ariel photos will show up shallow ruins, deeper you will need scans of some sort. Call in tony robinson!

yup, was watching time team last night - the geophysics guys walk about proding the ground with some clever sticks that check the density of the
ground and can pick up denser material ie stone and/or different material due to infill which would tell you. No idea where to comemercially get this
kind of survey/service or how much it costs?! As for aerial views - tried google earth and zoomed in?!

i was reading in new scientist about a device that could tell from a plane what the density of the ground below was, by measuring gravity - can you
imagine how hard that is?!  used to find diamonds.

Ground Penetrating Radar - outlined by Ned as used by time team
Murphy's 2 laws
1. If it can go wrong it will
2. In case of emergency - refer to rule 1.

The yellow things the water board and power services use might pick something up. I've seen them waving them about for different purposes.
yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

Depending on the soil type and moisture you can get a long way with a thin steel rod shoved into the ground - need to know roughly where the house was
obviously.
Timeteam use two types IIRC, the radar thing, and a simpler resistance measurement.

I don't think that footings gurgle much, nor do they give off much electromagnetic radiation.
I suggest a trench across where you suspect the footings may be, and carry on from there - still a Time Team approach, but a bit more practical!

Most likely pipe and leccy detector.

CAT scans prob wont pick it up,i have seen people using bent peices of stainless steel rod like water deviners.....before you all laugh,i tried it and
it worked for water
who cares who wins

Have you got a mate with a plane? will show up for sure from the air. Or start a rumour about buried treasure in the field and let some mug dig for
you

I was thinking it probably had services to it, an ordinary metal detector might show something up if there was lead pipework.

just had a price for a ground radar team to come and have a look.£1500 a day ,so i rang a m8 and he said i can borrow his mini digger,i dont think
i'll be at the controls tho,,,its not fast anough

I'm with Iank on this one. Set out a grid with string or spray paint over the site.
Get a bit of mild steel bar, about 1200mm long and 15mm dia, bend a handle into the end and poke it into the ground. Assuming the soil isn't
frozen you should be able to push it well down into the soil. When you find a point where you can't get it in too far have a bit of a dig.
It'll either be a rock or a bit of the founds.
