Garage side door

Existing owner blocked up the garage side door. I am wanting to put door back in. Lintel is still there, so just matter of cutting out the space. Problem I am finding is its quite small width wise. The gap once cut would be 2030mm H x 830mm W. I was looking at some second hand doors and seen a decent solid wood one for a bargain, but it is 1965mm H x 830mm W. I believe it can be cut smaller width

My question is, what about the height. How much of a gap can work for above door for frame. I would have to build frame etc myself so can custom make it.

Hope that makes sense.

Isn't finding a door, then the frame, then cutting the hole out in the masonry to suit, doing things backwards?

The reason that door is a bargain is because it has already been chopped to death.

Look at standard door sizes, standard frame sizes (masonry opening size) then decide on your opening etc.

30" (762mm) and 33" (838mm) are standard door width sizes.

78" (1981mm) is a standard door height. You may need to decide if you are having a sill or no sill on your frame.

Faffing about trying to make everything suit a second hand - chopped to death, door is a crazy way of going about things.

The size of the hole for the garage door is fixed, I wont be changing that as the Lintel is still in place. It has been purely bricked up.



Buying a new door with frame is silly money. Trying to use a 2nd hand door may seem like faffing around to you, but its what I am trying to do. This door is probably too short anyway.

I was hoping someone could tell me what sorta gap can you get away with for a door frame/sill.

Just buy a 30" wide door. Nothing else will fit in that gap.

Height wise, you can add a timber knock-on or an architrave to the frame head or buy a frame with a sill.
