From recreation and wine to the ultimate in security, Bacchus delivers luxury underground construction services nationwide
Since 1997, Bacchus Caves has been the underground construction company that high-end homeowners and private clients across America turn to when they want something truly extraordinary built beneath their property.
Founded by David Provost, a licensed Professional Engineer and veteran of the mining industry, Bacchus Caves brings over 27 years of hands-on underground expertise to every project.
David’s background in professional mining gives Bacchus a technical foundation that no typical construction firm can match. He understands the earth, how it moves, how it holds, and how to shape it into spaces that last for generations.
Every Bacchus project follows a single standard: structural precision meets refined luxury. We handle everything in-house from initial site selection and structural engineering to interior finishing so every detail meets the same uncompromising level of quality from the ground down.
We don’t just dig. We design, engineer, and finish spaces that people are proud to live in spaces built to last longer than the homes above them.

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 Professional 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 Professional 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.
