Concrete base for parcel box
Size will be an opinion mainly, but at least 5 to 8 cm(WxL) bigger than the box and about 8cm deep/thick.

Increase Thickness of Concrete Pad (for BBQ Island)
There's no need to raise it that much.
Put on ~1/2" of thinset, with proper slope for drainage (so, not 1/2" evenly, if it puddles now. Slope at 1/8" per foot towards the edges so water ...

The depth depends on your regional frost line. For europe we have 80-150cm (varies wildly per source, depends on your location) frost line. That means, to avoid frost-heave, the textbook says the ...

How should a 4x3 closet bend be installed in concrete?
Assuming that you are using ABS or PVC pipe and fittings, the inlet of the 4 x 3 closet bend should be flush or below the finished grade of the concrete floor. You do not want the fitting's hub to be ...

Do I need 2x6 studs in my basement energy walls?
No.
2x6 studs were used to allow R-19 or better insulation in the framed portion of the exterior walls. Unless you want that much insulation below, 2x4 walls are adequate (and standard in my northern ...

Is the box at risk of being struck by vehicles?
You might choose to have slightly more frangible anchors so they break first, minimising damage to your vehicle. Some hardwood dowells vertically with ...

Discontinuous footer?
Let's see - I guess the actual question is whether it's possible the footer is in sections, and whether that's norma/safe?
Safe - well, 20 years and the house is staying put, so probably it's safe.

How can I waterproof an exposed porch with a basement room underneath?
You build your basement room, you roof it to waterproof, you build a porch deck on top just like you build a deck on any other waterproofed low-slope roof. And yes, the roof needs to slope.

Can a concrete slab with a 6 inch deep footer support a wall made of 8"x8"x16" concrete blocks that is 8 ft high?
Depends on the soil beneath it, and how wide it is (thus, the soil loading applied to that soil beneath it.)
Typical soils have loadings ranging from 2000-5000 PSF. (pounds per square foot)

How do I finish half concrete wall in walk out basement without framing
You need insulation and vapor barrier. Drywall should rarely be attached directly to concrete. I've done it once, but it was on a basement wall under a heated garage where clearance was an issue.

Discontinuous footer?
After talking to the town building inspector, no footer is required if the foundation walls are 12" thick (which they are). This is apparently pretty common in the area.

Increase Thickness of Concrete Pad (for BBQ Island)
Since the pad has been out in the weather for a year, it won't have the best surface for keying into your new layer of concrete.
You'll need to waterblast the surface to clean off all organic material....
