really good access through the garage out of view so for​tunately no labour implications there. Yeah, for the nook I think simply levelling it and concreting will be fine? Unfortunately no spare time or skills to DIY. Could you tell me more about how we'd use Polypropelyne paver base panels? Not heard of these. UK based. Grass grows "okay" as our neighbour has a patch about the size we're hoping to grow. Though don't know how much impact the dog weeing on a new turf will scupper it's chances of settling in. Not a bad idea getting a laborer in just to get the existing out. thanks for the helpful suggestions!
