The Mousetrap

As presented at the Forestburgh Playhouse (Forestburgh New York),
Summer 2003

The scene, as described by Agatha Christie

The Great Hall of Monkswell Manor. Late afternoon
      The house looks not so much a period piece but a house which has been lived in by generations of the same family with dwindling resources. There are tall windows up C a big arched opening up R leading to the entrance hall, the front door and the kitchen; and an arched opening L leading upstairs to the bedrooms. Up L leading off the stars, is the door to the library; down L is the door to the drawing-room, R is an open fireplace and beneath the window up C a window seat and a radiator.
      The hall is furnished as a lounge. There is some good old oak, including a large refectory table by the window up C, an oak chest in the entrance hall up R, and a stool on the stairs L. The curtains and the upholstered furniture -- a sofa LC, an armchair C, a large leather armchair R, and a small Victorian armchair down R -- are shabby and old fashioned. There is a combined desk and bookcase L, with a radio and telephone on it and a chair beside it. There is another chair up RC by the window, a Canterbury containing newspapers and magazines above the fireplace and a small half circular card table behind the sofa. There are two wall brackets over the fireplace which work together; and a wall bracket on the L wall, one L of the library door and one in the entrance hall, which are also worked together. There are double switches L of the arch up R and on the downstage side of the door down L, and a single switch on the upstage side of the door down R. A table lamp stands on the sofa table.

The Design:

The majority of your set should be designed using standard stock flats.

Document your design on graph paper using a pencil and straight edge. Include...

  1. A Floor Plan. Scale: 1 square = 1'0" (You should only need one sheet of graph paper for the floor plan)
  2. A Flat Schedule of the entire show including the backing flats. Scale: 1 square = 1'0" (You will need at.least two sheets of graph paper)
  3. A colored Designer's Elevation of one wall of your set. You may use any color media you wish. Select a wall which contains either a door or window. Scale: 1 square = 1'0"


A few suggestions...

Link to Introduction to Theatrical Drawing and Drafting Techniques for more detailed information on theatrical drafting.

  1. Step #1: Develop a Floor Plan.
    1. On a sheet of graph paper, draw the floor plan of the stage.
    2. Use the playwright's description of the scene to establish the location of doors, windows, step units and furniture. Start by
      1. Layinig in the walls of your set.
      2. Cut the openings for the doors, windows and arch ways.
      3. Add the furniture. Remember, draw everything to scale.
      4. Re-draw if necessary.
    3. Draft your drawings in pencil.
    4. Use a straight edge -- a ruler, triangle, even an envelope. No wiggly lines. please.
    5. Make a "measuring stick" (or scale) from a narrow strip of graph paper. You will use this scale to measure the length of diagonal lines.

  2. Step #2: Layout the Flat Schedule using the flat widths established on the Floor Plan.

  3. Step #3: Develop and render your Designer's Elevation. You may use any media with which you are comfortable. If you are not an art major, may I suggest magic marker, colored pencils are even crayons instead of the more traditional water color paints.
