David Condon, AIA; interview December 11, 1969. The earlier room
layout of the central block of the house had two rooms, each
about 12 by 12 feet, on each side of the central hallway which
ran through the house widthwise. Each of these four rooms had
its own fireplace located in the end wall. This pattern was
duplicated in the four rooms on the second floor.

A somewhat unusual feature of this building was that the
joists for the first and second floors ran lengthwise rather
than across the house. They were anchored in the brick outer
wall and in a brick bearing wall running the width of the
house in the basement and extending up to the second floor. In
1960, it was found that this wall was crumbling and in danger
of allowing the second-floor joists to pull out of their
sockets. The installation of a series of steel columns holding
up a steel beam had the effect of taking all bearing weight
off this original segment of brick wall.

[89] _Ibid._ The location of this masonry wall in the basement and
its extension upward to the second floor made it possible for
the original house to have the floor joists set lengthwise
with the house instead of front-to-back. The joists were thus
anchored in the outside walls at each end of the house and in
the center wall running midway through the house.

[90] Walter Macomber, interview held July 16, 1968, at Green Spring
Farm. Mr. Macomber's description of these shingles is as
follows: "This shingle is something I helped develop for
Williamsburg. We never did use it extensively, but it was made
... in Richmond [by] a man named Hendricks.... It's made of
concrete reinforced with two or three wires to the length of
it."

[91] _Ibid._ This stairway was also reversed when it was moved into
the library. As it originally stood in the hallway, the
stairway ran upward from front to rear of the house, and a
stairway to the basement was constructed underneath so as to
run down to the basement from the rear to the front of the
house.

A second stairway between the first and second floors was also
installed in a new staircase constructed in the new kitchen
(west) wing built in 1942.
