In Ancient Rome vaulted buildings were irreplaceable and were held in high regard, this was also where cross-vault construction was invented. Even when time has not been kind to the buildings, the vaulted cellars still firmly stand in all their glory. But the construction of vaulted buildings has become increasingly rare these days, as there’s a lack of craftsmen with the necessary knowledge. Our mission is to revive and continue this distinguished and resilient tradition. Revonia is an Estonian company established in 2010. Our main line of activity is manufacturing precast wine/earth cellars, saunas, underground grills, kitchen rooms, and wellness centers with vaulted ceilings. Cellar building tradition has been in Estonia for centuries and vaulted buildings have been constructed for almost ten centuries. We are keeping all the traditional and dignified looks of the older cellars and combining them with a modern twist and technology. Our way makes the building process less time-consuming and our cellars are stronger than ever. Our cellars are pre-made in our Estonian factory. They include handmade shelves, hinges, handles, doors, and other decorations. Styles vary from medieval to modern and even classy ones. Our solution makes exporting the whole packet easy and allows the building to be constructed on-site even with only one day!
