ᐅ Building a Terrace Using Formwork Blocks

Hello dear forum,

we are currently planning to build a terrace accessible from our kitchen and wanted to ask for your opinion on our idea. We want to remove the window and replace it with a balcony/terrace door. For this, the masonry under the window will need to be removed.

For the terrace, we plan to build a U-shaped frame around with formwork blocks and then fill it with concrete and reinforcing steel. The inside will be filled with construction debris and all the asphalt we want to remove from our driveway, which we will compact thoroughly. This should fill the terrace properly.

On top, we will add a layer of concrete with reinforcing steel, and then depending on the finish, either tiles or terrace slabs.

Has anyone done something similar? Did you face any problems afterwards, or were you satisfied with the result? Here is a picture for illustration.

Best regards and stay healthy

Here you go. It turned out really well. After that, just put the slabs on top, and it will be perfect.

Well, success is relative. I wouldn’t voluntarily put a huge concrete block or eyesore in my garden.
At that height, you almost definitely need railings all around; otherwise, Aunt Erna could easily fall backward after three glasses of sparkling wine at the next family gathering. A staircase would probably be a good idea too.
By the way, the opinion that this doesn’t concern the neighbors is incorrect. Depending on the situation, both the construction itself and the changes in height can be legally problematic in terms of building regulations or planning permission.
Still, if you made it yourself and you’re happy with it, congratulations.

1. A railing will be installed all around.
2. If I coordinate with the neighbor, and we both agree, PLUS the municipality legally approves the project under building regulations/planning permission, then I see no problem in constructing something like this.
3. A staircase will be added next week.
4. What’s so bad about this “block of rubbish”? We like it, and once it’s finished, it will be a beautiful terrace. It doesn’t have to be labeled as rubbish right away.

By "trash," I only meant the type of material used. The plan was to reuse the debris from the driveway.
Your terrace itself wasn’t meant in that way.
By the way, I just removed a similar massive piece at my brother-in-law’s place. The 11kg (24lb) hammer had many hours of work, and my hands, arms, and back still thank me.
As long as everything is agreed upon with the neighbors, it won’t be a problem.
If you like the terrace and everyone else involved is happy with it, congratulations from me—that’s genuinely meant. In the end, it’s just a matter of taste, no offense intended.

What has the neighbor on the other side built?

I see a potential issue with the privacy screen, as the original ground level counts. If the neighbor does not want a 2.5m (8 feet) high fence, then there won’t be one.
Even if everything is fine with the current neighbor, a potential new neighbor might see it very differently.
