About Upwell Builders
Upwell Builders is a licensed general contractor based in Southern California, focused on high-performance ADUs and compact homes under 800 square feet. We don’t build for volume. We build with intention and combine thoughtful design, efficient construction, and proven materials to create homes that last, perform better, and require less over time.
Where It Started
The Upwell approach is the result of over a decade working across construction, permitting, real estate, and boutique hospitality. We’ve walked hundreds of buildings. We’ve studied what fails and what holds up. From Mediterranean plaster homes to desert retreats, we’ve refined a system that cuts out what doesn’t work and keeps what does.
Why We Focus on Small
Under 800 square feet on purpose.
This size range isn’t a limitation. It’s a design advantage. Smaller projects mean better coordination, faster approvals, and smarter decisions that reduce waste and long-term costs.
Faster permitting and build times
Clean coordination across trades
Better finishes without blowing the budget
Layouts that live larger than they measure
Durability that pays off year after year
What Makes Upwell Different
We’ve rethought the ADU process. Not with more tech but with better logic. Every part of our system is built for performance, not just aesthetics.
Structure and Envelope
Durable materials like plaster, tile, and fire-rated siding
Smarter air and water sealing for long-term efficiency
Clean rooflines and weatherproof details that age well
Utilities and Systems
Grouped wet walls and chases for faster installs and easier service
Fewer penetrations and smarter layout = fewer failures
Interior Design
Built-ins instead of bulky cabinetry
Natural textures and easy-to-clean finishes
Lighting plans that balance beauty and function
Outdoor Functionality
Covered entries and integrated storage
Layouts designed for privacy, shade, and livable outdoor zones
Our Promise
Upwell homes are designed to perform for the people who live in them and the people who manage them. Our system is consistent, efficient, and rooted in real-world building experience.
Who We Build For
Homeowners adding casitas, studios, or multi-gen homes
STR operators and investors looking for long-term value
Property managers who need homes that hold up to use
