This new expansion to Castles of Mad King Ludwig (see "'Castles of Mad King Ludwig'") allows players to enhance existing rooms with dual room-type renovations. The renovations can be  placed on top of the existing rooms, and turn old rooms into a completely refurbished area. The expansion includes dozens of new renovated rooms, which give players two completion awards. This expansion will be compatible with all editions of Castles of Mad King Ludwig, and there will also be a Colossal version of Renovations for players who have Castles of Mad King Ludwig Colossal Collector's Edition.
