After some advise peeps



Need to build a (for want of a better word) room 2.4m x 2.4m and with a ceiling height of 2.4m



all good so far but i also need to joist this and put a floor and



1.2m wall around the edge of this to create a place for peeps to stand / view from

Im ok with stud wall and the 2.4 dimensions were chosen to minimise the cutting / work involed my question is 2 parts


1) can i just lay joists over the 2.4m squared room fix and then build the floor / walls on that or would i need to use joist hangers and lower the internal ceiling down to a 2.1m height?


2) what wood and thickness of wood would be best suited to the floor ? was thinking along the lines of 10mm ply



thanks for ya time peeps

Is this a room within a room? What floor is it on?

Can you give some more information?

Assuming this is a domestic situation, people commonly use chipboard,

18mm thick if your joists are at 400mm centres and possibly 22mm thick if you go to 600mm centres. If there's a room below this room, then you might want to put 100mm insulation quilt between the joists for some sound proofing.

Yes its a room within a room on a concrete floor

Am asking the best way of putting joists onto the walls - laying them directly on top or using hangers

More a commercial situation rather than domestic - the room below will be used but sound proofing is not an issue
