Your home. Your place.
Residents own their manufactured homes. A private backyard, independent comfort systems, and outside equipment access keep everyday life central.

Tomorrow, right next door.Interactive concept model
Setting the stage for tomorrow…
A home that still feels like home.
The residence stands on its own foundation, beside a structurally detached garage. Solar covers the usable roofs, targeting at least 20 kWdc combined. A private backyard and independent household comfort are part of the concept.
Concept model. Not to scale or for construction. Structure, acoustics, utilities, and operating costs await validation.
Now, that’s thinking ahead.
Everyday living.
Extraordinary neighbors.
You own the home. The lot brings a new set of possibilities.
HearthGrid proposes one full AI rack in an enclosed room beneath a detached garage. On a suitable slope, cars arrive at upper grade and technicians enter from a lower service lane—without walking through the home.
The proposed model combines homeowner ownership with a buyback option through the park administrator. Buyback pricing, eligibility, timing, funding, and contractual terms remain to be developed.
A pilot must prove how the housing, computing, and energy infrastructure work together. Home ownership does not imply ownership of the computing equipment or any promised computing income.
Give heat another job.
Recover a useful portion for home heating and water preheating through a separate loop. Reject the rest outdoors.
Put the roofs to work.
Solar on the home and garage contributes an electricity offset. The computing equipment still needs substantial grid power.

Go ahead. Turn the dials.
These are planning assumptions, and you can change every one of them.
Solar contributes. The grid does the heavy lifting.
Start with a national benchmark or select a state. The concept targets at least 20 kWdc across the usable house and garage roofs. The 142 kW rack average and 15% outside-equipment allowance remain planning assumptions.
Where the assumptions come from
NVIDIA lists up to 142 kW for the proposed GB300 NVL72 rack. Here it is an editable, high-load annual average scenario—not a measured average or a service rating. The 15% external allowance is unverified. The initial 12 + 8 kWdc roof capacities total the 20 kWdc design target; final roof area, setbacks, shading, structure, and module layout determine achievable capacity.
State electricity benchmarks use 2025 EIA industrial average retail prices, the same source and sector used by ThirstyGrid. They are blended prices, not energy-only tariffs, so the calculator does not add separate demand or fixed charges in benchmark mode. Solar yields are derived from NREL’s 2016 modeled rooftop technical-potential study, not current measured output. The national solar benchmark covers the contiguous states and DC; Alaska and Hawaii require a manual yield. Generation assigned here cannot also be credited to the household.

More than a clever housePlan the neighborhood.
Plan the neighborhood.
Connect the possibilities.
Repeat the layout. Plan the infrastructure together.
Power, fiber, cooling, service access, and potential heat users need a community-wide plan. Fifty homes in the starting scenario mean 50 racks and 8.165 MW of modeled facility demand, before household electricity and other site loads.
That is a major infrastructure undertaking. The compute business must support it; solar and useful heat are supporting benefits.

Quiet living is a requirement to demonstrate. So are safe construction, dependable cooling, and a workable business.
Find the right ground.
Confirm a site, utility pathway, equipment supplier, independent foundations, equipment access, and an approval route.
Build an unoccupied prototype.
Test the garage, pod, cooling, drainage, waterproofing, vehicle-fume separation, and fire protection before people move in.
Listen. Measure. Learn.
Measure bedroom and neighbor noise, vibration, power, useful recovered heat, seasonal cooling, and maintenance access.
Make it ready for real life.
Proceed only after comfort and operating requirements are met. Price the verified design and establish compute demand before repeating it.
Acoustic performance pending prototype measurement.
A detached structure can reduce direct transmission paths; it does not prove quiet operation. The rack, pumps, outdoor cooling, ground, and utility connections all need acoustic engineering.
Open the original concept drawing and design notes
The proposed 12-inch concrete deck is an unverified placeholder. An engineer must establish spans, reinforcement, supports, vehicle loads, waterproofing, drainage, and required separation. Thickness alone establishes neither a fire rating nor acoustic performance.
The concept needs independent air systems and a complete equipment replacement route. Drinking water stays isolated from facility and server coolant. The home retains independent comfort systems, and full outdoor heat rejection remains available.
An open carport above the pod is another variant. On flatter sites, an enclosure behind or beside the garage could preserve parking without forcing excavation merely to match the drawing.

Glad you asked.A few things
A few things
worth knowing.
Who owns the home?
The homeowner owns the manufactured home. HearthGrid proposes a new type of lot with coordinated computing and energy infrastructure. Lot tenure, fees, infrastructure responsibilities, and operating arrangements remain to be defined.
How would the buyback option work?
The proposed model includes a buyback option through the park administrator. Pricing, eligibility, timing, funding, and contractual terms have not been established. This website does not offer a guaranteed resale price or a binding purchase commitment.
Does the solar power the whole rack?
No. Even at the 20 kWdc combined-roof design target, solar supplies a modest annual share of the modeled facility demand. Select a state in the calculator to explore the benchmark. Substantial grid service is still required, including at night.
Does my home depend on the computers for heat?
The concept requires independent heating, cooling, and hot water. Recovered heat is an additional source when equipment is running and temperatures are suitable.
Can one home use all that heat?
We do not assume so. Useful recovery depends on actual demand and temperatures. Other nearby heat users might help, but the equipment needs full cooling even when no heat is useful.
Will it be quiet?
That must be proven. Separation, acoustic construction, vibration isolation, and outdoor-equipment placement are design tasks. No bedroom or neighbor sound level has been validated.
Is this ready to build or buy?
No. HearthGrid is a development concept seeking pilot collaborators. Site selection, engineering, approvals, costs, operating arrangements, and commercial demand remain open.
Is HearthGrid affiliated with NVIDIA?
No partnership or endorsement is represented. NVIDIA GB300 NVL72 identifies the proposed computing platform. Equipment selection and supported configuration require supplier confirmation.
