Obviously I worked ahead and hoped I'd get to claim that lot on the strand. I was worried about water in the basement if I placed it anywhere else. I didn't play it enough to check for water, wo I should double check that. I did include more pics in the upload because it's a huge, by my standards, house.

@Sandraelle - I did use the nraas way of upgrading with debug enabler and was able to upgrade the electronics and other stuff by clicking on them individually and using the debug enabler to upgrade to fireproof, improved etc.
