Building models allows you to make a smaller version of a building that contains all the architectural elements that the real building contains. Using cardboard is one of the least expensive and least time-consuming options when it comes to creating models of buildings. Creating a school with cardboard allows you to customise the design to fit your personality and design vision in a short time.

  1. 1

    Lay a 10-by-40 inch section of cardboard horizontally on a flat surface. Measure and draw a vertical line every 10 inches along the length to divide the cardboard into four 10-inch sections.

  2. 2

    Place the straightedge vertically across the cardboard along the line created at the 10-inch mark and score the cardboard with the craft knife. Repeat this with the remaining three 10-inch marks.

  3. 3

    Fold along each scored line to create a four-sided box structure. The scored lines should be on the exterior of the box. The cardboard should bend easily, allowing you to form the cardboard into a four-sided structure.

  4. 4

    Tape the joining edges together inside the square, using three pieces of tape. One goes along the bottom edge. One goes along the top edge and one goes in the middle area.

  5. 5

    Place a 10-by-10 inch cardboard square on a flat surface and place the straightedge through the centre, connecting two diagonal corners. Cut along the line to create two triangles.

  6. 6

    Place your cube structure on a flat surface. Hold the triangles on the top edge of the cube and mark any overhang on the triangle corners. Cut off overhang with a craft knife.

  7. 7

    Place a triangle along the top of the cube along the interior side of the front wall. The point of the triangle will face upward. Move the triangle down slowly until the cut edges are no longer exposed. Tape it in place to secure the triangle to the cube. Repeat this process with the back wall of the cube.

  8. 8

    Place the 10-by-24 inch section of cardboard horizontally on a flat surface. Measure in 12 inches from either end to determine the centre location. Place the straightedge vertically at this mark and score the cardboard with the craft knife.

  9. 9

    Fold the score line in to create a 90-degree angle. Place the 10-by-24 inch cardboard over the top triangles on the cube with the scored line lining up to the centre point of the triangles.

  10. 10

    Pick the cube structure up and tape the roof to the walls and triangles from the interior of the cube.

  11. 11

    Draw doors, windows and a school sign onto the cube with a pencil.
