The only agent who speaks fluent berm.

Architectural lighting reveals the thermal mass. Sectional diagrams included. Closed $112K above appraisal.
THERMAL ENVELOPE DIAGRAM
Every Burrow listing includes a sectional diagram showing the earth-sheltering depth, thermal mass, and passive solar orientation — the data appraisers need to price correctly.
Most agents shoot your home like a liability. We shoot it like a masterwork.
Conventional agents see a dark driveway photo and a house that "doesn't show well." They price it $60–$120K below its actual value because they don't know how to document thermal mass, passive solar gain, or embedded earth-sheltering R-values.
Burrow was built specifically for this. We speak the language of berms, retaining walls, and thermal envelopes — and we find the buyers who've been waiting for exactly what you built.
A listing strategy built for homes most agents can't describe.
Each phase of the Burrow process moves deeper into your home's value — the way a good floor plan moves you from entry to the heart of the structure.
Site Assessment & Energy Audit Staging
We visit your property with a thermal imaging camera and a structural eye. We document earth cover depth, waterproofing system, thermal mass composition, and passive solar orientation — the data that unlocks accurate appraisal.
Deliverables
Includes: Thermal imaging · Structural documentation · R-value calculation · Appraisal data package
Phase 1 of 4
Specialty Architectural Photography
We bring in photographers who understand how to capture the interplay of light through clerestory windows, the monolithic beauty of a rammed-earth wall, and the surprising spaciousness of a properly designed underground plan.
Deliverables
Includes: Architectural stills · Sectional diagrams · Thermal envelope visualization · Drone survey
Phase 2 of 4
Precision Valuation & Listing Strategy
We build a custom comparable analysis using our database of 37 closed earth-sheltered sales — comps that don't exist in the MLS. We price to the energy asset value, not the driveway photo.
Deliverables
Includes: Earth-sheltered comp analysis · Energy cost modeling · Buyer demand mapping · List price recommendation
Phase 3 of 4
Targeted Buyer Matching

Deliverables
Includes: Curated buyer outreach · Passive house network · Specialty publication placement · Off-market matching

I didn't know what I had until Burrow sent me the energy cost modeling. My parents built a $390K asset.

The sectional diagrams Burrow produced for my listing were better than my original architect's drawings.
