load bearing walls

how would you know where the load bearing walls are on a bungalow are they in the middle of the property
and how far do the steel beams need to go into the brickwork on either end to create an opening and does it need to be supported vertically too

"You can look from above in the loft to see if a wall is supporting the ceiling rafters.
12inches into the walls"

"if your joists in the loft run across the top of the wall its load bearing if the joists run the same way as the wall and there is nothing on the wall its not load bearing"

"Hi.

It depends which way the rafters are positioned in the loft.

Minimum requirement each side of the wall is 150mm for the still to seat on the padstone"

"Hi, please check whether walls follow in the loft as this will tell you whether they are load bearing as purlins may be sat on them for roof support. also steel beams as per new regs it needs to be 150mm minimum bearing on either end. A structural engineer will advise whether posts are required."

"Hard to answer without seeing the property however the steel is likely 150mm bearing onto a pad stone, vertically depends on the span, structural engineer is likely needed to assess"

"Load-bearing walls are usually thicker. You can use a special tool to determine the main location of the beams."

"You would need to enlist the assistance of a Structural Engineer for this kind of work. Building control would have to sign this off as competently done as well. Anything Structural is a notifiable element of building works. Each job will be designed for the building it is in so the load bearing elements of how far it goes into the wall are outlined on the design too. Should you want to see the property then this will also come up at that point. I hope this answers your question."

"All masonary walls are load bearing , the amount of wall above determines how much and the roof structure can determine not only load being beared but also the push and pull . Removing walls requires a specialist to determine not only the effect of load that needs supporting but the effect it can have on the splay/spread it could cause to the roof. Generally in bungalows internal walls are also masonary and act as walls ties holding the spread of external walls but don’t necessary support anything above . If your walls are timber it’s unlikely removing them will cause any issues . Steel beams should be a minimum of 150mm over brick or block and the supporting bed should be assessed to be a strong enough for compaction."

"On a bungalow, your load-bearing walls are usually the ones running through the middle of the house, front to back or side to side, because they’re carrying the weight of the roof structure. yes it needs to be supported vertically and should sit properly on both side the steel beams"
