you want one of these or similar for your drain cover.
New! Fully Galvanised 600 x 450 x 43.5mm Sealed & Locking Recessed Manhole Cover - Recessed Covers - Manhole Covers | RecessedManholeCovers.co.uk
I think you are doing right approach with timbers, boards and hardiebacker. Is this going to be used for cars....if so - you wanna be totally sure on no movement before you start tiling....timbers bolted to floor deffo.

I would't be driving on a timber tiled floor. If it's used for cars as opposed to a games room then sand cement screed to desired height.
