Thanks, would concrete blocks work instead of bricks?

This is the way I've been advised to do it? Can I ask your professional opinion on this is this overkill or the best way to do it

I've been told the same but was hoping to do it as a slab in one pour as it will be quicker and easier for me to do....ive never layed bricks either.

Also I was planning on 2 course of engineering bricks around the bottom edge to raise the timber wall away from the ground a little

Insulation in the walls will be celotex or similar

Thanks Tony Please excuse the poor drawings but these were 2 of my ideas. I was told that building walls on the edge of the slab would cause the edges to crack. open to any criticism or advice ?

Hello all,happy new year I'm in process of building a 4mx3.5m garden room to house a few aquariums. Im wanting to do a concrete slab that finishes just above the surrounding land and have the concrete as the floor inside the room this will help with the 2.5m height ive got to work with. I've dug the area deep enough to allow 150mm of compacted type 1 mot......25mm sand 100mm insulation and 150mm of concrete. However ive joined a group on Facebook for home builds/offices etc and had a few people say that a slab built in this way won't be strong enough. The walls will be 2x4 then osb and cedar cladding and roof 2x6 with osb then rubber so not exactly light but far from weight of brick building. Ive been advised to do trench foundation and blocks to height of floor then concrete in the middle, is that really necessary for wooden building? Id also like to insulate underneath the slab, ive seen videos of people lining the bottom and sides of the form with insulation boards and then pouring the concrete onto this. Would this be good way to do it? As you can probably tell im no builder ?(car trade) and im quite confused as the best way to do it. If someone could help me out or point me in the right direction it would be much appreciated. Thanks ?
