Contingent gift to minor and SDLT

I have an estate where the grandmother has left most of her assets divided between her four grandchildren, three of whom are minors. The gift is contingent upon them reaching 21, and they are all under this age presently.

One parent of the grandchildren and the adult grandson are trustees.

They are interested investing the money in a property and I’m unclear on the SDLT position in this circumstance. The parent trustee already owns his own property.

Any guidance would be gratefully received.
