J. Twaits Company consisting of limited partners of
Ford J. Twaits, Edna M. Twaits and Jane E. Twaits with

Morrison & Knudsen Company are both listed in Dunn and

308 "A" houses and 330 "B" houses were built by Smith,
Hoffman & Wright Co. It is believed that this company
was formed only for the construction of houses and
buildings on the Hanford Project. It is believed that
Mr. F. M. Cocrene, Project Manager for the Hoffman
Construction Co. that has several contracts on the
Project at the present time, was a masonary and
concrete superintendent under the Smith, Hoffman &
Wright Contract in 1944. The Smith, Hoffman & Wright
contract dated August 4, 1943 was for an estimated
contract price of $7,559,995.20 and consisted of the
building of houses, warehouse building, dormitories,
theatre building, fire pump house and dewage treatment
plant. Additional work was added to this contract until
the total contract price amounted to $17,096,861.36.
Narrative from the General Building Plans [November, 1943]

The "B" house [is a duplex]... Each family unit is
identical, the house, like the "A" house, being
symmetrical about a central axis. Thus again each house
is similar in every respect except that the left hand
unit is always the reverse in plan of the right hand

The advantages of light and ventilation discussed in
connection with the "A" house are true of this unit
also. The two bedrooms are kept on the exterior angles
of the house so that each will have two exposures and
diagonal ventilation. The living room is kept to the
party wall but as the dining room is of the alcove
type, fully open on one wall to the living room, there
is adequate cross ventilation from side to side of
these two rooms. The bathroom and kitchen are grouped
together in the rear center of each unit with the
stairway to the basement intervening. Thus there is a
grade entrance or outside door at grade level in each

This well tested, standard arrangement permits direct
access from the basement to the outdoors, from the
outdoors to the first floor via the kitchen via the
grade landing. With this plan, service trips from
outdoors to the basement do not interfere with or
'dirty up" porch or railings. The stair landing serves
in a measure as a rear hall or intermediate space
between yard and kitchen, another factor in keeping the
kitchen tidy. The wall and door on the kitchen level,
which are familiar to this scheme, are omitted; for
safety, however, a door or gate has been introduced
between the landing and the basement. This plan, it was
felt, would avoid the awkwardness of an extra door in
the already small kitchen.

If the service rooms are compact in this layout, the
closet and storage space can only be considered
generous under any standards. Besides the basement
area, there are, on the first floor, five ample closets
using every available inch of what would otherwise be
lost space. There are two closets in the living room,
both large. One is bulk headed over the basement
stairs, the other is adjacent to the front door. Each
bedroom has ample wardrobe type closets. In the bedroom
hall there is a linen closet and a closet suitable for
storing cleaning equipment. Privacy in the bedroom
hall, with circulation from each bedroom to the bath,
is achieved at a minimum cost of floor area and without
unnecessary doors.

The living room, while smaller than its counterpart in
the "A" house, is ample and of good proportions. When
in the house, one feels a sense of space and openness,
except in the kitchen. By ordinary standards this room
is definitely minimum for this size of house. The
refrigerator, however, will supplement the storage
facilities, which consist of about 10' 9" of upper
cupboards of two and three shelves and about 7' 3" of
lower cabinets including those under the sink. There
are four drawers, and two bins on rollers in this
space. The flush rim sinks and set in linoleum covered
tops with linoleum backs are standard throughout the
project. The stove sets free against the dining room

The trim and finish are uniform with all units. Casein
painted dry wall construction has a painted soft wood
trim. The floors are natural fir. Outside, the houses
are finished mainly in soft colored pre dipped heavy
cedar shakes with some variants in design using
vertical siding either in the gables or as sort of
exterior wainscot, because of the decidedly horizontal
lines, this unit seems to hug the ground better than
the two story unit and is decidedly pleasing in
