- Description
- Maurice Stephens is a 19th century (1816) masonry farmhouse with attached kitchen ell. The main, five-bay wide, original structure was finished with exposed field stone and ridge pointing. The kitchen ell, on the east elevation of the main structure, was constructed in ca. 1840-41. The ell is field stone with rough cast mortar and whitewashed. The structure is located on the 1777-78 Winter Encampment Grand Parade and has a strong visible presence in the cultural landscape. Although unrelated to the 1777-78 Winter Encampment, the structure represents the character of the masonry farmhouses prevalent in southeastern Pennsylvania and in the cultural landscape of Valley Forge during the late 18th and early 19th century. Maurice Stephen's House is a contributing structure to Valley Forge NHP's National Register Nomination. A one story, three sided bay was added to the south faade of the structure sometime prior to 1902. A portion of the exterior, masonry wall was removed at that time to incorporate the newly created interior bay space with the corresponding room. The basement window directly beneath the bay was in-filled. The bay was later removed and the masonry wall rebuilt and the interior wall re-plastered. Unfortunately, care was not taken to support the second floor masonry wall when the bay was removed and the second floor exterior wall settled. This, in turn, caused the two second floor window frames to rack and the roof rafter plate to deflect. In order to re-roof the structure effectively it was necessary to install a series of temporary screw jacks, on all floors, that effectively lifted the rafter plate and rafters into alignment with the rest of the roof. In order to correct the window problem and the settled wall, that section of the exterior wall needs to be rebuilt from the top of the basement wall up through the second floor so that the wall once again structurally supports the rafters allowing the current screw jack supports to be removed. All windows are late 19th or early 20th century replacements and do not relate to the period of original construction. Furthermore, they are not energy efficient due to deterioration of sashes that are no longer tightly fit within their frames. The original exterior, masonry pointing has been replaced with several different campaigns of inappropriate Portland cement based, ribbon pointing in non-contiguous locations. The original exterior doors are not weatherized and contribute to loss of heat and air infiltration. The elevations, particularly on the north and south faade of the main, five-bay block, have been raised from their original level. Ideally, they should be lowered to permit the new pointing to be extended to near the original ground elevation and to permit the window wells to be rebuilt and three of the four windows replaced. Lower grade to the height of the existing retaining wall on the entire south side. (Note: existing retaining wall will NOT be demolished and a new one as noted on drawings will NOT be built.) Remove stone foundation of the demolished three sided bay. Carefully remove the settled section of the masonry wall, from the foundation through to the rafter plate. At the same time, stabilize the adjacent masonry wall of the house from collapsing. Re-open basement window opening marked "2" on sheet A-37. Carefully remove frame and horizontal bars at window opening "1". Install two new basement window frames in openings "1" & "2". Build the two new window wells on the south faade. Rebuild frame and supply sufficient lintel to support rebuilt masonry wall above window opening "2". Remove and retain the racked window frames and sash from the wall section demolished. Rebuild the wall to structurally support the rafter plate and the rafters so that they are in plane with the rest of the roof structure. Re-square the openings for the two first and two second floor windows. Restore the window frames and re-hang the sash only if Option 1 does not become a part of the contract. Re-plaster the interior walls on the first and second floor where the masonry wall was rebuilt and feather it into the adjacent interior plaster walls. Re-point the entire south exterior faade in the manner specified. Supply new stone steps and stoop at south faade door.
