    40m2 Extension Self-Build

    Wednesday morning we dug out the soakaway and the rest of the footings. We finished about 5 min. before BCO arrived and signed off the soakaway and the footings. He also offered quite a lot of useful advice (or homework, depending on how you look at it). Wednesday afternoon concrete arrived...

    40m2 Extension Self-Build

    Tuesday morning the BCO came out and confirmed he was happy for us to only dig down to 800mm. He was also happy for us to use a 450mm wide bucket instead of the 600mm bucket. Talk about good news! Digger driver basically paid for himself now, as I'm sure I would've continued to the previously...

    40m2 Extension Self-Build

    The plan is somewhat fluid, but I'm hoping to end up with something along these lines. The bits in red are the extension.

    40m2 Extension Self-Build

    Day 1 of digging today. Took out the old concrete patio (30m²) in about 2H in the morning, and started digging the footings. 80cm in we hit a lot of flint, so much so, the digger driver couldn't get through it. He advised calling the Building Inspector out for tomorrow morning and seeing if he'd...

    40m2 Extension Self-Build

    After weeks of no progress, as I couldn't find a digger driver with time (just didn't feel confident enough digging close to neighbors house), I get a phone call at 16H30 last Thursday: "Are you home, can I drop by in 10 min for a chat.". Long story short, guy finished a job earlier than...

    40m2 Extension Self-Build

    First things first. Removing the old back porch. The weather was great over the last two weeks, so this was quite fun. It helped that the roof wasn't actually fixed to anything and the bricks must've been built with a 57 to 1 mix. Honestly, the roof was just added on top and wasn't fixed to any...

    40m2 Extension Self-Build

    Time to give back a little to the community here. Have bit the bullet to extend the house myself (or as much as I can), so thought I'd share my progress here. For context, I'm 38 and work in an office. So no real building experience, apart from watching hours of YouTube videos of other people...

    Central Heating Pipes in Concrete Slab (or should I go for a screed on top of the slab?)

    Thank you. Already bought the 100mm insulation. But I like @cdbe 's method so will go for that. Slab is 11m by 3.5m so I think I might need some mesh too. More research required. Big day tomorrow. We dug footings to 800mm today and found a lot of flint in the clay. So much so, we can't get...

    Central Heating Pipes in Concrete Slab (or should I go for a screed on top of the slab?)

    Thank you @cdbe , so you didn't run those in any conduit? Did you put any mesh down on top of that?

    Central Heating Pipes in Concrete Slab (or should I go for a screed on top of the slab?)

    I was planning to dig down my oversite to 400mm below DPC level, and doing what looked like a fairly standard floor: 150mm type 1 (compacted) 50mm sharp sand (compacted) 1200 gauge DPM 100mm Celotex 1200 gauge DPM 100mm C20 Concrete I'm now trying to figure out how to feed my radiators in the...

    Partial Trench Block Vs. Trench Fill

    Starting digging our single story extension on Monday and that means ordering concrete. I need to dig down 1m deep, and to tie in with the current house I figured I'd finish concrete 1 brick below ground. Which means I'll have 3 bricks in total up to DPC (1 below ground, 2 above). But my digger...

    Insulation Confusion

    Planning to pour a concrete slab for an extension in 2 weeks time, but am a little confused with the insulation requirements. I had originally planned to go with 100mm PIR insulation in the slab, as everyone else seems to be doing that. But I noticed that certain brands offer far thinner...

    Where can I DIY and where can I DIYnot and need a Structural Engineer?

    Starting grounds works on an extension in a week, which I'm planning to build under permitted development and using a building notice. The extension will be 4m deep by 10m long, and will have a flat roof with 1 or 2 skylights. I've done the plans myself and it all seems fairly standard and...

    Pouring Foundations & Oversite Slab at the same time

    Wasn't planning on timber floors, but insulation under concrete, with a screed over the top once the central heating pipes were in.

    Pouring Foundations & Oversite Slab at the same time

    Starting a 10m by 4m single story extension in about a month, so just starting to think about foundations. I've spoken to BC and he's advised a 1.2m trench is required. I have a guy with a digger coming round to dig it all out and I'm going to ask him to reduce the oversite at the same time as...

    How Long Would You Expect it to Take to Dig Foundations

    It is. Thanks! Did consider that as I don't mind digging, but with it being 3 times what you had to do I think I would've struggled doing it for 6 days. Especially as I typically sit behind a desk all day.

    How Long Would You Expect it to Take to Dig Foundations

    Thanks. Will have another chat with him. I'm trying to save cost by splitting the work up and getting people in to do parts of the build, and doing parts myself. Even if I have to pay him for a week it'll still work out a lot cheaper than the initial quote I got from a company that would manage...

    Front garden, about 30 metres away as you have to go around the house.

    How Long Would You Expect it to Take to Dig Foundations

    Looking to get foundations dug for an extension. 1.2m deep, 18m long (in total) and 600mm wide. Soil is sand and clay. No rocks. Struggling to get a hold of people at the moment (industry seems to be booming), but have managed to get 1 guy over. I had initially expected it to be a 2 day job...

    Best Screwfix Boiler for 4 Bedroom Detached House

    The one guy came back saying I should absolutely avoid the Viessman, which surprises me as it won best boiler a couple years in a row. Is her right? Is it not a good choice?
