UPPER LEVEL INVENTOR. ROBERT E cRulvl'r FIQ 5 ATTORNEY United States Patent O 3,552,075 DWELLING UNIT OF THE FIXED FLOOR-PLAN TYPE Robert F. Crump, 1503 Thackeray Drive, Louisville, Ky. 40205 Filed May 28, 1969, Ser. No. 828,525 Int. Cl. E04h 1/00, 1/04 US. Cl. 52236 15 Claims ABSTRACT OF THE DISCLOSURE A dwelling unit of substantially fixed floor plan has front, rear and opposite side boundary walls enclosing a dwelling space embracing a peripheral area surrounding a rectangular center area. Fixed peripheral wall means in the peripheral area cooperate with said boundary walls to provide: along each front wall, a pair of front corner rooms separated by an access hall; along each rear wall, a pair of rear corner rooms separated by a pair of back rooms; and, along each side wall, an outer bathroom and an inner transversely-extending bathroom corridor, the bathroom separating and the corridor interconnecting adjacent front and rear corner rooms. Fixed center wall means in the center area provide a closet wall, extending longitudinally from one bathroom corridor to the other, and cooperate with said peripheral wall means to provide a pair of similarly-extending hall and center corridors, respectively extending along the front and back sides of the closet wall, the front-hall corridor passing through a pair of access doorways, one for each front corner room.

The foregoing dwelling unit provides one large apartment having a fixed floor plan, which embraces 6 rooms, 2 baths and an access hall. By installing a removable closure across the middle of the center corridor, said unit provides a pair of 3 room, 1 bath apartments, each accessible from the access hall. By locating that removable closure across either end of the center corridor, one apartment is reduced to 2 rooms, the other increased to 4 rooms.

BACKGROUND OF THE INVENTION Field of the invention This invention relates to improvements in fixed floorplan dwelling units.

Description of the prior art In planning low cost apartment buildings, it is often desirable to provide for one, two, three and sometimes 4 bedroom apartment units and more or less necessary to use fixed floor plans which, to a large extent, restrict each apartment to a fixed number of rooms. This has forced the designer to guess as to how many apartments he should provide in each different fixed-room category. As a consequence, when the apartment is built, the owner may be faced with the problem of modifying the fixed floor plans of one or more apartments to meet a current demand for apartments having a smaller or larger number of rooms.

It has been proposed heretofore, to solve this problem (or a related one) through the use of one or more shiftable partitions. Thus the Davison Pat. No. 2,372,768 confines the fixed load-bearing walls of the house to the external boundary walls thereof and sub-divides the enclosed space through mobile wall panel units as desired. The Robertson Pat. No. 2,752,675 uses castered closetproviding mobile wall units for storage-space providing and room sub-dividing purposes. The Dadrus Pat. No. 3,055,061 employs mobile interior walls which can be arranged and rearranged with the same ease as furniture. The Van der Lely Pat. No. 3,292,327 provides modular box car units which can be arranged side-by-side to provide habitation space on a single floor and superimposed to provide plural floors. None of these solutions are entirely satisfactory.

SUMMARY OF THE INVENTION Objects of the invention The principal objects of the present invention are: to avoid the necessity of planning in advance to provide a proposed apartment 'building with a fixed number of apartment units in each of several different fixed-room categories; to avoid the necessity of fixing the number of apartment units it should have in each different fixedroom category; and to provide for a multiplicity of fixed floor plan apartment units which can be easily, quickly and simply made to function, at one time, as one large apartment and, at another time, as two smaller apartments of equal or unequal size and thereby accommodate the current demand for smaller or larger apartments without significant modification either of any apartment or of any basic floor plan.

Other important objects of the present invention are to provide: an apartment unit having a fixed basic floor plan, which, while containing fixed walls delimiting fixed rooms interconnected by fixed corridors, provides a flexible arrangement that can be easily, quickly and simply made at one time to function as one large apartment and, another time, to form two smaller apartments of equal or unequal size; and to accomplish the foregoing objects without necessarily modifying any of the fixed structural elements of the building.

Another important object is to include, in said fixed basic floor plan, the provision of utility connections permitting the optional location of a kitchen within either a front or back room without requiring any appreciable modification of any fixed structure of the basic design.

