Hi all,
I bought a new 3 story house 3 years ago and I am considering to remove a wall between the kitchen and living room in the ground floor, also I am gonna keep the other two walls protecting the staircase following the fire regulation. Each wall kept has a FD30 door.
I did a quick check around the house and the wall that I want to knock down it’s a 22 mm plasterboard and behind it, there is a plywood board (I don’t know why). It looks like it isn’t t load-bearing wall. See the mark in red in the attached images.
I checked the ceiling and all I-joists are wall-to-wall with a span of 5.3 Mts (approx.), and all of them are parallel to the wall in question. Also, there is a steel beam across the ceiling wall-to-wall and just 1.8 mts away from the wall. The steel beam is parallel to the wall needed and the all ceiling I-joist. See mark in green in the attached image to see the steel beam.
I am not really sure if I need an architect or engineer, what do you think ?
is it required to apply for planning permission or follow any building regulation ?
If I need planning permission, what probably do I have to get it accepted?
Any advice much be appreciated.
thanks in advance.
