structural integrity

Hey fellow builders! I’m working on a decking gazebo area, roughly 7m x 2.4m, with a pitched gable roof at 13°. I’m using 150mm x 150mm posts, concreted in 600mm deep. The decking joists, roof rafters, ridge beam, and all joists are 150mm x 47mm C24 treated timber. The roof will have 18mm...

Dear all, I live on the top floor of a block of 9 flats, and am quite tired of the mismangement and neglect that this building has been subjected to over my 2 years of tenure here. So I have over the last couple of months, managed to rally most of the building's rather inactive and dormant...

Hi all, Looking for some help/advice re: if I can move some beams in a single skim brick garage pitched roofup to give more height in room. The room is 4x2.5m and is in good quality. As it's a fairly small room i dont want a flat root (even though it passes building regs re: height after...

I need to hang a radiator (160cm wide, 50cm high, total weight around 35kg) via two brackets to a plasterboard wall. The wall is external, so that it has studs (about 12mm deep and 50mm wide) behind the plasterboard and then bricks behind the studs. I am lucky enough to have studs in...

Afternoon guys, I am opening up an old chimney breast that was blocked up years ago. The reason is twofold - ventilation (it wasnt vented!) And decoration. The new opening will be 400mm wide x 600mm high which is smaller than the original so I'm only knocking out 'infill bricks' and not any of...

Hi I'm building a den for my children in the garage roof. Before I go any further I want to hire someone to take a look and tell me whether the garage structure will take the weight. Can anyone advise me please on who I should be getting in touch with? An architect? Structural engineer...

Hi all, I'm planning on surrounding my landing with a stud wall (replacing what was a banister). If I were to build straight off the existing outer joist (below where the previous banister sat), I would not meet the 900mm minimum width required for building regs. The width of that section of...

Hi all, I want to replace the banister around my landing upstairs with a couple of stud walls so I can essentially create a separate enclosed space upstairs. Part of the stud wall that needs building cannot be built directly on top of the existing subfloor, as there would not be enough space on...

I had to remove portions of the existing subfloor chipboard panels (18mm depth), which now I need to replace (I already bought a new P5 panel). The problem is that one edge of the hole is irregular, and I'm worried that parts of the new chipboard won't have sufficient resting contact with the...

We recently started our loft conversion in a terraced house. The contractor followed the plans based on a calculation that was provided by a structural engineer. The work progressed to a level that three steam beams were put in place and by this time we heard back from the council building...

Good evening, I'm in the process of ripping out our pantry, putting in a suspended floor and fitting an understairs toilet. I've read around a bit and looked on a few forums but can't seem to figure out what is supporting our landing, aside from possibly the door frame to the pantry below which...

Hi everyone! I'm new here and a new homeowner. I was recently in the attic trying to drop an electrical wire to add a new light switch. In a rush and not thinking, I started drilling a hole in the exterior-facing ceiling joist with a 7/8" spade bit. After drilling ~2" deep, I stopped and...

So we had central heating installed and were later told that the plumbers had cut through the joists when they shouldn't have- the floorboards were essentially resting on the pipes etc.... So then somebody came along and drilled holes through the joists under the cuts to feed the pipes through...

I purchased a property a few months ago that had an internal garage knocked through to extend a lounge. This involves removing a load bearing wall and installing an RSJ. The work was completed four years ago and has a buildings regulation completion certificate. When purchasing the property I...

Hi, can anyone tell me if the wall in the photos looks structural? I think its just a frame that they put up for plasterboard as all the pillars in the property are concrete, and this is a small WC that i'd like to remove, i'm guessing given the way the timbers are just crudely joined at the...

I am in the U.S. I need to replace an exterior porch corner post/column. The column I am replacing is on a first floor porch which has another porch above it and the second floor porch has a roof over that porch. The house is 100 years old and the existing post/column is made from four 1x6...

Hi all, New to the forum, but I have joined as I have no idea what is going on here. I'm looking to open up a hope between my kitchen and living room, we live in a 1940's council block, the kind with the sash windows and walkway. Obviously want to get permission from the council, and today I...

Afternoon all, any help or advice would be greatly appreciated welcomed. We live in a 1930's semi detached. Upstairs floor/bedrooms above the lounge appear to be level, however the lounge is sloping towards the other semi attached to the side of the house. The sloping begins half way across...

Been looking at a property that is pretty cheap to be fair - the vendor has been honest (up to a point) about some structural problems. He said that the slate roof was taken off in the 1980s and replaced with a concrete tile but obviously the woodwork in the roof was not suitably strengthened...
