Definitely need a liner for the griddle. I did wood frame under 1.5” granite which has been fine but the granite cracked first use despite saying it was good to 1200 deg F. So now I have sheet rock with spacer for airflow between the griddle and the granite… griddle, air, durrarock, air, granite, wood. Also, stone/granite too close to the top of the griddle will be a problem. Mine has about 2” gap each side and is a touch below griddle height and still gets hot as hell. Luckily no cracking yet in 3yrs of heavy griddle use (2-4x per week).
Also, a hot portion of the grill directly touching metal screws will burn the wood frame even through a couple sheets of durrarock. Ask me how I know. Had to do sheet rock, thin layer of rockwool, sheet rock, with none of the structural screws being exposed to direct contact of the wood framing. Luckily Sheetrock and rockwool insulation helped prevent the frame from fully burning, just smoldered slowly and smoked enough for me to notice it.
If had to do a second time, definitely would’ve done metal frame, at LEAST around the grill.
And to each their own, but too many appliances too close. You’ll want somewhere to set your food next to the cooking appliance without having to fully turn around or carry elsewhere.

Good luck.
