Just like Henry Ford's methods made better cars more affordable, our smarter building process gives you a better home, faster and at a lower cost.
Honest and transparent about costs and timeframes from day one, so you can proceed with confidence.
We take time to understand your vision, your family and the way you like to live, and share ideas from 20+ years of experience to refine what you want.
We visit your site, optimize features for your land, compare stick build, SIPs and modular options, draft your plan, and arrange soil, drainage, arborist and energy tests.
We handle approvals for you, then walk you through a complete, transparent contract. Compare us with other builders and ask anything before you sign.
Your build is split into two phases, Structure then Finishes, and only moves to phase two when you're 100% delighted with phase one.

Most building contracts are restrictive and hide short cuts inside walls and under paint. We do the opposite.
Site preparation and foundations, then the modular structure or frame, roof, doors and windows, finishing with rough electrical and plumbing.
You finalize interior doors, paint, floor coverings, fixtures, appliances and HVAC, and in a few short weeks your home is finished.
Everything is checked by our fastidious supervisor, who has never failed an inspection in 45 years.

The quickest way to find out more is a no-obligation consultation with our team, including founder and president Michael McCarthy.
This isn't a sales presentation in disguise. It's our way of sharing 20+ years of experience to answer your questions.
