Founder of Bacchus Caves
Bacchus Caves is an underground construction company based in the USA. We’ve been building luxury underground spaces since 1997. Our founder, David Provost, is a Licensed & Certified Engineer who came from the mining industry. We handle three things planning your underground site, doing the actual construction and excavation, and finishing the interior to a luxury standard. We work with clients all across the country.
Before we dig anything, we visit your property and study the ground. We check the soil, assess the structure, handle permits, and create a full layout plan. This step is important because underground construction has to be done right from the start. Our engineer reviews everything so your space is safe, legal, and built exactly where it should be.
This is where we actually build your underground space. Our team excavates the ground, builds the structure, adds waterproofing, runs utilities, and sets up ventilation. We’ve been doing this for over 27 years, so we know how the ground behaves and how to build something that holds up for decades. Everything is done by our own crew we don’t outsource the hard parts.
Once the structure is complete, we turn it into a finished space you can actually use and enjoy. That means flooring, lighting, wall finishes, climate control, custom built-ins, wine racks, home theater setups whatever your space needs. We work with your vision and make sure the final result looks and feels exactly the way you imagined it.
Most projects take somewhere between 6 and 18 months. A wine cellar or single-room underground space is usually on the shorter end. A larger project like a bunker or full underground suite takes longer. The timeline depends on your location, the soil conditions, permit approvals, and how detailed the finish work is. We walk you through all of this during the free consultation.
We build wine cellars, home theaters, safe rooms, bunkers, entertainment lounges, collector galleries, and fully custom underground living spaces. If you want a space that is private, secure, and built to a high standard that is exactly what we do. Every project is different and we design each one around the client’s specific needs.
Most construction companies have never built underground before. We have been doing it exclusively since 1997. Our founder is a Licensed & Certified Engineer with a background in mining so he understands the ground in a way most builders simply don’t. We handle the full project ourselves, from the first site visit to the final coat of paint. Over 50 completed projects across the USA speak for themselves.
Clients investing in underground construction or luxury underground construction services appreciate wine cave builder expertise, modern underground houses, and sustainable spaces. Each cave becomes an environment, not just a room.
