Custom Home Builders Markham for a Brighter Future
The Ontario Building Code is moving toward a clear goal. By 2032, all new homes must be Net Zero Ready. That means lower energy use, better air quality, and smart construction. It’s a shift in how homes are built, and we’ve already embraced it.
In Markham, our homes are designed to align with this future. We build with better insulation, airtight construction, and efficient heating and cooling systems like air source heat pumps and ERV units. The result is a home that uses less energy and offers a more comfortable living experience throughout the year. Avvio Fine Homes stands out as a custom home builder Markham families can rely on for future-focused construction.


Design Build Company Markham
Our Markham design build delivery method gives you one clear path from start to finish. We guide you through the design process, help develop a wishlist, and provide expert recommendations based on your lot and goals. This includes architectural drawings, proper space planning, permits, and construction.
Every home is shaped with care. We focus on energy performance, layout, and durability, making sure your new build or renovation meets your expectations from the inside out.
Sustainable Builders Markham
Our homes are built with performance and sustainability in mind. We use proven methods to improve comfort, lower energy use, and support better indoor living.
Here’s what we offer in Markham:

Custom Homes
Every custom home in Markham starts with a conversation. We design and build homes that reflect your lifestyle, values, and daily routine. Each project includes detailed planning, full permit coordination, and energy modeling to ensure long-term comfort and performance.

High Performance Homes
Our high-performance homes exceed standard building code requirements. We use continuous insulation, airtight construction tested to less than 1.5 ACH (Air Changes per Hour), and ERV systems to regulate air flow and reduce energy waste. These features help lower heating and cooling bills by up to 40%.

Net Zero Homes
Our Net Zero homes in Markham are built to balance energy use and energy production. We prepare homes for solar energy integration and use air source heat pumps, triple-pane windows, and advanced thermal barriers. Homeowners enjoy year-round comfort with energy bills that average near zero annually.

Energy Star Certified Homes
Energy Star certified homes must use at least 20% less energy than homes built to standard code. We meet this by incorporating high-efficiency HVAC systems, high-performance windows, and detailed air sealing practices. Each home is third-party tested and verified to deliver energy savings and improved air quality.

Home Renovations
Older homes often lack the insulation, ventilation, and layout efficiency of newer builds. We modernize homes with new building envelopes, upgraded mechanical systems, and improved layouts that increase energy performance and everyday usability—while maintaining the character of the original space.

Home Additions
When you need more room, our additions are designed to blend seamlessly with your existing home. Whether it’s a new second storey, kitchen expansion, or additional living space, we ensure that all new construction meets the same energy and comfort standards as the original home.
