ADU Home Building
How we do it.
Griham Living’s homebuilding leverages the latest design and production automation tools. This ensures that the product as it is designed is fabricated exactly to those specs thereby accelerating the build cycle, eliminating rework and waste.
Architectural and structural design
We create a digital twin of the home from the architectural plan followed by a complete structural design that defines the load and the components. A full information model of your ADU is a key piece of the Homebuilding 2.0 process automation.
Sourcing and logistics
Sourcing the highest quality materials for your ADU in the US and around the globe to deliver the best bang for your ADU buck. Logistics experts coordinate delivery to our offsite fabrication center.
Fabrication automation
The designs are fed into our fabrication machines to produce structurally sound and dimensionally accurate steel components which eliminates the onsite waste associated with wood.
Onsite installation
Our flexible installation methodology allows us to install subassemblies or the entire home depending on the backyard access and topography. Our overall process compresses your timelines and reduces costs.
Steel vs wood
Prefabricating with steel factory built is more predictable and compresses build cycles. In an environment where insurance companies are raising rates or pulling out, insurance costs for steel built can be up to 40% lower as they withstand natural disasters much better.
Higher Strength to Weight Ratio
Cold Formed Steel (CFS) is lighter than wood making it easier to transport and install and reduces foundational load.
Dimension Stability
Unlike wood, steel does not warp or change with weather.
Mold and Pest Resistant
Steel does not have mold or termite problems.
Fire Resistant
Steel is fire resistant unlike wood.
ESG Compliant
Steel is over 60% recyclable and greatly reduces onsite wastage because of dimensional accuracy.
Faster Build Cycles
Steel framing and installation reduces costs by speeding up build cycles by 30%+.
Reduced Builder’s Insurance
Steel Fabrication has 40% + lower builder’s risk insurance.
Lower Property Insurance
Property Insurance in hazard prone zones like Florida can be 40% less.
Higher Strength to Weight Ratio
The framing with steel is significantly faster and does not require highly skilled labor like wood.
Where Homebuilding 2.0 will help
Supply - Demand Imbalance
- Housebuilding has lagged demand
- 3-4 Million homes under built
Poor Affordability
- Low down payment savings
- High interest rates
- High student debt
ESG Challenges
- Material waste
- 40% of global energy use
- 33% of greenhouse gas emission
Old Construction Methods
- Long completion time
- Rising labor and material prices
- Local labor shortages
The factory built advantage
Homes that are prefabricated in the factory have many advantages over on-site, stick built homes, including 50% faster build cycles as the processes are automated and more efficient while the labor pool is predictable and stable. The US lags the world in Factory-Built Homes producing only 3% of global housing stock while Finland/Norway/Sweden produce 25% and Japan produces 15% per a recent McKinsey study.
Shorter Build Times
Factory Steel prefab reduces build times by 30%+
Local Trade/Labor Savings
Factory prefab reduces on site labor requirements
Not Subject to Local Weather
No impact of weather while in factory production
Lower Builder’s Insurance Costs
Builder’s insurance is lower with steel prefab
Lower Property Insurance Costs
30%-40% savings on property insurance with steel
ESG Compliance
Griham ADU can comply with net zero energy ready requirements
