To bring it up to 28mm, I added 1/2" of sheet rockwork to the bottom of the church all around. In a marvelous example of serendipity, I had a Plastruct rectangular tube that exactly matched the width of the columns cast on the church. I only had to cut them to height and depth with a razor saw. I did a little filling with Squadron Green Stuff. and then painted it. The roof was thatched with funny fur (a.k.a. teddy bear fur). The cross is a jewelry piece painted to look like weathered wood.
Here are some photos after I based it. The thatch is a bit darker than it photographed. The figure is a Wargames Factory Saxon for scale.
