Installing scenery

I've a house to put in. It was made by someone and I can't get it to work.
I thought I was supposed to make a folder in the addon scenery folder and then add the BGL file to the scenery folder. I've also a mdll file which I don't know where to put.
I've checked the help files on simv and I thought I'd done everything right .
Any pointers?
Thanks
Ben
