Thoughts please

Hi I’m at building regs stage of a small timber frame , passive based house in Devon.

Draft drawing just arrived today. I think I would like the outside to be at internal FF level based on what has already been drawn , any ideas on best option based on drawing attached

Add another 60mm to the floor insulation. Make it 200mm.

What about how to raise outside to make outside at FF? And not cause any issues with damp cause

Can’t imagine what you are trying to achieve.  Are you wanting to partially hide the dolly course?

No,  what I’d like to achieve is no step down from walking from inside to the patio outside 😁

Drain at threshold and Hardcore to buildup levels.

Not really sure what you are asking.

 

But to increase insulation thickness the whole floor would increase in height including the block work under the wall. A 100mm block on its side under the 140mm, would lift the whole house 100mm. Increase insulation depth and make it a thick screed? Plenty of different ways to do it, just think it through.