Statement of the invention All of the objects of my invention are achieved in a fixed floor-plan dwelling unit which is constructed in accordance with the preferred embodiment of my invention, this preferred unit comprising: (A) front, rear and opposite side boundary walls enclosing an apartment space having a rectangular center area and a surrounding peripheral area; (B) fixed peripheral wall means in the peripheral area cooperating with said boundary walls to provide, (1) along each front wall, a pair of front corner rooms separated by an acess hall, (2) along each rear wall, a pair of rear corner rooms separated by a pair of back rooms, and (3) along each side wall, an outer bathroom and an inner transversely-extending bathroom corridor, the outer bathroom separating and the inner corridor transversely interconnecting adjacent front and rear corner rooms; (C) fixed center wall means in the center area providing a closet wall extending longitudinally from one bathroom corridor to the other and cooperating with said peripheral wall means to provide a pair of similarly extending hall and center corridors respectively along the front and back sides of said closet wall, said front-hall corridor passing through a pair of access doorways, one for each front corner room; and (D) means framing, across said back-side center corridor, an opening which, when said apartment space is to be used as a double bathroom apartment, interconnects the space on its opposite sides, and which, when said apartment space is to be divided into a pair of single bathroom apartments, is arranged to receive a removable apartment separating closure.

FIG. 5 is a fragmentary view showing how the design of FIG. 4 may be varied; and

FIG. 6 is a plan view of an apartment unit embodying a single dwelling form of my invention.

BRIEF DESCRIPTION OF FIGS. 1AC AND 2 Boundary walls The floor plan of the entry level unit shown in FIG. 1B comprises: fixed front, rear and opposite- side boundary walls 1, 2, 3 and 3' enclosing an apartment space having a rectangular center area and a surrounding peripheral area. This apartment space is divided into somewhat identical halves on opposite sides of the transversely extending vertical plane indicated by line 44.

Wall means in peripheral area Fixed walls 6, 7, 8, 9 and 10, in the left half of the peripheral area and 6', 7', 8', 9' and 10 in the right half of the peripheral area, cooperate with said boundary walls 1-3 and 3 to provide: along each front wall 1, a pair of front corner rooms 12, 12, separated by intervening space including a stairwell 13, 13; along each rear wall 2, a pair of rear corner rooms 14, 14 separated by a pair of back rooms 15, 15' and, along each side wall 3 (3') an outer bathroom 16 (16) and an inner transversely-extending bathroom corridor 17 (17'). The outer bathroom 16 (16) separates, and the inner corridor 17 (17') transversely interconnects, the adjacent front and rear corner rooms 12, 14 (and 12', 14).

Wall means in center area A fixed wall 20, extending longitudinally through the left and right halves of the center area, provides a closet wall 20 extending longitudinally from one bathroom corridor 17 to the other 17'. This longitudinally-extending closet wall 20 cooperates with the fixed wall means in the peripheral area to provide a pair of similarlyextending corridors, namely front hall corridor 21 and center corridor 22, respectively, extending along the front and back sides of the closet wall. The front hall corridor 21 passes through a pair of access door- ways 23, 23, one for each of the front corner rooms 12, 12' and may be viewed as extending up to and interconnecting the bathroom corridors 17, 17' on the front side of the closet wall 20. The center corridor 22 passes through the center doorway 24 and left and right doorways 25, at oppo 4 site ends of the center corridor 22 so as to interconnect bathroom corridors 17, 17'.

Framing means Each of the (front-side hall corridor) doorways 23, 23' and of the (back-side center corridor) doorways 24, 25 and 25, is preferably provided with means (not specially indicated) framing its corresponding corridor opening. When the entire apartment space is to be used as a large two bathroom apartment, each of the doorways 24, 25 and 25' may be left open (or provided with regular access doors) so that the center corridor 22 is usable throughouts its extent, while one of the doorways 23, 23, in the front-side hall corridor 21, may be provided with regular access doors and the other with some form of removable non-access closure, such as a removable wallpanel structure designed for snug mounting within the doorway.

Since the entire apartment space may be optionally used to provide two smaller single bathroom apartments, such apartments must be separated. Therefore, in further accordance with my invention, each of the framing means for at least two (and preferably all three) of the doorways, across the center corridor 22, is arranged to receive a removable apartment-separating or non-access closure, such as a removable wall-panel structure (not shown) designed for snug mounting within the doorway. In place of a removable wall-panel structure, one may use a double door closure such as is shown in FIG. 2. Here double doors 26, 26' are removably mounted in said doorway 24 of the center corridor 22 to divide the entire apartment space into two smaller single-bathroom apartments of equal size. The location of the doors 26, 26 are indicated in FIG. 1B by a pair of dotted lines.

Alternatively, the said apartment-separating closure 26, 26' may be mounted in door way 25 to divide the entire apartment space into two single bathroom apartments of unequal size, the smaller one bath two room apartment being located entirely in the left half of the apartment space. On the other hand, if appropriate framing means is mounted in doorway 25, then the smaller of the two apartments may be provided in the right half of the apartment space by mounting said apartment-separating closure 26, 26' in doorway 25'.

