I have an existing one storey extension which I would like to build upon but the foundations are insufficient.

I would like the minimum amount of disruption to life as this extension contains kitchen etc.

The existing extension has two rooms on either end which are non essential and I was wondering whether these could be partially demolished to allow some deep corner foundations to be made. Then pillars could be used and a large joist to span the existing extension. Further joists attaching to the existing building.

The extension is ~25ft x 8ft.

Is this type of steel framing:

1) Possible
2) Economic
3) Straightforward

Any views eagerly sought.

Possible but dependant on loading and ground conditions as to whether its economical. Nothing on a building site is ever straight forward so do not go into a project like this thinking there will not be complications. There always are. The only person who can give you a difinitive answer on this is an architect on site.

Cheers for that, just sounding out whether it was worth putting the idea to an architect

architects dont size up joists, brick piers or founds, speak to an SE
