They are lovely resin casts by Gripping Beast, sold as Large and Medium sized Wattle and Daub Buildings, but the cute elevated storage building seems to be no longer available. All painted up in multiple washes and dry-brushes in various acrylics.
Together in a block these three buildings occupy the table area of two imperial terrain blocks (noting they are measured in anachronistic, non-metric units!), so I suggest 40 points for the lot. Figures for scale only, not for scoring.
