far back from 2nd street that you think it is actually a First street address.
Columbia "Main"	Listing Updated: July 2010 Operating Company: Brightspeed/Centurylink CLLI: DS0: CLMAMOXADS0 DS1: CLMAMOXADS1 Switch Type: DS0: Automatic Electric GTD-5 DS1: Ribbon/Genband/Nortel DMS-100 Prefixes Served: DS0: (573) 256, 397, 441-3, 449, 499, 815, 817, 874-6 DS1: (573) 214, 474, 771, 814, 882, 884, 886 Notes: Columbia is the home of the University of Missouri main campus.
Columbia "East"	Listing Updated: February 2012 Operating Company: Brightspeed/Centurylink CLLI: (none) Switch Type: (remote switch from Columbia Main) Prefixes Served: (no unique prefixes) Notes: The small building in front houses a remote switch hosted from the downtown CO. The building addition behind it was added to accommodate Broadband access equipment about 15 years ago, that’s why the soffit and fascia don’t match on the addition.
Columbia (AT&T Long Lines) Photo 2	Listing Updated: October 2010 Operating Company: AT&T (Long Lines) CLLI: (unknown) Switch Type: (none) Prefixes Served: None Notes: It started life as one of the square brick repeater office shown on the right side of the building. Then a large addition was built behind that and both structures got the tin roof instead of shingles. It appears that the microwave tower is dead because there are no waveguides. It is not obvious but that third building behind the front structure is attached with a small connecting building. Notice the the pre-merger AT&T “deathstar” logo.
Cuba (AT&T Long Lines) Photo 2	Listing Updated: September 2012 Operating Company: AT&T Long Lines CLLI: ROLLMOAZ Switch Type: None (houses transmission equipment) Prefixes Served: (none) Notes: It sits right off the highway north of the town of Cuba, Missouri. In the 1960s it had a city limit sign which read, Cuba, MO "Cuba no Castro" underneath.
Deering	Listing Updated: July 2010 Operating Company: at&t/SBC/Southwestern Bell CLLI: DRNGMOPLRSM Switch Type: Ericsson AXE Remote Prefixes Served: (573) 757 Notes: This office is in a tiny bootheel farming town. It houses a remote swirtch hosted by the Kennett Erricson AXE. Since it sits in the middle of a field of alluvial soil it got the New Madrid earthquake reinforcement too, even though it sits 12 miles from the Mississippi river.
Dexter	Listing Updated: July 2010 Operating Company: at&t/SBC/Southwestern Bell CLLI: DXTRMOMARS0 Switch Type: Ribbon/Genband/Nortel RSC Prefixes Served: (573) 614, 624 Notes: It is a small town in SE Missouri which was famous for shoe manufacturing. It houses a remote hosted by the Sikeston DMS100. It sported the canvas sign proclaiming that SBC was building the Missouri information superhighway for a couple of years in the late 1990s.
Drake	Listing Updated: April 2011 Operating Company: Fidelity Communications CLLI: (none) Switch Type: (digital node) Prefixes Served: (573) 437 (from Owensville) Notes: This appears to be a digital node from nearby Owensville that serves the small town of Drake.
East Prairie	Listing Updated: July 2010 Operating Company: at&t/SBC/Southwestern Bell CLLI: EPRRMONIRS3 Switch Type: Ribbon/Genband/Nortel RSC Prefixes Served: (573) 649 Notes: This CO is located in southeast Missouri. It houses an RSC (Remote Switch) hosted by the Sikeston DMS100. This building did not require the severe earthquake reinforcement seen in New Madrid, all it got was the two steel “X” braces added to the front of the office.
Eldon	Listing Updated: July 2010 Operating Company: at&t/SBC/Southwestern Bell CLLI: ELDNMOEXDSA Switch Type: Nokia/Alcatel/Lucent 5ESS Host Prefixes Served: (573) 365, 392 Notes: Also serves parts of Lake Ozark-Osage Beach rate center (573-365). It houses a 5ESS switch which hosts a group of offices called the “Eldon cluster”. This is a great place to work because of its proximity to the “Lake of the Ozarks”.
