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

  • Developers who want a better, repeatable product
