The Triangle
A bold silhouette that still settles into the garden.
Overview
A bold, architecturally striking design that stands out while blending beautifully in any garden.
The Triangle is the most architectural building we make: a sharply angled roofline that reads as a piece of design in its own right, rather than something tucked away at the end of the lawn.
It is built to the same standard as every other model in the range, so the drama is all on the outside. Inside it is the same insulated, year-round room.
