Through our five distinctive conservatory pathways – each with unparalleled possibilities for customisation - create a stylish, truly individual structure that precisely meets your needs.

Design Your Dream Living Space

Castlegate’s Classic Plus takes the Conservatory to the next level. An ingenious perimeter roof pelmet accommodates downlighters, providing a focal anchor around the entire perimeter of the conservatory. The system can also accommodate brick columns and dwarf walls. To enhance the roof space we can create the appearance of a traditional Orangery – at a fraction of the cost.

What’s more, the Classic Plus roof is available to upgrade an existing conservatory. Most conservatory types are suitable, and the upgrade transforms an existing structure with minimum disruption and cost.
