Attaching deck posts to foundation concrete

Hi all,



First post and hope you don't mind another about deck foundations :)



I'm installing a small (7.2' x 4.2') deck and steps to provide access from our kitchen to garden which will be just under 2' off the ground.



My plan is to sit the deck frame on six 4x4's. I'm going to set the 3 outer posts in postcrete but I'm unsure of the best approach for the 3 closest to the house, which I had planned to mount in three MetPost brackets, secured with anchor bolts.



I'd wanted to keep the deck floating and avoid a ledger/drilling holes through new render and possibly affecting the DPC.



Having removed the previous old concrete/brick steps that were in disrepair, there is a mix of crumbling concrete with hardcore/sand underneath. Removing this reveals what appears to be foundation concrete (our UK house's kitchen having been extended in the 1950s with solid concrete foundations.





Is installing metposts/anchor bolts into the foundation next to the house OK?



Does it matter that the 3 posts are fixed to foundation and 3 more free-floating in the ground beyond (would that cause stress to the deck frame?)



Thanks for any advice you may have, even if it is "get a builder in!" :help:
