1. Interior Elevations

2. Interior Elevations
Used to describe the finished interior walls of a room
Elevation is based on the floor plan and the directional indicator pointing towards a particular wall are keyed from plan to the elevation
Common residential interior elevations
kitchen walls
fireplace
bathrooms
other cabinet work or built-ins
Commercial projects may show every wall in the interior of the building

3. Interior Elevations
Common scales, selection depends on amount of detail for the elevation
1/4” = 1’-0”
3/8” = 1’-0”
1/2” = 1’-0”
Templates are commonly stamped for various shapes at these scales, available from plumbing vendors

4. Interior Elevations Interior Elevation details usually include
basic structure - cabinets, appliances, window/doors, etc.
notes & dimensions, dimensions are usually in inches only (AIA practice)
electrical cover plates for outlets and switches
base moldings, trims, door/window casings, etc.
some hidden lines & section lines
some elevations will include sectional portions of cabinets
some complex items that cannot be fully shown on the floor plans can be shown in an interior elevation

5. Interior Elevation Directional Indicators and Drawing Notations
Floor plan will be keyed to each interior elevation with notations (keying symbols) shown below
The arrow indicates the direction of viewing the elevation
Top portion indicates the detail number, lower portion is the sheet the detail is drafted on

6. Example of Keying Symbols on Plans

7. Floor Plan Coordination with Interior Elevations
Notations on the floor plan coordinate direction of viewing and each interior elevation
Interior elevations A,B,C,D shown here

8. Standard Cabinet Dimensions
Lower/Base Kitchen Cabinets general dimensions:
36” high (floor to top)
34 1/2” cab height
24” wide cab
25”-26” counter top width
1” to 1 1/2” front lip
4” high x 3” deep toe kick
back splash - height size will vary, 4”-6” common

9. Countertop Styles
Materials of counter top vary and will be discussed later, some examples shown below:
Square Fillet Water-Lip Chamfer

10. Standard Cabinet Dimensions
Upper/Wall Kitchen Cabinet general dimensions:
” high
12” to 13” wide
Number of shelves will vary, fixed and adjustable are available
Soffit open or closed
13”-14” X 12”
Soffit {

11. Pre-Manufactured Cabinet Units
Lots of Manufactures - review their literature for specific unit sizes
Each manufacture has a code system to identify each cabinet unit
Generally width of Units are
greater than 7-1/2”
maximum size of 23” for single door opening
full unit commonly not to exceed 48”, there are exceptions

12. Standard Cabinet Dimensions
Distance between base and wall cabinet will vary
normally 16” to 18”
Total cabinet vertical distance (variations)
= 84 = 7’-0”
= 84 = 7’-0”
Open vs closed soffit (area above wall cabinet is 12” from cabinet to ceiling)

13. Interior Elevation Technique #1
Heavy thick outline or profile line to make the elevation standout
Omits the lines of the wall and floor behind the cabinets
Area behind cabinets are not included in the elevation

14. Interior Elev. Technique #2
Heavy thick outline or profile line to make the elevation standout
Shows the sections of the cabinets, etc.
Crossing lines to indicate space of cabinets, etc.

16. Drafting Guidelines for Interior Elevations
1) Determine true width of interior wall
locate all windows, doors, etc.
2) Determine wall height
usually 8’ unless vaulted
3) Draw the outlines of all cabinets, shelves, wardrobes, & plumbing fixtures which are to be built
locate stove, refrigerator, & other appliances

17. Drafting Guidelines for Interior Elevations
4) Select basic Technique
see handout
5) Draw outlines of varying wall materials
6) Mark off doors, drawers, shelves, toe space, and soffits
show hinge sides of all cabinet doors (use dash line pointing to the hinge side like casement windows
7) Draw in all base molding, and door & window trim
more

18. Drafting Guidelines for Interior Elevations
10) Place all electrical outlets in elevation
11) Letter all notes & dimensions
12) Letter titles and coordinate elevation with arrow keys on floor plan
13) Draw surface material symbols
14) Profile drawing as per technique

19. Interior Elevations - Pre-fab Cabinets/ Bathroom Elevations

20. Pre-manufactured Cabinets
Literature of manufactures local and nation wide will give specifications and ordering information, such as
Manufactures unit identification ( a code unique to each manufacture, such as: code + size in inches
examples of general categories of pre-made cabinets
wall cabinets = WC, WPT(wall pass thru)
base cabinets = BC, D(base drawer unit)
sink cabinets = SC, BS (base sink front)
appliance cabinets = AC
vanity cabinets = VC
utility cabinets = UC

21. Pre-manufactured Cabinet Section
Cross section and dimensions for “Marsh” furniture company High Point, North Carolina
Most manufactures will supply dimensions so other drawings can be coordinated with cabinets
