Rocky Mountain Plan Company brings 40+ years of custom design experience to an accessible collection of house plans. From hillside lots and flat parcels to mountain communities and growing suburbs and for the view-seeker and aging-in-place planner alike, you’ll find your home with us.
The plans in our collection didn't come from a template library or a trend report. They came from something much harder to manufacture: a second-generation family business built on four decades of experience designing real homes for real people across some of the most demanding and beautiful building terrain in the country.
Our principal designer has spent over 40 years creating custom residential designs along Colorado's Front Range – more than 4,000 homes over the course of a career that's earned wide recognition for the qualities that matter most in a house plan: proportion, flow, and an almost intuitive sense of how people actually live. The resulting designs don't just look good on paper. They feel right to be in. Rooms connect the way you'd want them to. Light lands where it should. The layout makes life easier rather than more complicated.
That's the design philosophy behind every plan in the Rocky Mountain Plan Company collection, and it's what makes our plans different from what you'll find at the large aggregator sites. We're a small, Colorado-based company that brings decades of thoughtful, people-first design to an accessible format: professionally designed house plans, available nationwide, ready when you are.
Whether you're building on a dramatic hillside lot, a flat suburban parcel, a remote mountain acreage, or somewhere in between, you'll find plans in our catalog designed with genuine care – never churned out or copied. Each one reflects a real design point of view, built on the belief that a well-designed home is one of the most important investments a family can make.

Some of our most-loved plans are our smallest ones. Our 575 sf Modern Farmhouse Carriage House is one of our bestsellers for good reason – it's versatile, attractive, and genuinely buildable. Whether you're adding a rental unit, a weekend cabin, a guest cottage, or a multigenerational suite, we understand that a well-designed small home is more than just a structure. It's a rental income stream, a space for aging parents, or a home office with a door that actually closes. Our ADU collection reflects all of that.
This is where our 40+ years of design experience really shows. We've been designing for sloped lots and hillside properties for decades – plans that turn challenging topography into dramatic indoor-outdoor living, maximized views, and finished lower levels that don't feel like afterthoughts. From the steep pitches of the Rockies to the rolling grades of the Blue Ridge Mountains, these plans were built for the way hillside sites actually work.
Our catalog is rooted in the styles that thrive in mountain communities – Mountain Modern, Mountain Contemporary, Lodge Craftsman, Scandinavian Chalet, and Modern Farmhouse – but our collection reaches well beyond the peaks. Single-level plans for aging-in-place, versatile ranch designs, and family-sized homes that work beautifully across the country. Whatever you're building and wherever you're building it, the same design philosophy applies: thoughtful proportions, livable flow, and a home that fits the life you're actually planning to live.
There are a lot of places to buy house plans online. Here's why our customers choose us – and why they keep coming back.
Who We Serve
Our customers are wonderfully varied, but they all have one thing in common. They want a home that's designed with care.
You're looking to generate rental income, create a private space for a parent or in-law, or maximize your property's long-term value. Our ADU plans are designed to be attractive, functional, and buildable – the kind of structure that earns its place on your lot.
You've found the lot, or you're looking for one. Sloped, hillside, or view-oriented, whether that's in the Rockies, the Sierra Nevada, the Cascades, the Appalachians, the Ozarks, or the Coast Mountains and Canadian Rockies. You want a home that captures what the site has to offer. Our walkout and hillside plans were built for exactly this.
You're working with clients who want thoughtful, on-trend designs, or you're building in a mountain community or growing suburb. Our plans are clean, clearly detailed, and designed with the builder's process in mind. Our Elevated Builder Advantage Program was made for you.
