CY Turf recommendation is to keep the grass clean from debris and spray the grass twice a year with a weed killer to stop anything growing in the fibres. Grass can be brushed up if it looks flat.
Remove soil, install membrane, frame area, lay, level and compact type one stone, lay, level and compact sand base, roll out artificial grass and secure edges to timber frame. If there is a join tape and glue with artificial grass tape and glue.
Yes this is not a problem, if the grass is flat after furniture or toys being on the area can be brushed with a stiff brush. For larger playhouse etc please call.
