I'll get the builder to look at the pillar however we are unable to move the door frame to the right as the stair well begins on the other side of the door.

Coming back to the point around skirting with no architraves for this particular door against pillar, should the skirting be done this way or not wrap around the pillar at all?

If the door does not lead to an outdoor area.......appears it leads to a hallway.....why do you NEED a door to the lounge, which I assume means living area? It looks very narrow even with no door! Old homes had doors to virtually every room for heat and draft control.......doesn't mean you must in this day and age.Simply......don't return the skirting on the post....just straighten the post : )

Looking at the photo it would appear the pillar is completely miss aliened and is showing quite a large bow from the bottom to the top. I would be checking the pillar is sufficient to carry the weight of the ceiling now the wall has been removed. The bottom needs moved to the left by at least a couple of inches. If this was done the skirting could be run up against the door frame which would be the natural place to finish the skirting. You could remove all the skirting from the pillar but I don't feel it will look right as I assume the pillar will be repeated on the opposite side of the room.

Thanks Jan, the reason to have the door is to primarily retain the heat in the lounge which is 8 x 4 metres. The door frame and the door already existed when we bought the property so we are trying to retain the current layout. The wall which the door frame is not flat but is at a 15° angle.

The existing beam and pillar has been there since the 1900's and according to our surveyor is structurally sound, however I do take on your point about the slight bend there.

I've just added two more photos so you get a front profile view and an idea of the opposite side.

Just wanted to show you the below image which was something I had in mind for the door. Again plain white walls, hard wood floor and a wooden door which sits flush to to the frame of the wall. Now I know that there is no skirting here but in our case we wanted to retain some of those Victorian characteristics.

If the door/heat loss is that important, I would consider two very NARROW doors...and let them swing into the hall vs, into the room.....or something totally unexpected on the hall side such as an intentionally modern slab "barn" door arrangement, wood on a sleek iron rail. The doorway will feel much less crowded and narrow. Even a slab pocket door if it had been considered at onset of renovation could have worked

We did the baseboards or skirting around the archway floor at the back of this picture because we did not have a door there anymore so I would not replace the door and wrap it around the whole pillar. This house was built in 1905 and we replaced a lot of the features that had been removed but kept a modern feel to the space.

I;m with you Patricia! But he's trying to "preserve heat " in the room....

Do you have central heating in the house? If so, I think leaving the door off would help with airflow. If there are still coal "fenders" in each room, then you want to keep the heat in each room. That is to say, I assume you're from England, due to the different terms you are using.
