A dormer is a structural element in architecture that protrudes from a sloped roof and allows for additional space. If you're a tiny house enthusiast, the words "additional space" in a tiny house article might seem oxymoronic. Yes, owning a tiny home means that you are "okay" with small spaces, but there is no reason that you should have to sacrifice comfort in your tiny home.
So let's learn a little more about dormers and what they could do for your tiny house loft.
Some tiny housers love the coziness and lightweight option of the un-dormered loft (keeping the triangular gable roof line throughout), but most prefer to have a little more headroom. Dormers provide extra space for comfort and additional windows, while keeping the lovely visual aesthetic of the rest of the tiny home.

How much space do you really gain by having dormers? In order to visualize how much space is actually gained by adding dormers, you will need to have a basic understanding of roof pitch.
Roof pitch is described as the vertical rise divided by the horizontal span of a roof. The gable roof in our Elm and Cypress models have a 12:12 pitch, while our lofts with dormers have a 3:12 pitch. It is important to maintain some roof pitch for weather runoff.

An older Tumbleweed model, where the 3:12 pitch returns to 12:12 for the last few inches of the loft.
If you peer into the back of this older Tumbleweed's loft, you can see where the 3:12 pitch returns to the triangular gable roof line (12:12 pitch). This is a great way to visualize the difference between these two roof pitches.
If the above loft DID NOT have dormers:
- The roof pitch would be that triangular slope throughout
- The four windows that line the sides of the bed would be lost
- The space on either side of this queen bed would be lost
- A king bed would not be possible (only possible with dormers)
- The use of a staircase would be rather difficult (a ladder would most likely be used instead)
