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...

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...

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...

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...

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...

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...

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...

Hi, Contractors are completing my basement and tanking it all (Delta Membrane). 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...

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...

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...

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...
