Making a foundation
Got a 6m by 3m conservatory. Brick on 1 side, brick/glass on front and upvc on other wall.
Want to remove the upvc wall, move out another foot. And then put a timber wall/frame up. Roof is off as we replacing it.
Need to know what to do. There looks like theres slabs there now, (not used).
The conservatory floor i believe is concrete.
Do i need to remove slabs, dig down x far and fill with concrete? Or can i build up from the slabs with something to floor level. Then make my timber wall?

I would suggest joining onto the existing footing by adding more concrete drilling into the existing footing to add Steel to help the bond from new to old
Usually it depends on the weight how strong foundation has to be. Sounds like you need your footing, foundation wall and slab to be done. Poor foundation will ruin all your work above… simple as that
The necessary sub base snd membrane will need to be extended. Youll need to dig down and come back up to level with the material and process thats been applied to the existing.
Yes I'm god builder professional builder ???????
Remove slabs and dig down
What will you be doing to fill the gap that the ft leaves between the existing brick and glass wall?
A footing is always the better option and it wouldn't need to be enormous for a timber wall.
U can build off the slabs make sure it’s double skin brickwork
and then concrete it nice and smooth and u will be absolutely fine
I would check to see how deep the foundations are for any build ,also if moving out another foot would require extra foundation ,e,g extra slap for build ti sit on
better to digging one foot low used hardcore than used damp proof membrane. And than wold be better if put down 4inch kingspan and than finish with concrete .
I would 100 percent dig footings of at least a meter. slabs are laid on hardcore MOT and cement. this will not support any structure
No
Remove slabs and dig to you reach hard ground then pour concrete as this will prevent movement and give you a solid level base to build off
No .you have to dig the floor out to 10" Deep or 250mm to lay 50mm of scalping/hardcore then 100mm Kingsland or similar insulation then 100mm of concrete or if using concrete and screed then 300mm to finish top floor level with a liquid screed or similar
Remove the existing uPVC wall and any necessary fixtures, such as electrical outlets or light switches.
Extend the foundation: You may need to excavate the area where you plan to extend the conservatory by digging down to the required depth for a foundation, 1000mm. Pour concrete into the excavated area to create the new foundation.
Build up the new wall Once the foundation is complete, you can begin to build the new timber wall/frame up to the desired height. Ensure that the wall is properly anchored to the foundation and that any openings, such as windows or doors, are properly framed and flashed to prevent leaks.
Yes basically u need to under pin foundation same depth for regulating the building beside it
It depends how deep your concrete slab is and if you add on with concrete you will drill in steel bars to connect both slabs
I advise you dig a 300mm hole and concrete to support the frame and the roof.
You would need to dig new trenches and take slabs up and then concrete new foundation. And build substructure with blocks and bricks to DPC level.
Hi, Foundation for building regs would certainly be required it would not pass off otherwise.
Your also better off doing it correctly now than having to revisit at a later date due to damp in the timber and therefore then rotting.
Any time you are planning a new construction it is always advised to create new footings, alternatively a structural engineer would be able to check this for you with a site visit.
You need to dig down to 400 if single story or 750 is double height
