How do I raise the level of a room?

[AnneM]

I’d like some advice on how to raise the level of our living room. Our living room is currently carpeted, while the rest of our house is tiled so when we rip up the carpet it’s 14mm lower than the rest of the house. We want to do the whole house in hybrid floorboard so need to level the living room. 

we would love some advice on what we should do.

Welcome to the Bunnings Workshop community @AnneM. It's terrific to have you join us, and many thanks for your question about levelling floors.

Laying STRUCTApanel 12mm 2400 x 1200mm H2 Non-Structural Panelling would raise the floor 12mm. That would allow you to use a transition cover strip. Since it's only a 2mm difference, you could use packers under the particle board at the transition and not use a cover strip. I recently had a similar difference in height on some flooring, and we were able to lay over the area without the need for a joint and strip. By using a 1.5mm packer under the particleboard, you can ramp it up to meet flush with the tiles.

Please let me know if you have any questions.
