Converting a conservatory to an extension

Question

I have a conservatory with dwarf walls, I am looking to make this a full extension. I understand the footings may not be deep enough, what is the best way to get them to the correct depth? I am happy to take down the dwarf walls but don't really want to disturb the  current flooring as its a finished floor and plumbing is installed so looking to keep extension same size as  current conservatory just bricking up walls, adding bi folding doors and a solid roof. Thanks

I have just finished the same conversion that your looking to have done ,unfortunately we had to demolish the conservatory and start from scratch with new foundations under instructions from building control

First of all I would do a trial dig on the footings that are in place to see what sort of depth they are for an extension your typically looking at 1mtr or more in depth otherwise you don't have no choice but to break the old footing out and dig deeper if you get a good builder they should be able to do this without damaging the floor to much

Tom · Answer

You will need to remove the footings and lay a new foundation. It will not meet building regs otherwise.

Justin · Answer

Your foundations need to be deeper depending on strata conditions adding to this the possible risk of accidental damage during construction causing issues such as burst pipes is avoidable by removing such hazards in the first place. Most likely this would disrupt the current flooring and likely need replacing. I would advise a complete design and build.
Hope this helps

You would need to dig down the side of your current foundations. I would dig two holes. Foundations should be at least least 600mm. If in doubt give your local council building control a call for advise

There is no easy solution to your problem. If the base is not strong enough to take the weight on a full wall then you must pull it out and start again. You could keep the floor and protect it with foam boards and cover that with 18mil ply sheet and work from there. The easiest thing to do first is dig exposing hole at 4 or 5 points to expose your foundation. That will tell you if its good enough to build on. I always put a 12inch deep foundation on any 1 story new extension I build. Best of luck
