ᐅ Solid block steps, durable aluminum threshold, or natural stone window sill?

We are slowly getting into the details for the terraces and the transition from the house to them.

Concrete step slabs seem to be the common cost-effective solution, if I understand correctly.
As an alternative, I’ve come across slip-resistant aluminum window sills, but I’m not sure what to think of them.

Are there any significant advantages or disadvantages?

I imagine aluminum might be easier to install and handle, especially since my window and balcony door widths are about 2 meters (6.6 feet). I don’t think concrete step slabs are usually available that wide, so I would have to join them, which I don’t find very appealing visually.

However, I’m unsure about how aluminum would heat up in direct sunlight and what that would mean for walking barefoot.

Or should I go for a natural stone window sill instead?

We have a wooden terrace built into the reveal. It looks good.

Hello

The stonemason offers blocks of granite in exactly the dimensions you specified.
The Chinese granite is inexpensive and extremely durable. It’s just very heavy.

Is the house already finished? Important: your general contractor should carefully consider this. Insulation is NOT walkable. Cold bridge-free anchors need to be installed in the facade, with the insulation applied over them. Otherwise, problems will arise.
