Concrete slab next to garage

Hi, I'd like to get my entrance next to the garage concreted. It's currently got block pavers covering the area. I would like a nice smooth textured finish and if possible no saw cut/construction joints/cracks (refer to attached photos for reference). The floor area is approximately 14.1m^2 with a small bit extra at the top which I couldn't measure. The whole area is indoors with 2 access points (front door and from the garage side). The slab will need to slope towards the door following the same current slope of the pavers. The area has a spiral staircase and posts which will need to be poured around. I also would like a Bowmac B132 bracket cast into the concrete (exact location TBC). The area to be concreted was part of an extension that was done to the house. Unfortunately the corner has some settlement (refer to photo " --- ") due to the perimeter foundations not being cast deep enough. I don't want any settlement of the slab and have some ideas being a structural engineer of how to mitigate this, i.e: -Removing the current pavers, removing a decent layer of ground, compacting and stabilizing the founding level with cement, put down DPM and pouring a thick slab and/or with thickenings at the edges. I'm also pondering about underpinning the existing perimeter foundations to prevent any further settlement. I have multiple renovations planned at the moment so I will manage all the different trades, I suspect the concreting will be right at the end or possibly at the beginning to avoid too much dust going on new windows. As mentioned above in terms of access: The house is down a steep driveway with minimal space for big vehicles to go down. I'm a bit hesitant to have a big concrete truck going down the driveway, what other options are there (smaller truck or concrete mixing on site?) In terms of doing the work, if it will make things a bit cheaper for me, I don't mind to remove all the pavers and possibly dig out and self compact the area. Perhaps also install mesh, corner bars, dowels, etc. Regards Brian
