After our first attempt to build a snow gannet failed thanks to the wrong kind of snow arriving, we watched and waited for the next snow fall.
Sure enough, it arrived on cue, keeping the visitor centre closed but giving us time to create our work of art.
And with the help of a bale of straw, we managed to make something we think the Tate Modern would be proud to display.
If the snow stays, we'll aim for a snow kittiwake.