Outside access to and from all apartments of FIG. 1B is provided through doorway 27 in front boundary wall 1 and left corridor 28 between fixed wall 6 and stairwell 13. This street-access corridor may, of course, be provided (on the right side of plane 44) by spacing fixed wall 6' from stairwell 13' and providing it with a doorway corresponding to doorway 27.

Kitchen utility connections Each of the walls 7, 8 of each bathroom 16, 16' is preferably provided with permanent (fixed) kitchen utility connections, which are indicated by drawing these walls in triple lines rather than double lines. With this dual utility connection arrangement provided in both walls of each bathroom, the kitchen may be located in any one of the four corner rooms when all of the apartment space is used as a large Z-bathroom apartment. When the entire apartment space is used as two apartments, the provision of dual kitchen utility connections in each apartment permits the kitchen to be optionally located (temporarily or permanently) in the front or back corner room of each apartment or in the front corner room of one apartment and the back corner room of the other.

Flexibility It will be appreciated that the fixed floor-plan dwelling unit shown in FIG. 1B is quite flexible in that it optionally provides (a) one large apartment, or (b) two smaller apartments of equal size, one on each side of lines 4-4, or (c) two smaller apartments of unequal size with the smaller apartment being provided on either side of line 44. Since the dwelling unit shown in FIG. 1B comprises 6 rooms and 2 baths, the larger apartment would be of that size, each of the equal apartments would have 3 rooms and 1 bath while the larger and smaller apartments would have 1 bath each and 3 rooms and 1 room respectively.

Naturally the use to be made of the rooms of any given apartment depends upon each particular occupant. In the large 6 room 2 bath apartment, for example, a front corner room 12 may be used as a living room, the corresponding rear corner room 14 as a kitchen and the 4 remaining rooms as 4 bedrooms or a den and 3 bedrooms or otherwise. Since the front corner rooms 12, 12' are fairly large, one (or both) of them may readily be partitioned into 2 rooms for whatever uses may be desired. Other rooms may be partitioned as desired, 1

The fixed basic floor-plan used in FIG. 1B lends itself to multifloor apartment buildings such as the three-level building exemplified by the lower level unit shown in FIG. 1A and the upper level unit shown'in FIG. 1C in combination with the entry level unit shown in FIG. 1B. It will be understood that the lower and upper level units of FIGS. 1A and 1C are, for all practical purposes identical to the entry level unit of FIG. 1B. The street corridor 28 of the entry level is not required in the lower and upper levels; hence fixed wall 6 in each of the lower and upper levels, is located immediately adjacent the left side of stairwell 13.

The fixed basic floor-plan, characterizing each of the units of FIGS. 1A, 1B and 1C, lends itself to modular construction, such as is proposed in U.S. Pat. No. 3,292,327. Thus each unit may be constructed in the form of 3 modular elements comprising: one front element; a back element; and a center element; each of said modular elements extending from one side wall 3 to the opposite side wall 3'. Alternatively, it may be constructed in the form of, say, 4 modular elements comprising: a left element along side wall 3; a right element along side wall 3; and two more or less equal parallel elements therebetween.

FIG. 3 MODIFICATION The flexibility of the fixed basic floor-plan described in connection With- FIGS. lA-C is further illustrated by FIG. 3 wherein two such basic units are arranged in sideby-side relationship and interconnected through a doorway in their adjacent side walls (i.e. their common wall 3) to provide: (a) one large 12 room 4 bathroom apartment; or (b) two apartments respectively having either 1 and 3 bathrooms or 2 and 2 bathrooms; or (c) three apartments having 1, 2 and 1 bathrooms; or (d) four apartments each having one bathroom.

The 6 room unit on the left half of FIG. 3 corresponds to the lower level unit of FIG. 1A; hence it bears identical designating numbers; thus, 12 and 12' in FIG. 1A are 12 and 12 in the left half of FIG. 3. The right half of FIG. 3 has the same basic 6 room, 2 bath floor plan as the lower level unit of FIG. 1A but some differences are dotted in. For the sake of clarity, the left and right side boundary walls of the right half of FIG. 3 are designated as 3 and 3", respectively, while its fixed walls, rooms and corridors are assigned designating numbers corresponding to those used in FIG. 1A except they are 100* numbers higher. For example, 12 and 12' in FIG. 1A are 112 and 112' on the right half of FIG. 3.

The wall 3' of FIG, 3 is provided with an interconnecting doorway 130 which, for interconnecting purposes, may be left open or provided with a regular access door. It is also arranged to receive a removable apartment-separating closure of the removable wall-panel type or of the double door type illustrated in FIG. 2. With the doorway 130 open or openable, the space between corridors 21 and 121 functions as an interconnecting corridor 131.

It will be understood that, in an apartment building, each half of FIG. 3 has the framing means, the kitchen utility connections and the flexibility of any unit constructed in accordance with the preferred embodiment of my invention, hence characterized by the fixed basic floor plane described in connection with FIGS. lA-C. In addition, greater flexibility comes from the fact that a single apartment may occupy space on both sides of center wall 3. Finally, it may be constructed in multiple level buildings and in modular units.

The FIG. 3 arrangement is well suited for use in college dormitories, military barracks, and other like segregated or unsegregated constructions requiring a large number of sleeping rooms or bedrooms rather than apartment units with kitchens. For college dormitory purposes, the large room 112' of FIG. 3 could be used as a common room or lounge or subdivided, while most (if not all) of the 11 remaining rooms, could be subdivided by (fixed, movable or removable) walls or partitions to provide a greater number of rooms to be used for various purposes, such as sleeping rooms, study dens, chaperone apartments, etc. Like considerations would apply to military base barracks where the largest number of sleeping rooms in a given unit is a prime consideration.

THE FIG. 4 MODIFICATION This figure illustrates that, the basic floor plan remains to a large extent unchanged when a wall, corresponding to wall 9 in FIG. 1C, is omitted to provide a larger corner room 14", covering the area normally occupied by rooms 14 and 15. Furthermore, if the FIG. 4 arrangement is located at the lower'or upper levels of a 3 level structure and if it is to be occupied more or less permanently by one family or one group, then the access door may be located at one end of the stairway, which connects it to the adjacent floor, or at a stairway landing between floors. Thus the doorway 134 in FIG. 4 is located at the stairway landing.

THE FIG. 5 MODIFICATION The FIG. 5 arrangement incorporates the basic floor plan in a single floor duplex having entrance doorways 137 and 138 adjacent the center of the front wall 1. In this figure, one wall 6" not only separates the front corner rooms 12 and 12 but it also may be said to eliminate the hall corridor 21 on the front side of closet wall 20 because it cuts that corridor in half and prevents direct access between the duplex units. This design however retains a high degree of flexibility because it retains corridor 22 which can be blocked off at its center to provide duplex units of equal size or blocked oif at either end to provide a small two room duplex unit and a larger 4 room duplex unit. The dotted lines in rooms 12 and 12' represent kitchen equipment and a partition wall and in room 15 represents a partition wall.

FIG. 6- MODIFICATION The arrangement of FIG. 6 illustrates the same basic floor plan in a single dwelling unit having a single front entrance doorway 140'. The advantage of a unit of this type resides in the ease with which it can be converted into a duplex unit of equal or unequal size. For example, a conversion of this character into duplex units of equal size requires only the provision of another access doorway 140, the installation of a removable apartment separating closer 26, or 26" in doorway 24 and the installation of another like apartment-separating closure across corridor 21 at a doorway designated 141.

MISCELLANEOUS While I have described and illustrated the provision of outside access through the front boundary wall 1, it will be appreciated that outside access may be provided through the boundary walls wherever desired, but access through the front half is preferred over access to the back half. The precise location of outside access normally is a matter of choice for the designer; hence, a particular location of access is not essential although, again, centrally-disposed outside access through the front boundary wall is normally preferred.

Also while the kitchen utility connections preferably are located in the front and rear bathroom walls, it will be obvious that they may, in some cases, be advantageously located in an adjacent portion of the adjacent boundary wall.

In FIG. 3, a common wall 3 between units with an interconnecting passageway 130, as shown, is preferred. However, spaced walls 3', 3 for the left and right dwelling units, respectively, may be employed with an interconnecting tunnel-like passageway therebetween.

In FIG. 4, the left end of the back-side corridor 22 may be separated from back corner room 14" by a partition.

In FIG. 5, the wall 6 may be provided with a removable room-separating closure across the path of the frontside corridor 21 for conversion purposes. The same is true of FIG. 6 at doorway 140.

In this application, I have spoken of a rectangular center area. This, however, is not essential. As will be obvious, it may be of oval shape or of any other convenient equivalent shape. Likewise, the wall 20 in the center area is referred to as a closet wall. Again, it will be obvious that a wall having closets may be desirable i but not essential. Any desirable form of separating wall in the central area may be used as the full equivalent of closet wall 20.
