This model boasts a box section ridge bar, cast ridge and eaves joints, and extra bracing - all resulting in a stronger frame. Magnum models also enjoy an increased eaves height of 4ft 10ins, almost ten inches higher than other models in the Halls range.
Freestanding staging and shelves can be added to the Supreme range to make more of the space available, giving you even more room for growing.
We recommend upgrading to safety glazing to help protect you and your family. Ventilation can be improved with the addition of low level louvre vents and automatic roof vent openers.
