We craft net-zero, energy-positive spaces that honor the Texas landscape. From passive solar homes to regenerative commercial buildings — your vision, built responsibly.
Every project is a response to its site — the hill country sun, the seasonal rains, the live oak groves. We design with nature, not against it.
Texas summers push AC bills past $400/month. Our passive envelope design cuts cooling loads by 60% — no sacrifice on comfort.
Austin deserves more than tract homes. We create spaces that breathe — open plans with natural cross-ventilation and light in every room.
Typical builds run 20% over budget. Our integrated design-build process locks costs early and delivers on schedule — 90% of our projects finish within 2% of estimate.
Not all "green" is equal. We use third-party verified materials and real performance data — no vague claims, just measurable results.
Austin Green Build LLC is a registered architecture and construction firm in the State of Texas (License #TACL-28471). We carry $2M general liability and professional liability insurance. All projects comply with 2024 International Energy Conservation Code and local Austin building ordinances. Past performance does not guarantee future results. Every home is unique — we provide estimates, not guarantees.
Real stories from neighbors who chose to build better — for their families and for the Hill Country.
★★★★★"Austin Green Build transformed our 1970s ranch into a net-zero dream. Our electric bill went from $380 to $42 in August. The team was on-site every day, communicating clearly. We're already planning our next project with them."
★★★★★"We interviewed five firms for our custom home in Bee Cave. Austin Green Build was the only one that brought energy modeling data upfront — not just pretty renderings. They delivered 2% under budget and three weeks early. Unheard of in this market."
★★★★★"As a real estate agent, I've seen dozens of 'green' builds. Austin Green Build's work is the real deal — third-party HERS ratings, documented material sourcing, and gorgeous design. My clients fight over their listings."
A transparent, collaborative process from first sketch to final walkthrough.
We study your land, sun paths, wind patterns, and local zoning. You share your vision, budget, and must-haves.
Our architects create 3D models with real-time energy simulations. You see projected utility costs before breaking ground.
We handle all Austin city permits and source materials from local, sustainable suppliers. Transparent pricing, no surprises.
Our crew builds with precision. We test air sealing, HVAC efficiency, and solar production before you move in.
Common questions about sustainable design, costs, and timelines in the Austin market.
Net-zero means your home produces as much energy as it consumes over a year. This is achieved through super-insulation, airtight construction, high-efficiency HVAC, and on-site solar generation. Most of our net-zero homes in Austin achieve HERS ratings between -5 and -15, meaning they produce more energy than they use. Your utility bills drop to a small connection fee — typically $12–$25 per month.
Upfront costs are typically 5–12% higher than conventional construction. However, with federal tax credits (up to 30% for solar), Austin Energy rebates, and monthly energy savings of $200–$400, most homeowners recoup the difference within 3–6 years. Over a 30-year mortgage, a net-zero home is significantly cheaper to own. We provide a detailed cost-benefit analysis before you commit.
Both. We specialize in deep energy retrofits for Austin's older homes — from 1920s bungalows in Hyde Park to 1970s ranches in Allandale. Retrofits typically include air sealing, attic insulation, duct sealing, heat pump installation, and solar panels. Many clients see 50–70% energy reduction without changing the character of their home.
New custom homes: 10–14 months from design to occupancy. Major retrofits: 4–8 weeks for energy upgrades, 3–5 months for full renovations. We provide a detailed schedule with weekly updates. Our integrated design-build approach eliminates the typical back-and-forth between separate architects and builders, saving 3–5 months compared to traditional delivery.
Every project is third-party tested. We routinely achieve LEED Platinum, Passive House (PHIUS), and DOE Zero Energy Ready Home certifications. Our team includes two Passive House certified designers and a Building Performance Institute (BPI) accredited contractor. We don't just claim green — we prove it with documented performance data.
