1940's Picture front

Picture from a 1940's news paper of the front of the Patrick St. Lawrence house. Note that the porch extends almost the entire length of the house. 1/2 dovetailed mortises without wooden pegs were found in the sill beam. The original 1790 mortise was rectangular and the tenon was secured using wooden pegs.

Picture 1955

The front porch was recreated from a Anne Bynum's painting. The Yellow house was also painted a federal blue color in this painting. Janet hand scraped some beaded siding boards on the back porch and found this layer blue.

Anne Bynum Painting

The Patrick St. Lawrence Tavern House, was located on the corner lot number 50 of the courthouse square,  is blue house located in the front left corner of the oil painting. Janet found layers of white, blue and different shades of yellow. The original color was a mustard to gold in color.

The front porch as was first seen prior to purchase. This porch was not well built or flashed. There was major water damage-decay to the post and beam structure in this area. Note the columns that are used were the same as on the 1940's picture.

Hours of research has been completed  to determine the correct style of porch columns that would have been used in the late 18th century on a Georgian style house. The consensus was that lamb-tongue columns would be the correct choice, many buildings of this era in the Piedmont area use the lamb-tongue style columns.

 requested to visit the St. Lawrence house to inspect and document an early American structure. With the plaster and lath removed many years ago, the bones of this house are now exposed. I believe that they were extremely impressed with the large timbers, framing methods and massive door and window casings, falling wainscot panels and the dividing wall that hinges to the ceiling creating a ball room.

I ask them a question about the exterior balustrade and they stated "to keep it simple", with the balustrade being exposed to the elements, there would not have been a great investments in the railing system.

Oak Grove Plantation Column A second photograph of the Oak Grove Plantation porch shows a simple railing system with an oval toped hand rail. My plan for the Patrick St. Lawrence house was a duplication of the interior balustrade  for the front porches. The exterior and interior finish details showed a minimum of molding designs. The country carpenter in the 18th century may not have had a large selection of molding planes to choose from, and the St. Lawrence house moldings-trim was created using hollow, rounds, bead and fillister planes.

Lambs Tongue columns on Garrett-White House built c.1785 with a restoration front porch. The Garrett-White porch is very close to the porch that will be built at the Patrick St. Lawrence house.

Old porch has been removed and the foundation readied for new porch

Old porch was removed and the pressure treated sill plate is reattached to the foundation for the start of the new porch.

I know that pressure treated lumber was not used in the 18th century, but sometimes it is good to bent the rules! The porch new porch should last longer with this barrier between wood and masonry.

Lambs-Toungue columns The start of a recreation 18th century porch. The Patrick St. Lawrence house was built for use as a tavern and all architectural components were masses in size. The columns were designed and crafted with the same thought in mind.

Back porch

The back porch in this picture was modified from a porch that ran the length of the back of the house. The porch most likely looked like the one pictured in the 1940's news paper picture. The small room to the left was framed into the porch to create a full bath. We have removed the bath, installed a new floor and will be installing a small galley kitchen that will work in tandem with a large country kitchen.
