Define how the room will be used
A seasonal sitting area differs from a room intended for everyday use as part of the home. Discuss layout, heating, ventilation, daylight and solar exposure before selecting the frame and roof system.
Compare materials in context
Timber, aluminium and uPVC offer different appearances and maintenance needs. Compare complete specifications, including glazing, opening sections and roof details, rather than frame prices alone.
Prepare foundations and the connection
Floor levels, drainage and the opening into the house need to be resolved. Structural assessment may be required where the existing facade changes. Check permissions for the address and design before ordering.
Budget for the full project
Separate design, foundations, supplied elements, assembly, services and finishing. Agree whether the room is delivered as a shell or ready for its intended use, and how remaining work is coordinated.
