Hardwood/Softwood door?
Half glazed or just a small window in the centre of door.
Door frame for 33" door with cill & weather strip, last one cost me £69, 5 lever euro lock another £20 or more depending on brand & quality, & a softwood 2XG door cost me about £90, your still to add door furniture,hinges, finish to door, & carpenter's fitting costs.
Better to look at GRP Composite External Door, or UPVC door, as they come finish in a pre-hung with either a PVC-U or hardwood outer-frame. & with 3 or 5 point locking, never need painting,usually come with a 10 Year Guarantee.