Elsberry Photo 2	Listing Updated: September 2012 Operating Company: at&t/SBC/Southwestern Bell CLLI: ELSBMOTWRS5 Switch Type: Ribbon/Genband/Nortel RSC Prefixes Served: (573) 898 Notes: The EXchange here was TWinbrook. This is a 2 building facility with a 2 vehicle garage for company trucks. This is one of the Mississippi river towns between Hannibal and St. Louis in Missouri.
Farmington	Listing Updated: July 2010 Operating Company: at&t/SBC/Southwestern Bell CLLI: FRTNMOPLDS0 Switch Type: Nokia/Alcatel/Lucent 5ESS Prefixes Served: (573) 701, 747, 756, 760 Notes: It houses a 5ESS switch which hosts a number of remote sites. You can see vestiges of the old Southwestern Bell Telephone logo on the building. There has never been a town more honestly named than Farmington. It is a nice town in the heart of farming country.
Fisk	Listing Updated: July 2010 Operating Company: at&t/SBC/Southwestern Bell CLLI: FISKMOWORS4 Switch Type: Nokia/Alcatel/Lucent 5ESS Remote Prefixes Served: (573) 967 Notes: Houses a Lucent RSM hosted by the Poplar Bluff No. 5ESS.
Flat River (Park Hills)	Listing Updated: August 2010 Operating Company: at&t/SBC/Southwestern Bell CLLI: FLRVMOGEDSA Switch Type: Nokia/Alcatel/Lucent 5ESS Host Prefixes Served: (573) 327, 431, 518 Notes: It houses a 5ESS switch which hosts a few remotes. Park Hills was created in the 1990s as the result of a merger of four towns including Flat River. No one here calls it Park Hills, to us it is still Flat River. This is the biggest city in the lead belt.
Fredricktown	Listing Updated: July 2010 Operating Company: at&t/SBC/Southwestern Bell CLLI: FRTWMOSTRS2 Switch Type: Nokia/Alcatel/Lucent 5ESS Remote Prefixes Served: (573) 783 Notes: It houses an RSM hosted by Farmington, MO.

Fulton is also the home to Westminster College where Winston Churchill gave his famous “Iron Curtain” speech. At this college you can see an old English church and a section of the Berlin Wall as part of a monument to the visit of Mr. Churchill.
Gerald	Listing Updated: April 2011 Operating Company: Fidelity Communiations/Bourbeuse Telephone CLLI: GERLMOXARS3 Switch Type: Nokia/Alcatel/Lucent 5ESS Remote Prefixes Served: (573) 764 Notes: Bourbeuse Telephone only served the small ratecenter of Gerald.

Gideon Photo 2	Listing Updated: July 2010 Operating Company: at&t/SBC/Southwestern Bell CLLI: GIDNMOHIRSD Switch Type: Ericsson AXE Remote Prefixes Served: (573) 448 Notes: It houses an AXR hosted by the Kennett Erricson AXE switch. Gideon is another tiny farming community in the Missouri bootheel. In the one picture you can see the portable engine alternator which is used to power this building in case of a major power outage exceeding 8 hours. This generator and hundreds of others have been to Galveston and other points south to serve during recovery efforts after hurricanes and ice storms.
Hannibal Photo 2	Listing Updated: July 2010 Operating Company: at&t/SBC/Southwestern Bell CLLI: HNBLMOACDSA Switch Type: Ribbon/Genband/Nortel DMS-100 Prefixes Served: (573) 221, 231, 248, 406, 629 Notes: This office houses a Nortel DMS100 which hosts a number of remote switches. Hannibal is, obviously, the home town of Mark Twain & Molly Brown. It is a great tourist destination for anyone who has read “Huckelberry Finn” or “Tom Sawyer”. It has a great classic SWBT logo over the door carved into the stonework.
