The Initial Stages of Building an Extension: From Groundworks to Concrete Foundations
Embarking on a home extension project is an exhilarating journey that transforms your living space and your lifestyle. Adding more room to your house might sound simple, but the groundwork leading up to the moment the concrete foundations are poured is intricate and requires meticulous planning. In this deep dive, we'll take you through the initial stages of building an extension, emphasising the importance of groundwork and pouring concrete foundations.
1. The Vision and Design Phase:
Before a single shovel hits the ground, it's crucial to have a clear vision for your extension. This involves careful considerations regarding the purpose of the space, the design aesthetics, and how it would integrate with the existing structure. Engaging an architect or designer at this stage can be invaluable, as they can provide expertise and innovative solutions to make the most of your space.
2. Site Survey and Assessment:
This step involves thoroughly examining your property to identify potential issues affecting the extension. A site survey determines the type, size, and depth of foundations required, factoring in soil type, nearby trees, and the water table level. This process often identifies possible challenges early on, ensuring no unexpected setbacks during construction.
3. Securing Permits and Permissions:
Depending on where you live, constructing a home extension might require planning permissions or building permits. Applying for these early is imperative, ensuring that all design aspects comply with local regulations. This can sometimes be a lengthy process, but ensuring that your extension is legal and safe is essential.
4. Groundwork and Site Preparation:
With permissions in place and a plan in hand, the actual construction work begins. Groundwork is essentially the process of preparing the site for the new extension. This includes clearing the site of any debris or vegetation, setting out the exact boundaries of the extension, and excavating the area where the foundations will be laid.
One crucial aspect of the groundwork phase is ensuring that the site is appropriately drained. Water accumulation can compromise the stability and longevity of your extension, so it's paramount to establish efficient drainage systems at this stage.
5. Laying the Foundations:
Foundations are the bedrock of any extension. They bear the weight of the new structure, ensuring its stability and durability. The type of foundation required depends on several factors determined during the site assessment. Common types include strip foundations, trench fill foundations, and raft foundations.
Once the trenches are excavated to the required depth (taking into account the frost line, soil type, and the load-bearing capacity of the ground), steel reinforcements might be placed in, especially for larger extensions or in areas with softer soil. These reinforcements add an extra layer of strength and stability to the concrete foundation.
The final step in this stage is pouring the concrete. It's vital to ensure that the mix is right, considering the specific requirements of your site. The concrete is then poured into the trenches, levelled, and allowed to cure. Curing is critical; it ensures the concrete reaches its desired strength and durability.
In conclusion, while a home extension might revolve around the aesthetic and functional benefits, the initial stages are grounded in rigorous planning, assessments, and meticulous groundwork. Laying a robust foundation - literally and figuratively - ensures that your extension stands the test of time, offering you a space that enhances your home and life.

relieved to see it tamped length ways with a long straight edge after it was lasered in, great job, bricky will be happy!
This looks like it's going to be a great series and there's no stopping that girl Jen, she just loves it. 👏👏

These lot look like perfectionists. My people! I swore id never do another DIY extension, but....
Good to see 'Paddy's Motorbike' getting in on the Action 👍🤠
This is so nice to see. Looking forward to watching the extension progress. We want a 6ft x 10ft single storey extension out the back but so worried about how much it would cost. It's knowing who to trust too
Nice job Sam. One thing that always gives me the wobbles though is seeing rebar stakes without safety caps, I know it's unlikely but if someone falls on one of them it could kill them. It has happened. That old concrete looked like hard work, we always get a digger with a pecker attachment now for that reason, it's money well spent if you have old paths or bases to take up.
Motorbike boots….genius!
The laser receiver on the tamper is a great idea, equally you could use the markings if you use a laser without receiver.
Great stuff . That first bit of concrete out the chute wasn’t flowing was it 😬. Always a relief to eat the concrete In . Bring on the shite bricks 🤢🧱👍🏼
Brilliant!
0:24 motorcycle boots?! That's a great way to ruin them! 😂
Doing that pour is so stressful. The concrete bloke doesn't want to hang around but you've got to get it 100% correct. Think you've done OK. Great video - thanks.
cracking vid guys
I've never had a volumetric turn up on time, 6 hours late is my record, 5pm in december & planned to be power floated ,😄 & when they do turn up it usually breaks down.
Nice start to the job Sam. 🙌🏻. 😉

can you please talk through the various stages of planning that you would need to go through before you start things like the build over agreement etc i had to jump through so many hoops for mine it took the best part of 6 months and thousands of ££££ thanks
I have never saw opensided bucket on digger before. Is it better for wet soil?
You did a video about ladder safety a while ago and recommended Hunter ladders, the company no longer seems to be in existence, can you recommend a ladder with similar safety features? Thanks
I assumed I would have to do a metre deep footings on my extension, I was dreading the building inspector coming round because my builder only went to the existing 6" depth. I had severe doubts, however the building inspector said it was fine. We have very rocky/ stoney ground.

I definitely wish I had “rocky/stoney” ground in my garden where I’ll be pouring footings for a shed! (Short single skin brick wall with timber frame sitting on top). There’s a big Hawthorne tree that will be 1 metre away from the footing. The recommended digging depth is like 2.5 meter, but I doubt the existing (1 metre high) brick wall at the back of the garden that’s about 1 foot away from the tree and looks unaffected has 2.5 m deep foundations… so I will go a metre, maybe a little more.

I love how your videos always seem to echo what my future plans are! 😆 My proposed extension is around the back of the house with no heavy access - does it cost much more to have the concrete delivered to the point of excavation with a pump? Its not massive, just an 8x4 orangery, but it looks a lot to barrow it around!

Pumping concrete is around £400 but you can sometimes find a truck with a built in pump which means just one guy and one vehicle so it is a bit cheaper. I would say it is worth it.
