    Whats the advantages/disadvantages of building first floor joists into the walls, vs timber wall plates with joists hangers..... I assume hangers off a timber wall plate is simpler, but are there any downsides......

    Well if you are constructing it then my view is you should put the joists in the wall and not using hangars.

    If it's a new build, masonry hangers are standard

    If existing, then a timber wall plate bolted with M12s then joists fitted with nailed jiffy hangers

    Its a 2 storey sides extension - ground floor is a garage.

    There isn't a functional difference. Both methods, done properly, will perform exactly the same. Building in; you are stuck with 75mm coursing. The joists should be infilled and the joint between infill block and the joists should be sealed. The joist ends should also be wrapped to protect the end grain. Wall plate method; you can have the floor at any height you want, but there's additional cost of plate and hangers. You also need to check if the hangers provide lateral restraint - if not you might have to strap separately.

    Have you had these plans drawn up, and are questioning what your plan drawer has specified?

    Are you then asking him to change the specification?

    The difference is the cost of going up to the next size timber for bearings, or buying two hangers.
