The Criteria Matrix
• The matrix format is a widely

used technique for visually
organizing information of a
variety of factors that is
sometimes referred to as a chart
or table.
• The criteria matrix is a useful

technique to condense and
organize the conventional
written design program.

• In its most basic form, the matrix is a rectangular grid of notation spaces with names of rooms or
spaces (or functions) listed in the column to the left and columns for verbal and/ or numerical
indications of program requirements in the succeeding columns to the right.
• A hand-drawn, basic blank matrix for a Sample

Design Program is shown the table on right side,
indicating notation columns for the most critical
space planning factors:
• (1) Square Footage Needs,

• (2) Adjacency Requirements,
• (3) Public Access,
• (4) Daylight And/or View,
• (5) Privacy Needs,
• (6) Plumbing Access,
• (7) Special Equipment,
• (8) Special Considerations.

Prototypical PlanSketches

• At this point, if the space-by-space square footage
requirements total more than the square footage
contained in the building shell, the spaces will not
fit within the exterior or demising walls.
• Conversely, if the space-by-space total is

significantly less than the square footage
contained in the building shell, the building will be
underutilized and is likely also to have awkward
and oversized circulation spaces.
• For certain kinds of spaces, the square footage

column may be filled in with relative ease and
speed. For example, if one has considerable
experience in office planning, it may be possible to
quickly respond to the program description of an
executive office, counselling room, or conference
room with an estimate of square footage needs.
The same may be true of almost any kind of typical
space, such as a reception room, kitchen, or public
restroom.
• The use of prototypical plan sketches will usually provide
the needed information with square footage area
requirements.
• For example, a design program may call for a director’s

office with a 36" x 72" desk, a matching sideboard, a
desk chair, two guest pull-up chairs, lounge seating for
four people, and bookshelves.
• In order to get started, it is best to take a few minutes to

quickly sketch one or more floor plans of such a room to
establish approximate size needs, as shown on the
Illustrations.
• Keep in mind that these quickly drawn sketch plans are

not intended to be directly incorporated in the floor plan,
but are meant primarily to serve as generators of square
footage requirements.

• It should be obvious that a basic knowledge of typical
furniture sizes, arrangements, and dimensional
relationships between individual pieces of furniture is
essential here; otherwise, one cannot work with
appropriate speed.
• Until you gain enough practical experience to have an

idea about basic area requirements and furniture sizes,
regular referral to standard reference sources and
furniture catalogues will be required.

• With the prototypical plan sketches completed, it is now time to go back to the criteria matrix and fill in the
square footage column for those spaces for which one was unable to estimate size based on previous planning
and design experience. But an element is still missing in the square footage figures — the space needed for
circulation (halls, corridors, vestibules, etc.) and partition thickness.
• For most non-residential interior facilities, a factor of 25 to 33 percent of the square footage total for all
required spaces will be a reasonably accurate estimate of the space needed for circulation and partitions.
• This factor will vary from project to project, depending on the configuration and construction of the building
shell and the nature of the functions to be performed in the space. However, 25 percent factor is practical for
most space planning problems because it permits one to err on the side of safety.

Adjacency Matrix

Relationship Diagrams/ Bubble Diagrams
• Bubble Diagram is a basic free hand drawing that

consists of roughly drawn bubbles (representing
spaces) connected by solid lines, broken lines or
wavy lines etc. to specify the type of relationship
between the spaces.
• Rooms or functions that are next to each other should be

drawn close together, while spaces that are not close to
each other should be drawn at adistance.
• Use connecting lines between the circles to indicate

travel or circulation patterns between spaces; those
connections should be coded by using heavy or multiple
lines for important or heavily travelled connections, and
lighter connecting lines between spaces where circulation
adjacency isless important or lesstravelled.

Block Planning
• Another well-established technique
for this initial step into physical
planning is conventionally referred
to as “block planning”.
• The process of development and

the results are similar to those in
bubble diagramming.
• Its primary advantage over bubble

diagramming is that the result is
more like a floor plan, and some
planners feel more comfortable
working with its more geometric
quality.

Exercise 05
Prepare an adjacency matrix for an apartment with the following functions:
• Entry Foyer
• Living Room W/Balcony
• Dining Room
• Master Bedroom W/Balcony
• Kids Room
• Guest Room
• 3 Bathrooms
• Powder Room (Optional)
• Kitchen
Additionally, you can propose any other functions that compliments the existing requirements.
