Mantle (geology) The mantle is a layer inside a terrestrial planet and some other rocky planetary bodies. For a mantle to form, the planetary body must be large enough to have undergone the process of planetary differentiation by density.
Found the The HandR Average Build Cost Guide on the homebuilding.co.uk website, which is exactly what I need for estimating the cost of newbuilds. From this got a cost of ~Â£1400 per m^2. I still don't have any accurate information on demolition though apart from on average 3/5-10k per house.ound the The HandR Average Build Cost Guide on the homebuilding.co.uk website, which is exactly what I need for estimating the cost of newbuilds.

Renovation Cost / m2. Hi-I think I know what the answer will be here (it depends), but what I would like to know is, what is a ballpark figure for extensions as a price per m2. think you are looking at more like $1500m2 for ground floor extensions and $2000-2500 for second floor. That is for a basic room (like a bedroom etc) without carpets or curtains, but with things like plastering, electrical, etc etc.
