Cathedral Sunroom

A classic and timeless design, the Cathedral Sunroom is characterized by a high vaulted ceiling and a large glass gable that imparts a grand and elegant appearance to this style of room. Among traditional-roof sunrooms, the Cathedral style includes the highest percentage of glass in its design, allowing more sunlight in – producing rich, dramatic natural lighting. With LivingSpace’s custom design capabilities, the slope of the Cathedral roof and offset of the gable can be fully customized to carefully match the geometry of the existing roof, while preserving the unique architectural style of the home. Often used as a great room, this style of room is a popular choice for entertaining
