Foundation Alternatives

jennypeny

Hi, I was wondering if anyone might be able to offer any build options that don't require full foundations to be dug out and cemented.

Our issue is that we have no side entrance to our garden therefore when looking at an extension the costs and time are rising due to the fact that everything needs to go right thru our house. Not to mention trying to cope with a build with three young children for however many weeks/ months it would take.

I know I have seen alternatives in the UK whereby they do quick builds that don't seem to require the same level of foundations as a traditional brick build and seem to be less costly too. I am wondering if anyone might be able to point me in the right direction ?

Thanks

You need foundations for any permanent structure in accordance with Part A of the Building Regulations.

A house without foundations? I'm a structural engineer myself...but maybe you need a magician for this one

Off site Timber frame system (SIP)
And rented accommodation.
Two things you might look into.

Steel driven mini piles then Off site construction

As above, steel driven minipiles, groundbeams, pumped concrete.

Aren't the 2 options above very similar to digging for founds, which is exactly what the OP was trying to avoid?

I'm just wondering if Mini Piles and the equipment needed to forces them into the ground can be used here, then typical strip foundations should also be a runner?

You're probably right. Though at least it's another option he could put to the builder.

Stil need to get a mini pile machine in to the area possibly crane it over the roof
It can't be that big of an extension foot print if it's a terraced house
Could be looking at crane hire to lift in mini digger and skips to dig and remove waste clay
Then concrete pump over roof for founds and floor
Or else do the one pour in a raft style foundation but that would be a decision for your structural engineer. Crane hire and pump hire ain't cheap. But cheaper than completely re doing the whole inside of your hall way and which ever room the back doors are

Piles/mini piles etc etc all need ground beams on top. If you're building structure - it needs a foundation!
