Ohhh im with you. Yeah it will be in the way lol. Im going to plaster inside. To bring the outer course level with the inner i was going to use 100mm battens and build a stud wall, effectively on top of the inner course. Screw the plasterboard to the battens and use adhesive at the bottom of the...

The mat/raft/slab foundation is likely what i will go with. How do i determine the thickness? All i can seem to find is advice like "extensions require 200mm, sheds require 100mm", nothing specific on load requirements. My build isnt an extension, but it isnt a shed either, what thickness...

What do you mean by step? The wall will be full height on the outer skin, and only 2 blocks high on the inner skin. I was going to build both skins straight onto the flat top of the foundation exactly as per my picture. Is this correct or the wrong thing to do?

Ive seen the step in many drawings but didnt realise it was for a purpose. Forgive my ignorance, but please could you tell me the purpose of the step?

wow thanks for taking the time to put so much effort into your reply. Your diagram was my exact initial concept, however we want the patio doors to open flush with the wall on the outside, so the second skin will have to be on the inside. The building will be on a raft/slab/mat foundation. Do...

What about a partial second skin? Say about a block above ground level, on the i side, with the dpm between the blocks? Ive got to sell this build to the Mrs who will be covering half the cost, so really trying to avoid the cost of a second skin.

This will be a golf simulator room. Not planning on having any insulation or heating, it gets hot enough when youre continually swinging a club lol. Does the tanking slurry option with DPM in the foundation sound feasible?

Floor level to be 30cm lower than the ground level outside. I wont be able to have any drainage. There will he a slight step up into the door and then a step down to the floor on the inside.

Im thinking a single skin block wall laid on top of a raft foundation. Around 1.5 blocks high to be below ground level. DPM to be within the foundation. Initially I was hoping to run it up the wall however being single skin i couldn't think of a way to acheive this, so i thought about tanking...

Is there an actual formula to calculate the required foundation? For example: X dead load + Y soil type + Z distance from a tree = foundation How do structural engineers calculate it? Ive seen BC poke the floor and say "thatll do", but there must be more to it than just guess work.

Haha ive read it as a slab all over google. Rafter makes me think of a roof lol. How deep do you recon id have to go to be safe?

Hi guys, Me again with another question on my latest project. I know there are other similar questions, but i havent found an answer yet. In case you havent seen my other posts, i want to build a large shed/out building in the garden within permitted dev. Please see the picture attached...

Hi guys. So I want to build a large shed at the bottom of the garden (some of you may have seen my other post). Im going to build it out of block. My only issue with it is, I need 2.5m clearance between the floor and the roof (enough room to swing a golf club basically). My neighbours garages...

Good point, i completely overlooked the non combustible material rule, this will be 60cm from the boundary in 3 directions. Looks like building it out of block is my only option. Good idea about the JJ I beams. I will take a look. Thank you

Hi Guys, Background: Im thinking about building a large shed in my back garden, outside dimensions to be 5.4m x 5.4m, with a pent roof, the highest point being 2.5m tall. I will build the shed from scratch, im thinking about using a timber frame and shiplap. Ive built sheds in the past, and...

Just to follow up on this thread for others that were in my situation and need help... So the doors were made last year, i clamped the warped/twisted wood flat to my workbench, assembled and glued the pieces together. I then routed out a 10mm slot along the top and bottom edges of the doors and...

i have a wooden frame with x4 lengths of 63x38mm sticking out vertically upright, where i need to trim the ends back by 60mm. The crux of the situation is I need to attach a piece of wood to the ends i am cutting to join all 4 uprights together, so all the cuts i make need to be square. As...

Hi guys, Put a layer of bonding coat on a wall a couple of days ago however I have since noticed a couple of low spots (around 5mm). Can I fill these with a small skim of bonding (will it dry and adhere ok without cracking or coming off? Data on the british gypsum website says it should be 11mm...

Will the silicone take to the wood and the brick? Didnt want to go expanding foam in case it leaks through the neighbours side.
