Rather than magnets, my suggestion would be to use small, square strip wood to outline the base around the outside of the structure. Sort of makes a socket for the building, and looks like a footer.
You can buy Mel's size magnets by ordering at Home Depot. Free shipping to the store.
Those disc magnets from HF might be too strong.

gmpullman Hi, Mel I'm always scrounging junk and I had a few transformers that I had no use for. With a little tapping and prying I got the lacquer loose from the laminated core of the transformer and have a nice supply of rectangular and E shaped iron plates. The rectangular plates make great flat car loads. Thanks for sharing your idea, Ed

Harbor Freight - there you go! I stop by there at least once a month whether I need to or not!

I plan to use a similar idea for securing some tall PRR catenary poles along a few streches of my main line. My plan, though, is to cement a flat piece of iron to the "feet" of the poles but sink the magnets flush with the scenery base. This would give me a little wiggle room instead of trying to get perfect alignment with all four magnets..
I have used this method for securing roof sections on to buildings, again using the flat iron pieces. I'm always scrounging junk and I had a few transformers that I had no use for.

Even the white markings on the edge of the plate were from a stamp on the old transformer.
I have a place where pipes run into the side of a building. I used a magnet and plate here, too, so I can "disconnect" the pipes from the side of the building if needed.

Four tiny magnets are glued inside the pipe flanges and the iron plates are glued to the building.

Where do you get your magnets? In bulk? I may have seen a similar article several years ago- or perhaps it was an earlier post by you. This is very helpful as I have about 10 led-wired structures to locate on my layout and your system would make it easier to place and to re- place them when required. Let us know about the magnet source. Thanks !
