Reimagine the Future of Home

Your home should be more than beautiful. It should be built for health, efficiency, and resilience. As a top custom home builder in the DC metro area, August Homes leads the way in high-performance construction, redefining what it means to live in a home that truly supports you and your environment.

Every custom high-performance home we build tells a new story: one of clean, healthy air, advanced energy efficiency, and the freedom of energy independence. We integrate the latest technologies to ensure your home is as future-ready as it is stunning, whether that’s triple-pane windows and high-performance doors, or solar power with a battery backup.

Our clients across the DC metro area, including Maryland and Northern Virginia, choose August Homes because they want more than a standard new build. They want a home designed to last for generations while lowering costs and environmental impact.

If you’re ready to reimagine what home can be, we’ll build it: a residence that delivers luxury, performance, and sustainability without compromise.

What is a High-Performance Home?

A high-performance home is designed and built with advanced construction methods and technologies that maximize energy efficiency, indoor air quality, and long-term comfort. Unlike standard new builds, our homes are crafted with:

Advanced insulation and air sealing
Triple-pane windows and high-performance doors
Enhanced healthy indoor air quality systems
Smart home energy management
Solar power and battery backup integration

The result? A healthier, quieter, and more comfortable home that lowers energy use and provides peace of mind.

Net-Zero Homes

A net-zero home brings thoughtful design, high-performance construction, and renewable energy together to dramatically reduce your home’s energy demands. August Homes takes a whole-home approach—combining an efficient building envelope, high-performance HVAC, advanced windows and doors, and solar and battery-ready technology to create a home designed for exceptional efficiency, comfort, and resilience. The result is a custom home that reflects your lifestyle while helping you move toward greater energy independence.

Passive Homes

Passive home design takes high-performance building to another level. As a Certified Passive House Builder through Phius, August Homes applies rigorous building-science principles to create exceptionally well-insulated, airtight homes with carefully managed fresh-air ventilation and dramatically reduced heating and cooling demands. Beyond energy savings, the Passive House approach can deliver remarkably consistent indoor temperatures, excellent indoor air quality, quieter interiors, and year-round comfort—all without compromising thoughtful architecture or refined design.

Community Living

August Homes is bringing the principles behind our custom homes to a new kind of community living. Our vision is to create thoughtfully planned communities where beautiful architecture, high-performance construction, energy efficiency, and modern technology work together. Rather than choosing between a well-designed home and a more sustainable way of living, homeowners can have both—within neighborhoods created with the future in mind.

Our first community, Summit Grove, represents the beginning of our larger vision to build energy-independent communities throughout the DMV.
