This golden dome is an optional dome piece to add interest to your Tempesta city. The dome sits nicely on top f the small mosling supported by pillars. It's sized for use with the small platform and can be resized if you wish to be creative. This product is not included with either of the Hoodwinked Tempesta kits, but if you have not yet bought a kit, the best way to get started is to buy either the Tempesta Easy Start Kit or the Tempesta Master builder Kit. To help you decide; if you have no experience in building in multiplatform arenas, I recommend starting with the Easy Start Kit and then moving on to the Master Kit later by buying the additional needed pieces. OR a cost effective way to do this is to buy the Master Builder's kit and add on the Tempesta Prebuilt Hidden Lagoon which in effect gives you both kits. I offer a further discount to those wishing to buy this combination or a free item from the Tempesta Furniture line. Contact me for more details.
