An FD30 approved fire door in the increasingly popular Amsterdam style with 3 vertical panels cut into a piece of solid core engineered timber. These doors are primed smooth grey. They could even lend an element of modernity to a more traditional decor, with the chamfers on the panels lending a subtly classic look to an otherwise very minimalist door.
We would recommend using a joiner with expertise in fire doors, as if they are not hung correctly, the fire safety features, which halt fire and smoke for a minimum of 30 minutes, could be compromised. There is also a 3mm allowance included on these doors for trimming, so you should be able to achieve a decent fit without compromising the fire door itself.
