This is a job from a few weeks ago.
I had to build a substantial trap door for a cellar.
The customer wanted it so that it could be left down for most of the time and the room used like a cupboard, but good access for the cellar when needed.
I used some planed 6x2 timber for strength, adding a chamfer around all the edges so it gave it a traditional look. The hinges were brass, chopped in to be flush with the surface and a "bar" catch at the top to hold it open when you wanted to go up and down the stairs.
A relatively simple project that with the addition of a few things, like chamfers and brass fittings, looked really good when it was finished.
