What a pod actually solves
A barrel wastes its corners. The curve means the bench meets the wall at an angle and the space above your head at the sides is unusable. A pod keeps the rounded shape, because curves shed water and heat evenly, and squares off enough of it to give you headroom where you are actually sitting.
The shape is doing work
The MiniPOD's raindrop profile is not styling. The peak carries the headroom and the slope pushes hot air back down over the bench rather than letting it sit against the ceiling where nobody benefits. It is 85 inches square and still seats four, which is the densest use of a small yard we sell.
The Luna takes the other approach: rounded corners rather than a barrel curve, which buys usable headroom along the walls.
Roofs differ more than the photographs suggest
The MiniPOD carries three layers, cedar planks, then an ice and water shield, then a black Cambridge asphalt shingle. The Luna uses an EPDM rubber membrane under its cedar. Both are built to sit out in weather, and both are worth understanding before you put one under a tree that drops sap.
Check the heater options before you fall for one
The MiniPOD takes a wood burner or an 8 kW electric. The Luna is electric only at 6 kW, so if the appeal is a fire in the garden with no circuit run, the Luna is the wrong one.
Smallest footprint, not smallest capacity
Pods are the ones that fit where a barrel or a cabin will not, and they do it without dropping to a two seater. Both Canadian Timber pods seat four. If the constraint is the size of the yard rather than the budget, start here.
Worth having a licensed electrician confirm the circuit before you order. These are the manufacturer's own figures and we are glad to talk them through or send them straight to your electrician. What your panel can actually carry is the one part nobody can see from here.
