Anyone know roughly how much to put a wall back up?

[Pollyoramge]

The opposite of what most folks have done over the last few years / decade but I want to separate my through lounge/diner now kids are older and now I'm WFH and have a desk in the dining room.
Doors would be ok or a full on wall again but I have no clue what it'll cost and need to save - has anyone got any idea of cost for this?
I looked at room dividers by b and q too but I'm not handy at all! Yet. I'm hoping to learn but don't want to bodge it

Does depend on if it's a stud partition wall or blocks, then with or without doors.

If stud partition it's fairly simple, timber frame (cost depends on how large) then plaster boards, plastering, skirting/architrave, paint wall (would both rooms need fresh paint to match in). Would flooring be ok to remove the area where wall would go back? If you had wooden floors or tiles through both rooms it will need slightly more work.

Single or double doors?
Have a think if noise reduction is important as stud partition wouldn't give great noise reduction but it's ok.

It does depend where you live but I would like around £2-3k if you had a decent general builder as shouldn't be a long job.

You also need to factor in lighting unless each area is separately controlled.

You need to get some quotes from local builders, I also find that builders usually have some good ideas from working on other projects.
If you go for a wall I'd definitely go for a false / stud wall, I think that'd be cheaper.
I've just had my garage door taken off, a wall put up and a door installed, think bricks either side, door in the middle.
If you think about the width of an average garage door which will be a lot smaller than the width of a room, I paid £600 for breeze blocks, bricks, sand and cement and some extra bits like insulation.
The door, regular size PVC, top half glazed was £900 installed.
Luckily, the builder is a friend, I paid £350 to him and £150 for his assistant and it took a day to do.
I've not had it plastered inside yet, my dnephew is a plasterer, he'll do it cheaper but both the bricky and my dnephew have told me that the increase in building materials is shocking.
If I were you I'd price up doors (bi-folds are my dream) then you could open them up if needed.
If you have a wall built and a door you'll also need to think about the damage to your flooring, if it's carpet they may have to cut it, add the cost of a new carpet into your savings plan.
Personally I'd do anything that didn't involve plastering, my dnephew plastered my kitchen, I'm still not over the shock of how messy a process it is 😁

Thanks for these. I'd not thought about flooring etc hence being so grateful to have the wisdom and experience of you lovely lot. I'll try find a pic. It's like an arch way right now. Doors might be easier

This is the floor plan from a neighbour's house that's for sale. Ours is same size just the mirror image
I'd keep the doors as they are but would like to put doors across that gap if a wall is thousands. Mind you doors won't be cheap either will they I don't imagine ! all feedback about this sort of project welcome

We had had half a wall built and double doors added so we didn’t lose too much light, and we had a wall moved up stairs, I think I paid just under 2k.
it was all stud and plaster board.

I think the plastering was the expensive part.

I’m not sure how successful it was as often the doors are left open. In hindsight I’d put a whole wall across, but I think it would make the room dark.

If you put a wall up won’t you have to put a door in too somewhere? (Assuming the front bit of the lounge is a bay window?)

Our old house had a wall removed between the 2 living rooms. We had the arch squared off and half glazed double doors installed. We had the best of both worlds - a big space for family get together, closed off for cosy winter evenings.
If you’re planning on using the dining room as an office, from that diagram people would have to walk through your office to get to the lounge.

OP: on the off chance you are getting alerts and see this, where did you get to? I’m at the beginning of the exact same set of questions!

@BunsenBurnerBaby If you add @ at the front of the name ie @Pollyoramge then they should get a direct alert.
