I take it by that video Lara is either moving from croft manor or redesigning it, I get the point that 60 Minute make over isn’t the best thing for that house/manor just like HighDef isn’t the best thing for `60 Minute Makeover` but wouldn’t a tin of paint be better than C4?

and in fact while I think about it Lara being the tomb raider preserver of history and such, how can she justify destroying her home which must have history and such, unless CD are setting up tomb raider 2096 now in where Lara`s great granddaughter searches for the ruins of Croft manor?

Also; not Core's mansion. That version of the mansion (based on the one in the movies) first appeared in-game in Tomb Raider: Legend, the first game by Crystal Dynamics.

I seriously doubt that the traditional mansion training level is going away. I think the events of that teaser will occur about two thirds of the way through the story of Underworld, just before Lara heads off to finish the story.

By the next game, it'll be rebuilt or re-furnished or she'll have bought another ancient pile to do up.

However, this is beyond the point. This teaser tells us nothing about the game, shows no in-game footage and has precious little Lara in it.

Pretty but not ideal for this point in the marketing campaign - we've already seen in-game footage, please put some in the trailer.
