Why Choose Outdoor Freedom Rooms?

We use premium Nordic/Baltic Spruce

These softwoods thrive in the cold northern regions of Europe and grow more slowly than standard spruce, pine, or fir, resulting in 6 to 8 times more growth rings. Spruce features a finer grain and fewer, smaller knots than Pine, though both types are lightweight and easy to machine.

Comes with a 5-year anti-rot warranty

It includes a 5-year anti-rot warranty that begins the moment your order ships. This covers issues such as glass or hardware seal failures, wall log splitting, or faulty components.

Unloading is included in the delivery

Receive your new log house hassle-free, our delivery service handles the unloading at no extra cost.

Fast delivery for in-stock items

Have your freedom rooms delivered right to your doorstep! In-stock models arrive in 10–12 weeks.
