This set of plans looks at the build-up of a garden room with a cold roof structure. With a cold roof build-up, the insulation is fitted between the rafters. A continuous air space is needed above the insulation; these plans show how this can be achieved. Even if you are thinking of a different size garden room, these plans will give you insight into the build-up of a well-specified building.

Steel faced insulated roof panels are popular in garden room design as they remove the need for rafters, so they are quick to install. Insulated panels are a sandwich of two layers of colour coated steel with rigid insulation in-between — the steel layers forming the final interior and exterior finishes. Even if you are thinking of a different size garden room, these plans will give you insight into the build-up.

This set of plans looks at the build-up of a garden room with a Warm Roof structure. With a warm roof, the insulation is positioned above the rafters. This is a popular option as it doesn't need ventilation, and the system makes it easy for fitting downlights in the ceiling. Even if you are thinking of a different size garden room, these plans will give you insight into the build-up of a well-specified building.
