How to build a Guinea Pig Hutch

Top and bottom frames | Front and rear walls

Step 1: Make the top and bottom frames

Out of 2×2 (50mm x 50mm) stock make two rectangle frames 26″ (660mm) x 46″ (1170mm). To both frames, add a cross-member 16″ (406mm) in from one end. On one of the rectangle frames fix a piece of plywood (the floor) 16″ (406mm) x 26″ (660mm), as shown in the picture and Plan 1.

Note: The sizes mentioned here are the nominal sizes (in name only). The real (actual) sizes of the wood will be less once the wood has been dimensioned (dressed, planed).
For example: 2×2 stock (nominal size) once dressed will be 1-1/2″ x 1-1/2″

Step 2: Fix the front and rear walls

Note: The front wall is 2″ (50mm) higher than the back wall.

Stand the rectangle frames on edge, parallel, and apart 17″ (432mm) overall.
Out of 1/2″ (13mm) plywood, cut the back wall panel to the dimensions given in Plan 2.
Fix it to the frames, ensuring one edge begins 1/2″ (12mm) up from the bottom of the bottom frame, and the other edge is flush with the top of the top frame.
Refer to the picture and Plan 2 for detail.

Flip the unit over.

Out of 1/2″ (13mm) plywood, cut the front wall panel to the dimensions given in Plan 2.
Fix it to the frames, ensuring one edge begins 1/2″ (12mm) up from the bottom of the bottom frame, and the other edge runs past the top of the top frame by 2″ (51mm).
Refer to the picture and Plan 2 for detail.
