I have a 30ish yr old Woolaway bungalow which I believe has a ‘floating foundation’. Obviously a second storey couldn’t be built onto it like that so over the years we have extended out and up. However, I now need a bathroom built into the attic of the original bungalow. So is it possible to just strengthen a small portion of the original foundations either side of the bungalow to achieve this? You have no idea how difficult it is to get an answer to this particular question and hope you may be able to help.
