Hi
I’m looking to add a second floor extension above a previous ground floor extension but before paying for a structural engineer I want to understand what the options are regarding the existing foundations.
The ground floor extension with a pitched roof was built using the old single skin garage wall built in 1968. I’m assuming the foundations will not be deep enough for current regulations to add a 2nd floor extension.
I want to avoid knocking down the ground floor extension so wondering what the options are to support the old single skin wall so we can an extra storey.
I’m assuming underpinning is very intrusive and extensive but would it be possible to add some support steels?
Are they are other options?
Thanks
Adam
