Cost for adding a 2nd floor to a bungalow

[tburfield]

Have been thinking seriously about taking this on as a project.

Finances are tight, and so I'm thinking about selling up, buying a cheap 2 bed bungalow, and then adding a 2nd floor to create a much bigger (hopefully 4 bed) place.

My reasoning for considering this:

1. Bungalows tend to have decent size footprint already, so no eating into the garden to extend.

2. Am assuming that cost of the bungalow, plus building work, would be cheaper than buying an equivalent property ready made?

3. Most bungalows are modern(1960s+) - hopefully meaning that councils won't have too many planning concerns.

4. I end up with the house being laid out as I would want.

I'm not looking to make a profit from this - just want to end up with a comfortable family home.

Is it actually worth going any further with this, or is there some glaring point that I've missed?

Does anyone have a (very) rough idea of the likely cost for the building work on a project like this? Just assuming an average 2 bed detached bungalow.

Thanks,

Tony
