Joshua Tree Off-Grid Solar ADU
Set on a sprawling 10-acre parcel in the high desert of Joshua Tree, this 2023 project was an exercise in complete utility independence, transforming raw desert terrain into a fully habitable, solar-powered ADU retreat.
Off-Grid Infrastructure
- 375-foot deep water well drilled to service the full 10-acre property — completely off municipal lines.
- Full on-site septic system installed for independent waste processing.
The ADU Conversion
- 30-foot RV converted into a permanent ADU on a poured concrete foundation slab.
- Full unit and utility shed hardwired into a self-sustaining solar array.
Desert Hardscaping & Carpentry
- Wrap-around deck built into the Mojave terrain with reclaimed railroad tie staircase.
- Dedicated sunset observation deck with panoramic Joshua Tree valley views.

Initial grading and trenching for the septic system and massive 375-foot deep water well.
Deep utility trenches dug to route water and off-grid power across the robust 10-acre property footprint.
Forming and rebar grid placement for the heavy-duty concrete slab designed to support the 30-foot ADU and outbuildings.
Finished concrete foundation slab bearing the weight of the converted ADU, anchored entirely off-grid.
Custom horizontal slat privacy walls constructed to shield the fully-powered ADU from high-desert wind and visibility.
Custom staircase built natively into the hillside using reclaimed railroad ties, leading to the designated "Margarita Hangout" spot.
Steel and timber framing phase of the massive wrap-around observation deck overlooking the valley.
The final sunset observation deck spanning the rugged terrain, fully shaded and integrated into the desert landscape.
