ᐅ Installing pavers with a 2 cm gap, similar to grass joint paving?

Hello,
we would like to pave our entrance area with paving stones (or have it paved). These are not so-called lawn joint pavers. However, we would still prefer wider joints to sow a special grass mixture in the gaps and allow it to grow.

Lawn joint pavers come from the factory with built-in spacers corresponding to the joint width. Is it possible to install regular paving stones (according to the manufacturer, fill joint material of 1–3 mm (0.04–0.12 inches)) on a gravel base in a way that the stones are stable but still have uniform 2 cm (0.8 inch) joints? Are there spacers available, similar to those used for floor or wall tiles, that can be used as a guide?

This is how it should look in the end, see picture / or this is how it looks when the stones are laid "normally".

Paving stones interlock and support each other, and jointing sand further strengthens this connection. If you lay the stones loosely and walk on one, it will twist, resulting in an uneven surface with loose stones.

Yes, proper paving stones with built-in spacers are used; loose spacers placed in between can shift or eventually sink into the gravel bed over time.

Has anyone had experience with planting vegetation in the joints? Does it work as expected?
That is, only the intended plants and the sown mixture grow, without unwanted weeds (like dandelions, etc.) quickly taking over?
It shouldn’t and mustn’t become too maintenance-intensive, as it’s about 90 square meters (970 square feet), and removing all weeds twice a year would be quite a task :-(

That’s nature... In my case, you’d probably have to weed every two months – just from the work on the surrounding fields, so much “debris” ends up on the property.

You can forget about "members only" planting in the joints; usually, unplanned nature outcompetes planned nature—otherwise, the landscape would be full of hedges.
You could try setting the stones in small mortar spots, applying the mortar using a silicone syringe similar to cake decorating. Because of the processing speed, this may require preparing small batches and mixing them very fresh. Alternatively, you could create a base layer of ground reinforcement grids (paddock grids) within the sand layer under the stones. Just an idea; I haven’t actually tried this myself.

There are weed killers available for lawns. Ecologically, little happens anyway in the 2cm (1 inch) joints, and I don't understand why you would want to more or less seal 90m² (970 ft²) in this way... but then that small amount of chemicals no longer matters.

We used a special sedum mix for the joints. Everything was applied according to instructions, but it takes time… since June, we’ve been waiting for it to turn green, and only gradually is it starting to. You can clearly see what is weeds and what is sedum, and the weeds are very limited. I occasionally pull out a few weeds here and there, but contrary to our expectations, very little weed grows. In our joints, only this sedum material is present, no soil.

Oh, and around us are meadows and fields, agriculture. Unfortunately, this is also very noticeable in the garden, where unwanted plants grow. However, it’s different with the joints.
