ᐅ Terrace Planning for an End-Row House with a Large Garden – What to Consider?

Hello everyone,

we are now moving on to the outdoor area. We have an end-terrace house with a relatively large garden but a small budget. Still, we want to build a large, beautiful terrace.

We have contacted various craftsmen, gardeners, and companies with offers ranging from $5,000 to $25,000 (or equivalent), so all kinds of quotes.

I need some ideas now:

Below is the sketch: The main point is that I definitely want two terraces: one main terrace along the house in the front, 28m² (301 sq ft), and a smaller one on the side, 12m² (129 sq ft). Now I want to connect the terraces, and I have heard different opinions on this. Some recommend offsetting the terrace stones as a pathway, etc. I have actually decided to close off the corner, meaning to expand the main terrace on the side, creating a corner terrace. Sometimes I worry that it might not look good and I’m unsure. We have a large family; I want large tables with chairs, swings, and more solid surface, but without overdoing it. Also, I don’t want to have to take care of a huge garden, so that would be practical for me. The neighbor was not allowed to build wider or bigger due to property division rules limiting the sealed area, but for Jens, that should not be a problem.

Now my question to you:
How would you plan the terrace? The bigger it is, the more expensive it will be.
What kind of slabs do you have, what material and installation method? I have quotes for 2cm (3/4 inch) slabs set in concrete or 4cm (1 1/2 inch) slabs on a gravel/sand base. I want large slabs.
I would like light-colored slabs with anthracite edging. Regarding roofing, I’m not sure if I’m allowed to build 7m (23 ft) wide and whether I can exceed the building limit line. I would like about 7 by 4m (23 by 13 ft)... but that would be 1m (3 ft) over the building limit. On the side, I have already enlarged the living space with a bay window under a special permit; I don’t know if I can add a roof there too. Now I need advice, ideas, tips—I’m a bit lost about what to consider, etc.

I’m also happy to hear about your experiences with terraces, what mistakes you made, what worked well, what you would do differently. Especially, what did your terraces cost.

Thank you

He says everything is solid and waterproof, and the slope would be sufficient.

Just for common sense: do you really seriously think that a significant amount of water passes through the joints of pitched or large slabs? Without real landscaping knowledge, I would estimate around 0.1%.
I still prefer single-grain gravel because then no moisture comes up from below. Not because of infiltration.

So some moisture would definitely seep through, even if only a little... at least that’s what is recommended in all forums and everywhere. What kind of moisture is supposed to come up from underneath? Einkorn would be cement gravel? The problem is also all the different terms; I keep getting confused.

I just looked it up, and yes, einkorn is a drainage mortar, which I would also prefer because of all the points mentioned here in the forum and in general. I don’t understand why the contractors always want something different.

2/5 split with trass compound. Is cement a single-component mortar? My husband says he wants to use that; I wanted to ask here again.

No, it is not single-grain mortar. It is drain concrete with small aggregate – but it’s something you can also use.

Why do it yourself like this?

P.S. Why use trass? Are you worried about efflorescence on natural stone? Otherwise, it doesn’t harm, but it costs more and has no benefit for porcelain tiles.
