Extensions Question

Feasibility of adding to first floor extension

I completed ground floor brick extension 5 years ago of approx dimensions 5x3.5m but now need to add first floor extension over existing works to gain another bedroom. Could you advise on following queries.
1. Can the extension utilise existing foundations.?
2. Can we protect existing flooring / kitchen units on ground floor during such a build?
I.e by building upwards above existing area

Thanks michael, belfast

Hi Michael!

Sure I can help you here:

1) In reality it all depends on the depth and width of the footings that went in to support your extension. I would assume that the footings would have been 450mm wide and poured with a Gen 3 concrete to a depth specified by your engineer ( if you had one) and/or Local Authority inspector. If you has this information I wouldn't take much to ascertain the feasibility of building off of the existing footing.

2) There are numerous ways to protect existing finishes during new works, the options are usually driven by the requirement for on going use of the protected space. In this case I assume a kitchen with daily use. This could be achieved with smart planning and construction methods. I would have to have more detail to advise you further

Hope this has helped in some way. please feel free to contact me if you need anything further
