Hi everyone!
As it’s starting to get warmer, some exterior work will probably need to be done soon! Before I dive into it, I’d like to hear a few opinions from you.
Here’s what needs to be done:
1) Installing curbstones
2) Spreading and compacting lean concrete (sometimes called flowable fill)
3) Paving the terrace and parking areas
4) Building a retaining wall
5) Garden shed
The priority is to pave the surfaces first to keep dirt away from the house.
For that, I should first install the curbstones and then fill with lean concrete.
Can lean concrete be left as is after compacting, or does it need to be leveled immediately with gravel and then paved?
(We already roughly backfilled and compacted during the groundwork, but it’s quite uneven now.)
Should the drainage channels be installed first and then compacted around? We definitely need one at the parking space facing the street. What about the terrace? At the house, along the wall, or both?
I have a wastewater connection at the heat pump, but that would require quite a lot of digging and curved piping now. Would it be an option to connect directly to the existing house connections instead? (Basically just cutting a piece out and installing a Y-connector.)
Thanks in advance for your input

I meant this channel with a grate. But they are deeper than the paving, and you have to lay the drainpipe beforehand. hm...
without being a landscaper...
the gravel needs to be compacted in layers anyway. The small plates can only handle about 10-20cm (4-8 inches). (Costs around 320€, so it's worth buying, except maybe for the driveway where you might want to rent something in the 200kg (440 lbs) class for a day because of the car)
I would compact gravel, then lay the drain pipe in the second gravel layer, then cover it with a third gravel layer. And what about the recess for the channel? Then bed the channel in fine gravel and backfill the sides with fine gravel?
I built my paths with decorative gravel and gravel grids. It looks good and was done pretty quickly.

I would always use a rainwater catch basin for drainage. It’s easier to maintain and inspect. Why?
Only for the "open" drains, right?
The patio roof already has integrated leaf traps.

Depending on the ground conditions (my advice applies to well-draining soil), I would always direct the water to the soakaway using perforated corrugated pipe. You can already buy ones with a protective wrap on Amazon (not the coconut fiber type). I would also lead the patio roof drainage into a catch basin.
Which "corrugated pipe" do you mean exactly?
The yellow perforated pipe with the white filter sleeve around it?
And then connect one or two ACO Self soakaway cubes to the soakaway pit?

I would also run the patio cover drainage into a sump chamber.
Which "corrugated pipe" are you referring to?
The yellow pipe with holes? And the white filter sleeve around it?
And then connect one or two ACO self-draining cubes to the soakaway chamber... I have sump boxes, and I put a nylon stocking in the strainer. Every 4 weeks, there’s so much stuff—from twigs and leaves to some unidentifiable slime—that it stops draining completely. And I have two full floors, with no tree taller than my house within 500m (about 550 yards).
Since my infiltration system (sandy soil) mainly consists of 15m (50 feet) of yellow, perforated corrugated pipe with a white fabric sleeve on each side of the roof, I don’t want to imagine how quickly that would clog.
If you just bury a few meters of concrete soakaway rings as infiltration and excavate them annually, then you don’t even need a sump box.
By the way, my corrugated pipes end in a depression, which I call a dry pond, and it will be suitably planted and decorated. In the worst case, water should collect there. But that has never happened. Cheers to the sandy soil here!
