    2nd Storey Extension only 6th Aug 18 at 12:24 PM
    Currently purchasing a property that has an existing ground floor extension (converted Garage).
    We would like to add a 2nd storey extension. Its 8.5 x 3.5 metre so fairly big. Would like the roof pitched to (I imagine this will amount to most of the cost) Looking at 2 bedrooms with en-suite to one of them. We're in south London so I know cost will be more at the top end. Original ground floor plans confirm that it will support a second storey. Just wondering if 1300-1600 per square metre is about right? Ideally want the whole project to come in at sub 50k Cheers

    Apart from a note on a ground floor plan, what other checks on this have you done? Do the foundation design calculations from the structural engineer confirm that they have been designed to take an additional storey, and assuming what construction type?

    It would be rare for an existing garage to be designed to take an additional storey. Expensive assumption to make if the required foundation and ground floor works haven't been undertaken as assumed.

    Sorry to clarify, the garage was demolished and footings foundations done so rebuilt completely.
