    Does a horizontal soil pipe have to run within/below the floor slab?

    We have a new soil pipe entering the house with the top of the pipe sitting at the same level as the where the top of the slab will sit. To maintain the correct fall along 3m to the WC, it would have to rise by 75mm, which eats into a 100mm insulation layer (before 50mm screed goes on top) and...

    Garden Wall Foundation Size?

    Hi, I'm looing to build a single skin dividing garden wall 1m in height, with double skin support columns at regular intervals of around 1.6m in height. I'm building right up to my boundary, so some of the footing will need to extend into my neighbour's land, and I'm trying to determine how much...

    Can Steel concrete casing form part of floor slab?

    Hi, More for my understanding and planning right now, but my wraparound extention is set to have a box frame steel beam running below the floor (where the wall will come down), right down the middle of the room which will be encased in 100mm concrete. My question is, can the top of that...

    RSJ Box Frame Depth

    We are on an old Thames gravel bed, which it pretty much sand and small pebbles, so that may account for it.

    RSJ Box Frame Depth

    Full box is what our SE says we need. It’s 8m long and 300x300mm beam, so quite considerable. It’s just supporting one floor above. Funnily enough, the same size beam will be at the top holding up the house with no support all along it, other than the pillars at either end, so hopefully a 300mm...

    RSJ Box Frame Depth

    Thanks. It will sit on the existing concrete foundations of the wall it’s replacing, but once cut down to the required depth for the steel, the foundations will be around 300mm deep. Fingers crossed that will be enough, as I wouldn’t want to have to dig those foundations out completely and redo...

    RSJ Box Frame Depth

    Hi, My upcoming wraparound extension calls for a (8m long and 305mm square) Steel box frame to support the 1st floor side wall where it is being knocked through, but I'm trying to understand how deep the bottom Steel needs to sit in the ground? My solid floor will consist of 150mm compacted...

    Plaster 'up to' cement board/tiles or plaster all befor tiling?

    Hi, I have a dividing metal stud wall along one side of my new bathroom. One small section of it will be in a walk in shower so I'm cement boarding and tiling that area, but the remainder of the wall (divided by the vertical line of the shower screen) will be moisture resistant plasterboard...

    Is this electrical work up to scratch?

    Hi guys, and thanks for all your comments. The single insulated cables all appear to be earth cables that he's gone from green, joined to brown, then to blue because there was not enough green. Luckily I've not paid a penny yet, and certainly won't be paying full price.

    Is this electrical work up to scratch?

    Hi, I've just had some electrical work done after a meter move, to install a new fuse box and reconnect 6 existing circuits plus electric shower in a new location. It's all a bit of a temporary job until the house is fully rewired in the next 12-24 months time. I'm a little concerned about...

    Metal stud basement wall thickness?

    Hi, My basment is being professionaly tanked, and I need to install stud walls all around, before insulating/plasterboarding. I'm looking at using 50mm metal studs 400mm apart, with 12.5mm plasterboard (700mm on some walls, but space is an issue, hence wanting 500mm if possible). Some...

I am installing metal stud walls to the edges of the room that will be insulated but only plasterboarded on the one side, so I am concerned about the strength/possible felixibility of the wall as it will be approx...

    Air ventilation bricks between floors?

    The basement is being professionally renovated and will have sufficient other ventilation in accordance with Building Reg's, but want to avoid a huge cold cavity between floors, so wondering if the air bricks have to stay (as there are none between other floors)? I'd much rather my heat seep up...

    Air ventilation bricks between floors?

    Hi, I have a basement with air brick ventilation, but am about to have it excavated to add a further floor and useable rooms to my house. I’m assuming I can remove the air bricks as ventilation isn’t required between floors of useable rooms. Am I right? There are no air vents between the...

    Bricking up window in solid brick wall

    Thanks for the tips! Sounds much simpler to place the flue outlet away from the lintel.

    Bricking up window in solid brick wall

    Hi, I have a small ground floor window (860 x 1150mm) to brick up before a new combi-boiler is hung there, and have a few queries; - Would there be any issues taking out the lintel, as the boiler flue would ideally go where it currently is, or would it be better to just rethink the flue...

    Basement ceiling insulation

    OK. The basement will have windows/trickle vents, bathroom extractor, etc, so should be fine without ventilation between ceiling and floor above, but will look at insulation also. Many thanks!

    Basement ceiling insulation

    Ok. Thanks. Would the brick air vents still be required now that the space is becoming a gap between 2 useable floors?

    Hi, I'm having the basement beneath my Victorian house developed professionally (underpinning/tanking etc), but am fitting it out myself and am not sure how to proceed with insulation between the basement ceiling and lounge floor above. It currently has brick air vents (although not sure if...
