Knocking two rooms into one

[BernadetteRostankowskiWolowitz]

Got a smaller room off our lounge I'd like to knock through and make a living/dining room. It's currently used as a home office which we could relocate, but we spend most of our time in the living room so that's what we need to make bigger.

Anyone recently knocked rooms into one, do you mind sharing how much you spent?

The works would be:-
Knocking down wall
Adding a joist (presumably but would check if needed)
Blocking up a doorframe
Recarpeting
Making good plaster/paint
Rerouting some sockets

Is there anything in the wall? Plumbing? Gas? Electrics?

Only thing in the wall is one double socket and the light switch for each of the two rooms.

There's a real lack of sockets in both rooms so it would he a good time to sort that out too.

Yep, you will need an electrician in to remove the wiring before knocking the wall down.

New skirting boards and floorboards.

If adding new sockets on top of blocking up the door elsewhere would you be happy to skim and paper or would the entire room need plastering?

We have recently renovated and knocked down walls and needed supportive steels. I can't recall the exact price as we had several put in, plus lots of other work. Even IF I could find the paperwork, its irrelevant. When we booked the steels- we were given 7days to pay because the price of steel was going up that quickly at the time. This was about 10mths ago- so don't know about now. Sorry.

Do consider how long the steel would be and access to the property. We have the width of a double drive way on one side of the house, and they were able to back up the truck and use a dolly to maneuverer the steels in.

Neighbours are also renovating- but their access was via a gate only. They had to pay for a crane to carry the steep up and over their house!!!

Get recommendations/quotes from other trades/builders you trust.

Lots for me to think about here. Thanks!

You might want to check to see if you need a building regulation’s certificate for the work especially if a load bearing wall, chimney or connected to stair case. You’ll need this also when you come to sell the property in the future.

If I was to guess. I’d say probably around the £2k - £2.5k mark for the work to be done. Cost of materials and labour. I would get a few quotes though first - cheap isn’t always necessarily the best though - you’d want a proper job done.

I'd guess it could be way more than £2k. We had a quote for a garage conversion- not too much to do beyond creating a wall with a window at the front and then pretty much internal stuff ( although blocking up one door and creating another, and moving a radiator along with the internal plasterboarding and flooring) but that was £25k. We still have a garage!

I recently had a company come in to do this in my house. (Ok i did the electrics) but it cost me £14k this included a 5m concealed RSJ, new flooring throughout my downstairs to match, new stud wall built with a fire door. and a lot of plastering and painting after

Building work and materials has gone thru the roof.lll.I would say at least £5k still probs more

Really depends if it’s a load bearing wall or not

You'll need to employ a structural surveyor to carry out load calculations for you, building regulations and then the builder and team, RSJ etc. Plus finishing works, plastering and electrics.

For these works, depending on patching your floor level, £3.5-£4k.

NB if it's a load bearing wall.

This figure is closer to the mark I think . We’ve recently gone open plan between 3 rooms, with steel beams involved and the cost of everything has been eye watering.

Our structural engineer alone was £750!
