When the Marshall Fire claimed the Boulder home this couple had lived in for over 30 years, they were faced with one of the biggest decisions they’d ever make.

Instead of looking backward, we helped them create a forever home that would support them through the next stages of their lives.

Their new home includes:
🔹Authentic materials rooted in the Colorado landscape
🔹Maximized Flatiron views
🔹Effortless indoor-outdoor living
🔹Advanced energy-efficient building systems
🔹Aging-in-place support balanced with beauty

Thinking about adding extra space on your property?

An accessory dwelling unit (ADU) might be the perfect solution. It can be a space for older family members or adult children to live independently, a backyard cottage for long-term guests, a customized home office, or just extra space for your family to chill.

Whatever you’re imagining, the Petra Pack is ready to help you build it with a design-build process that makes your experience smooth and fun, resulting in a space built around your expectations.

Does your home need big changes, but you're not sure if a remodel or rebuild makes more sense?

You’re not alone. Sometimes the right move is working with what you already have, but other times, your house is begging for a hard reset.

In our latest blog, we break down what to consider before you choose a path: cost comparisons, timeline considerations, your house’s bones, and how you actually want your home to feel and function.
