[Frequently Asked Questions]
How are your homes different from standard project homes?
Open Accordion

Most builders meet minimum standards. We go further - using high-performance building materials to deliver year-round temperature stability, a more comfortable indoor environment, and a home that breathes. This not only helps reduce energy costs, but also supports better air quality and helps prevent mould before it starts. Our homes don’t just look good - they’re built for how you want to live.

What makes a home "healthy"?
Open Accordion

It's about proper ventilation that removes stale air and moisture, carefully selected materials that don't off-gas toxins, and design that brings in natural light while maintaining comfortable temperatures. These details affect how you feel in your home – your energy levels, sleep quality, and overall wellbeing.

How do you ensure superior comfort?
Open Accordion

Through innovative design and meticulous construction. We use advanced insulation systems, pay careful attention to sealing, and consider how air moves through your home. The result? Consistent temperatures throughout your home without constantly running heaters or air conditioners.

What's involved in the design process?
Open Accordion

We start by understanding how your family likes to live – your daily routines, preferences, and priorities. Then we help you explore possibilities you might not have considered, ensuring every detail supports both comfort and lifestyle. As Douglas and Julie discovered: "The team treated the build as if it was the most important project ever."

How do you keep the building process stress-free?
Open Accordion

With your dedicated project manager handling just 5 projects at a time, you'll always know exactly what's happening. Our online portal gives you daily updates and photos, while our fixed-price guarantee means no budget surprises.

How long does it take to build a custom home?
Open Accordion

While every project is different, we provide a detailed schedule before work begins and stick to it. You'll see progress updates daily through your online portal, so you always know exactly where things stand.

What kind of warranty do you provide?
Open Accordion

Beyond our 10-year structural warranty, we provide ongoing support to ensure you're completely satisfied. We even schedule a follow-up to address any settling issues and make sure your home is performing exactly as designed.
