House With a Garage
Hello Builders,
My name is Mr. Savage. I am  building a house and a garage. I will keep my four wheel drive matchbox truck inside the garage. Do you have a  garage for your truck?

Would you like to build a house with a garage? Before you begin, first make a( cardboard cubic decimeter) and a (tetrahedron).

Making these two structures will give you skills. These skills will help you make the house, the roof and the garage.  
Getting Started
This is my  house plan. I used this template to make a cubic decimeter. The plan for the house and the cube are same, but the house does not have a top. The top centers the roof on the house so it is glued to the bottom of the roof. I'll show you how later.

Top
I chose a piece of cardboard from my cardboard supply. I placed my template on top of the cardboard.

I used a marker to outline the five parts of the template I will be using for the house. The top is outlined with a pencil. The top will be used later.

I used a canary knife to cut the cardboard. It is a safe tool to use. You could use a utility knife but it is dangerous and you will need
adult supervision.

Bending the Sides
Roll a screen roller lightly along the bending edge where the sides and  bottom meet. This is a safe tool. A utility knife can also be used but it is much more dangerous.
Gluing the Sides
Masking Tape
Glue Gun
Gluing the Four Edges
Cut four short pieces of masking tape to temporarily hold the four corners in vertical position. After heating up the glue gun, I ran a bead along each of the four seams. Caution, HOT! Wear Safety Glasses! Adult supervision recommended!

Note: Four sides and a bottom, no top.
The roof is made exactly the same way as a tetrahedron. This time the base is a 14cm X 14cm square.

The four triangles are congruent isosceles triangles and the base is a  a square with 14cm sides. I used boxboard as a drawing material to design the roof.

A compass was used to make the triangles. A compass is difficult to use so  Practise! Practise! Practise!

Radius 11cm
I  design three different square based pyramids house roofs. I used large boxboard cereal boxes to make my designs.

These designs can be cut with a pair of scissors, folded and rolled. The final shape can be held with masking tape.  Collect cereal boxes, the bigger the better.

After examining  each of my folded designs placed on my house I chose my final design.

Teachers: I transferred the design to a piece of thin Masonite board and cut cut the shape on my band saw. I used the final design to make a strong permanent template. This design is great for demonstration purposes.

Advanced Students: On one of the isosceles roof template triangles there are four holes. These for holes will help you make a dormer.

A dormer is an interesting design addition to your house. This design can be rotated 90 degrees, three times to add up to four  dormers to your house. You can decide how many dormers you want.

Making a dormer is difficult so practise on a scrap piece of cardboard.  Place the template on some cardboard and using a sharp pencil through each of the holes mark and join the points together with a ruler.

Cut two of the shorter sides and one of the longer sides. Using a roller, roll and bend the last side. You may have to try two or three times but you will succeed.

The Garage
There are two cardboard parts to the garage, the frame and the roof. This is a  good test for you. I am not going to tell you how to make the template. Use one centimeter graph paper to make a plan.