Hayti Photo 2	Listing Updated: July 2010 Operating Company: at&t/SBC/Southwestern Bell CLLI: HAYTMOFLRSJ Switch Type: Ericsson AXE Remote Prefixes Served: (573) 359 Notes: This town was founded by ex-slaves who knew about Haiti and its slave revolt. They did not know how to spell the island so they named their town phonetically! You can see that they used the standard SEMO earthquake protection developed for New Madrid on this office.
Hornersville	Listing Updated: July 2010 Operating Company: at&t/SBC/Southwestern Bell CLLI: HRNVMOPERSA Switch Type: Ericsson AXE Remote Prefixes Served: (573) 737 Notes: This is an earthquake reinforced Missouri bootheel central office. It houses a remote switch hosted by the AXE in Kennett.

Jackson	Listing Updated: July 2010 Operating Company: at&t/SBC/Southwestern Bell CLLI: JCSNMOCIDS0 Switch Type: Nokia/Alcatel/Lucent 5ESS Prefixes Served: (573) 204, 243 Notes: Jackson is a nice little town near to Cape. There is an old branch line railroad there that gives short tourist rides to visitors, with a steam engine if you are lucky.
Jefferson City Photo 2	Listing Updated: April 2012 Operating Company: Brightspeed/Centurylink/Embarq/Sprint/United Telephone CLLI: JFCYMOXADS0 JFCYMOXA1XD Switch Type: DS0: JFCYMOXADS0 1XD: JFCYMOXA1XD Prefixes Served: DS0: (573) 556, 632, 634-6, 638, 659, 681, 761, 893 1XD: (573) 522, 526, 751 Notes:
Kennett	Listing Updated: July 2010 Operating Company: at&t/SBC/Southwestern Bell CLLI: KNNTMOTUDS1 Switch Type: Ericsson AXE10 Prefixes Served: (573) 717, 888 Notes: It houses the largest Erricson AXE in Missouri. It is easily the largest central office in the bootheel. It now displays the new AT&T logo at the center top of the building. The building is a bit difficult to find because this town has a sprawling business district.
Kingdom City (AT&T Long Lines) Photo 2	Listing Updated: July 2010 Operating Company: AT&T Long Lines CLLI: KDCYMORS Switch Type: None Prefixes Served: None Notes: The tiny little hut is the working building today. The large building was an AT&T Long Lines radio repeater site. AT&T has given this building to the municipal government who has to pay the electric bills for keeping the tower lights on for aviation safety. The tower still has antennae on it but they are now for cellular, no horns or microwave dishes. Kingdom City is in Callaway county.
Lake Ozark-Osage Beach "Horseshoe Bend"	Listing Updated: July 2010 Operating Company: at&t/SBC/Southwestern Bell CLLI: (was HSBNMOHBRS1) Switch Type: Nokia/Alcatel/Lucent 5ESS Remote Prefixes Served: (573) 964 Notes: This building houses a Remote switch hosted by the Eldon 5ESS. This new building is less than 10 years old. There is no town named Horseshoe Bend, it describes the shape of that part of the lake. People who don’t know the lake never can find this office.
Lake Ozark-Osage Beach "Lake Ozark" Photo 2 | Photo 3	Listing Updated: June 2011 Operating Company: at&t/SBC/Southwestern Bell CLLI: LKOZMOENRS0 Switch Type: Nokia/Alcatel/Lucent 5ESS Remote Prefixes Served: (573) 964 Notes: It houses a 5ESS remote Switch hosted by the Eldon, MO 5ESS switch. This office is located by Bagnell dam which was built to form the Lake of the Ozarks. It generates a huge amount of electricity for Ameren UE, a Midwestern power utility. As you can see in these pictures the office has a large parking lot with storage facilities for a portable engine alternator and at least 1 company truck.
Lake Ozark-Osage Beach "Osage Beach"	Listing Updated: July 2010 Operating Company: at&t/SBC/Southwestern Bell CLLI: OSBHMOFIRS4 Switch Type: Nokia/Alcatel/Lucent 5ESS Remote Prefixes Served: (573) 302, 348 Notes: It houses a remote switch hosted by the Eldon 5ESS. When you are around the Lake of the Ozarks you are in party town and Osage Beach is not party central but it is close. The office sits right on business 54, the busiest little road in central Missouri.
