17% of an existing building.
100% for Marietta.
We want to reuse part of a storage building that has stood here for about forty years, and put a small, enclosed computing facility inside it. The storage business stays. Nothing new gets built. Here is the whole plan, in plain language.
Smart Water
The loop is sealed and air-cooled. Filled once by truck from outside the county. Nothing is ever discharged to the sewer.

The community is the center
Everything we build sits inside a place that was here before we arrived. The people, the schools, the streets, the tax base — that is the center of every decision, not the frame around it.
In Marietta: this building has stood on Powers Ferry for about forty years. We're the ones who showed up recently, and we're asking to use part of it.
Technology that behaves like infrastructure
Water pipes, power lines, local roads — the technologies communities trust are the ones they can rely on and rarely have to think about. Digital infrastructure should aspire to the same.
In Marietta: enclosed, quiet, no public traffic, held to a limit measured at the property line. If we do this right, you forget it's there.
Built for the long return
Reusing what already exists — buildings, capacity, land — costs less to the planet and more to the community. That is not a marketing claim. It is the shape of every decision we make on a site.
In Marietta: no new acres, no new buildings, no added pavement. The trees stay. The storage business stays.
Why this building, in this place.
Four reasons that don't depend on trusting us, and one that does.
The zoning already says yes
Not a rezoning. CRC within a Regional Activity Center, unchanged. The corridor was designated for this long before we applied.
Here longer than the objection
A warehouse in 1988. Self-storage since the nineties. Trucks and customers all day. This is the quietest chapter the building has had.
A retrofit, not a bulldozer
Nothing cleared, nothing remediated. No new acres, no new buildings, no added pavement. Equipment goes inside what's standing.
The money stays in Marietta
Marietta Power belongs to the city. Commercial rates from a long-term customer fund city services rather than leaving town.
And because you can hold us to it. The conditions are what make a claim cost something.
A data center that answers to the neighborhood.
No city water for cooling. Revenue to the city's own utility. A sound limit at the property line.
Your concerns
improved this plan.
Here's how.
A council member said she had too many sound questions and wasn't a scientist. That question is why an independent acoustic study is now underway.
"How loud will this be at night, and who checks?"
The chillers are variable-speed, and they carry a factory control called SilentNight that holds them to a lower sound output on a time-of-day schedule. That's a setting, not a promise. An independent acoustical engineer measures at the property line, and that measurement becomes a condition of approval before we can open. Not our measurement — theirs.
"Won't the sound bounce off the I-75 wall and back at our homes?"
The highway wall between this site and I-75 is roughly 20 feet of sound-attenuating barrier, and attenuating surfaces absorb and deflect upward rather than returning sound at the angle it arrived. That is the engineering answer. The tested answer comes from the acoustic study, which now models reflection off that wall specifically — because it was asked in the room.
"We don't know what you're storing about us."
Nothing about you exists here to store. This is inference equipment: a request arrives, the hardware computes an answer in milliseconds, the answer leaves. There is no training, no profile-building, no retention. No cameras face the neighborhood. The building is a utility room, not an observer.
"An eight-foot fence isn't enough for the homes behind us."
A fence at the property line does little for sound, so we stopped treating it as the answer. The proposal now encloses the chiller yard itself in a sound-attenuating barrier — stopping noise at the source rather than at the line. The equipment already sits downhill behind a grade rise and the retained tree buffer. Wall height at the boundary remains under discussion with Council.
"Data centers drink millions of gallons. We're in a drought."
That's true of evaporative cooling, which is what large campuses use — and it's why we didn't specify it. This system is air-cooled and sealed: the loop is filled once, by truck, from a source outside the county, and then it recirculates. No cooling towers. No evaporative loss. No process discharge. The only water on our city bill is restrooms.
Promises are worth nothing. Conditions are enforceable.
A developer saying "trust us, it'll be quiet" is worth exactly what you think it is. So we asked the City to attach these to any approval as conditions.
- 01Requested as binding
Adaptive reuse of the existing building
Computing equipment stays inside the building already standing. No new construction.
- 02Requested as binding
No increase in impervious surface
The property is already developed. This project adds no pavement.
- 03Requested as binding
Generator enclosures, weekday testing only
Fully enclosed or acoustically screened, maintained in good condition, tested only during business hours on weekdays.
- 04Requested as binding
An independent acoustic study before we may open
Performed by a third-party acoustical engineer, confirming compliance at the property line. If it fails, we don't open until it passes.
- 05Requested as binding
Shielded, downward-facing exterior lighting
Full-cutoff LED with motion sensors and dimming. No spill onto neighboring properties, no sky glow.
- 06Requested as binding
Closed-loop cooling, no municipal water for cooling
Sealed, air-cooled. No cooling towers, no evaporative loss, nothing released to the sewer.
- 07Requested as binding
Construction best practices
Dust, erosion, sediment runoff, debris, staging and construction traffic, all managed to standard.
- 08Requested as binding
Equipment oriented away from homes
Mechanical equipment, generators and other noise sources placed to direct sound toward I-75.
- —Under discussion
A privacy wall along the residential boundary
New construction along the full length of the boundary. Height remains under discussion with Council.
- —Requested as binding
Perimeter trees retained
The mature buffer stays. It's the screening you already have, and it doesn't get cleared for this.
A condition isn't a courtesy.
If we violate one, the City can act against the approval itself — and we lose the thing we spent $100 million to build. That asymmetry is the point. A promise costs us nothing to make and nothing to break. This costs us everything.
It's a fair question:
what is this, exactly?
"Data center" stretches from a hundred-acre campus to a room of equipment inside an existing building. This is the second kind.
A retrofit
- Equipment installed inside a building that's stood here about forty years.
- One tenant, roughly 17% of the site. Storage keeps the rest.
- Sealed, air-cooled, contained within the building envelope.
- A small on-site staff. No public customers, no freight, no late deliveries.
- Built on power, fiber and access that are already here.
- Designed with room to add solar later.
Not the thing you're picturing
- Not a campus. No cleared land, no new buildings, no new acres.
- Not a place that keeps anything about you. No cameras. A utility room, not an observer.
- Not evaporative cooling. No towers, no daily draw on city water.
- Not a new substation. No power plant, no major transmission expansion.
- Not a rezoning. CRC within a Regional Activity Center, unchanged.
- Not publicly funded. Entirely private capital, billed at commercial rates.
The place people are describing exists. It just isn't this one.
It makes a decision, then forgets it.
Here is what a working second inside the building actually looks like. A local hospital, clinic, or city system sends a question — is this scan urgent, is this transaction fraud, is this 911 call a duplicate — the building answers in the time it takes to blink, and the question is gone. No file is saved, no profile is built, no record is kept. The building's job is to answer and forget.
Nothing is kept. The request leaves, the answer leaves, and the building goes back to waiting.
You already know this building.
The self-storage business at 1155 Powers Ferry Place is ours. It has been for years. We're not a developer who found Marietta on a map — we're the company that has been quietly running this property while the neighborhood went about its business.
- 01Family-owned, not a fund.
Prime Group Holdings is privately held and family-run. There is no outside investor to answer to and no exit date on a spreadsheet.
- 02Already in Marietta, three times over.
Sixteen storage facilities in Georgia. Three in this city. This one has operated for about forty years without a complaint worth remembering.
- 03The same company operates it after approval.
This isn't sold to a data-center operator once the zoning clears. The people responsible for the building today are responsible for it afterward.
