Hi, Firstly im not in the UK so UK Building regs dont count although might serve as a useful guide.
Im putting up a timber framed workshop on my flat roof.
Wind is my main concern.
the frame will form an L shape into a corner which is made of heavy local stone blocks.
i want to put down a row of concrete blocks as a footing on which to mount a sole plate and then the walls. i will run a line of mortar as a base and also in the block voids as I go. The walls will be attached at the ends of the two legs of the L to the existing walls as will the joists for the roof
my question is,
1. do i need to anchor the blocks to the roof floor with rebar drilled into the floor (concrete) and tied to a horizontal bar running the length?
2. use metal ties over the sole plate anchored into the floor?
3 no anchoring needed just the blocks?
4, suggestions
thanks for any advice in advance
Pete