Leadwood	Listing Updated: July 2010 Operating Company: at&t/SBC/Southwestern Bell CLLI: LDWDMOLORS3 Switch Type: Nokia/Alcatel/Lucent 5ESS Remote Prefixes Served: (573) 562 Notes: It houses a remote switch hosted by the Park Hills (Flat River) 5ESS switch. This is lead country in Missouri and there are reminders of it everywhere for 50 miles on either side of this town.
Linn	Listing Updated: July 2010 Operating Company: at&t/SBC/Southwestern Bell CLLI: LINNMOTWDS1 Switch Type: Ericsson AXE10 Prefixes Served: (573) 897 Notes: This is home to another of the Ericsson AXE10 host switches, this one serves the Westphalia “LATA” formed at the whim of Judge Harold Green in the 1983 divestiture ruling. The Comm Tech who turned up this office and all of its remotes is Dan Ramsay (retired), now an instructor at the fine academic institution, Linn State Technical College.
Louisiana	Listing Updated: July 2010 Operating Company: at&t/SBC/Southwestern Bell CLLI: LOSNMOSKRS4 Switch Type: Ribbon/Genband/Nortel RSC Prefixes Served: (573) 754 Notes: If you love Mississippi river towns, you will love Lousiana almost more than any other. It is very picturesque, it gives you an easy view of the mighty river from a distance. The people are gracious to strangers. You may literally, step out the door of the office and see the river. It houses a remote switch hosted by the Hannibal DMS-100.
Marble Hill	Listing Updated: July 2010 Operating Company: at&t/SBC/Southwestern Bell CLLI: MRHLMOBERSH Switch Type: Nokia/Alcatel/Lucent 5ESS Remote Prefixes Served: (573) 238 Notes: It houses a remote switch module hosted by the Cape Girardeau 5ESS. Do not attempt to find this office for the first time at midnight. It is in a small town which has a sprawling business district and the office could be anywhere. If you follow fiber path signs to get there you may easily end up going from Cape to Jackson, the long way.
Marston	Listing Updated: July 2010 Operating Company: at&t/SBC/Southwestern Bell CLLI: MRTNMONIRS2 Switch Type: Ribbon/Genband/Nortel RSC Prefixes Served: (573) 643 Notes: The building houses a remote switch hosted by the DMS100 in Sikeston, MO. This is one of the river towns in the bootheel but the building is sufficiently robust that it did not require external bracing. I am not sure why AT&T felt it necessary to build a chain link fence around this building and top it with barbed wire but they did.
Meta	Listing Updated: July 2010 Operating Company: at&t/SBC/Southwestern Bell CLLI: METAMOBARS3 Switch Type: Ericsson AXE Remote Prefixes Served: (573) 229 Notes: This CO is in a tiny town in Central Missouri.

Mexico	Listing Updated: July 2010 Operating Company: at&t/SBC/Southwestern Bell CLLI: MEXCMOJUDSA Switch Type: Ericsson AXE10 Prefixes Served: (573) 473, 581-2 Notes: It houses a host Ericsson AXE10 switch for a central Missouri cluster. You used to find a public telephone outside almost every Central Office, by 2005 this was one of the few working phones left. It is no longer there, cell phones finally made it irrelevant.
Montgomery City	Listing Updated: July 2010 Operating Company: at&t/SBC/Southwestern Bell CLLI: MTCYMOLORS1 Switch Type: Ericsson AXE Remote Prefixes Served: (573) 564 Notes: It houses a remote switch hosted by the Mexico AXE10. It serves a farming community in middle Missouri and the switch sits in between the business district and the residential part of town.
Morehouse	Listing Updated: July 2010 Operating Company: at&t/SBC/Southwestern Bell CLLI: MRHSMONORS6 Switch Type: Ribbon/Genband/Nortel RSC Prefixes Served: (573) 667 Notes: It houses a remote switch hosted by the Sikeston, MO DMS100. The “New Madrid” style of external earthquake bracing was used for this CO in the 1980s.
New Madrid	Listing Updated: July 2010 Operating Company: at&t/SBC/Southwestern Bell CLLI: NWMDMOSHRS0 Switch Type: Ribbon/Genband/Nortel RSC Prefixes Served: (573) 748 Notes: This is the town the New Madrid fault is named after. The office houses a remote switch hosted by the Sikeston DMS100. In this office the intent was to reinforce the foundation to protect against a future earthquake. It was discovered that the original foundation concrete had deteriorated over time and normal reinforcement was impossible. The Southwestern Bell engineering staff came up with this clever alternative, They built a robust frame around the building and attached the building walls and roof to it!
Old Appleton	Listing Updated: July 2010 Operating Company: at&t/SBC/Southwestern Bell CLLI: OLAPMOSTRSQ Switch Type: Nokia/Alcatel/Lucent 5ESS Remote Prefixes Served: (573) 788 Notes: It houses a remote switch hosted by the Cape Girardeau 5ESS switch. It sits in the center of this little southeast Missouri farming community.
Oran	Listing Updated: June 2011 Operating Company: at&t/SBC/Southwestern Bell CLLI: ORANMOCORSJ Switch Type: Nokia/Alcatel/Lucent 5ESS Remote Prefixes Served: (573) 262, 583 Notes: It is a rural office in Southeast Missouri which houses a 5ESS remote switch hosted by the Cape Girardeau switch. Oran is a pleasant little farm town and so it is not surprising to see that the office was a small house downtown which has since been augmented by 2 building additions. The one next to the house was built first, the one in the rear was built for a small ESS switch back in the late 1970s.
Patton Photo 2	Listing Updated: August 2010 Operating Company: at&t/SBC/Southwestern Bell CLLI: PATNMOTORSG Switch Type: Nokia/Alcatel/Lucent 5ESS Remote Prefixes Served: (573) 866 Notes: This office serves a southeastern Missouri farm community. It houses an RSM hosted by the Cape Girardeau 5ESS. The signage shown here was replaced in 2009 with new AT&T appropriate material.
Paynesville	Listing Updated: August 2010 Operating Company: at&t/SBC/Southwestern Bell CLLI: PYVLMOTIRS7 Switch Type: DRL Prefixes Served: (573) 847 Notes: This is a northeastern Missouri Central Office. The RLCM (Remote Line Concentrator Module) in this office is hosted by the Hannibal DMS100. The portable generators like the one shown in this picture are losing favor in AT&T as they seem to disappear in southern states in the aftermath of hurricanes.
Perryville	Listing Updated: August 2010 Operating Company: at&t/SBC/Southwestern Bell CLLI: PRVLMOLIRSL Switch Type: Nokia/Alcatel/Lucent 5ESS Remote Prefixes Served: (573) 517, 547 Notes: It houses a Remote Switch Module hosted by the Cape Girardeau 5ESS. There may be nicer farm communities than this one in the US but they would be difficult to find.
Pocahontas	Listing Updated: August 2010 Operating Company: at&t/SBC/Southwestern Bell CLLI: PCHNMOTERSM Switch Type: Nokia/Alcatel/Lucent 5ESS Remote Prefixes Served: (573) 833 Notes: It houses a Remote Switch Module hosted by the Cape Girardeau 5ESS.

Poplar Bluff Photo 2	Listing Updated: August 2010 Operating Company: at&t/SBC/Southwestern Bell CLLI: PPBLMOSUDSA Switch Type: Nokia/Alcatel/Lucent 5ESS Prefixes Served: (573) 686, 727, 776, 778, 785 Notes: It houses a 5ESS switch. You don’t often find a Central Office that has grown so large it fronts on two streets in a town of less than 20,000. This farming community is close to Lake Wappapello and is the county seat for Butler county. The people here are very friendly, cost of living is low and fishing, lake and river, is handy. Photo shows the older part of the building. You just can’t see it all unless you look both at the Vine street entrance (2 story) and the Pine Boulevard entrance (3 story). It’s kind of interesting how Southwestern Bell, in the 1960s stopped even trying to match original brick and architectural styles in these rural offices.
