Custom Home Builder in Durango CO: Luxury Design & High Performance
Positive Design Build brings integrated design-build service to Durango and La Plata County — high-performance mountain homes engineered for your lot, your climate, and your vision.
Durango's Leader in High-Performance & Passive House Design
Durango sits at 6,500 feet in the Animas Valley, where January lows hit single digits and heating costs can eat through a household budget. Most builders here construct homes that meet code — the bare minimum. We build homes that exceed it by a wide margin, using passive house design principles and Zero Energy Ready Home standards that cut heating demand by up to 90%.
Zero Energy Ready Homes
We build to DOE Zero Energy Ready Home standards — superinsulated envelopes, airtight construction, and mechanical ventilation with heat recovery. For Durango's climate, this means your home stays warm through the coldest stretches without astronomical utility bills. Every ZERH we build is solar-ready, so adding panels later is straightforward and cost-effective.
Advanced Air Sealing & Insulation
La Plata County winters demand more than standard fiberglass batts. We use continuous exterior insulation, spray foam at critical junctions, and meticulous air sealing to eliminate the thermal bridges and drafts that plague conventional construction. The result is a home that holds heat where it belongs — inside — even when the Animas Valley drops below zero.
Modern Mountain Aesthetics
High performance doesn't mean sacrificing design. Our modern home builds in Durango Colorado blend clean contemporary lines with materials that belong in the mountains — natural stone, weathered steel, and heavy timber. Large window walls frame the La Plata peaks while triple-pane glazing keeps energy performance tight. The look is distinctly Durango, not suburban.
As energy efficient home builders in Durango, we've watched the building science evolve over eight years of construction in Southwest Colorado. The techniques that seemed cutting-edge when we started — continuous insulation, ERV systems, advanced framing — are now our standard practice. Every custom home we deliver in La Plata County meets or exceeds passive house design thresholds for airtightness and insulation value. That's not a marketing claim — it's verified by blower door testing on every project.
Luxury Design-Build Contractors for Durango Estates
Building a luxury home in Durango isn't the same as building one in Denver or the Front Range. The terrain is steeper, the weather is harsher, and the sites demand respect. When you're investing in a Durango estate — whether it's your primary residence or a mountain retreat — you need design build contractors who understand what La Plata County actually throws at a structure.
Our architectural design process starts with your land, not a floor plan from a catalog. We study the topography, the solar exposure, the prevailing winds, and the views that make your specific La Plata County property worth building on. From there, we design a home that responds to all of it — orienting living spaces toward the Animas Valley panorama while shielding the entry from north winds and snow drifting.
For out-of-state homeowners building second homes in Durango, our white-glove project management means you don't need to relocate to manage your build. We handle every detail on the ground — from county inspections to material deliveries — with regular photo updates and video walkthroughs so you're always informed. Explore how our process works for Pagosa Springs and Bayfield projects as well.
Custom Architectural Design
Every home is designed specifically for its lot — site orientation, view corridors, and terrain integration tailored to La Plata County's scenic landscape.
White-Glove Project Management
Real-time digital updates, scheduled video walkthroughs, and dedicated project coordination for second-home owners building from out of state.
Sloped Lot Specialists
Walk-out basements, tiered foundations, and custom drainage engineering for Durango's hillside properties and complex Animas Valley terrain.

What Our Customers Say
"Louis Garday, Sr Pagosa Springs, CO 81147 Re: Positive Design - Mark Positiviata December 23, 2025 What I immediately learned when we first started renovating my 4,000 sf log home was that above and beyond everything else, MARK IS A CRAFTSMAN AND PROFESSIONAL in the truest meaning of those words. His work for the planned 10 months was all completed in several diverse areas, on time, on budget, adding a professional flair whenever possible, such that I can easily claim that his skill and craftsman like work on every aspect of the engagement, including concrete and tile work, fine detailed carpentry, building a new 30’ by 20’ TREX deck, electrical work, safety grab bars and plumbing, repairs of metal roof, painting and drywall, landscaping, and a complete home Code evaluation and corrective action. His professional work easily yielded an increase of my home's value at double what I spent on the project. That ROI clearly will show up if/when I sell the house in 2026 or beyond. In a highly confident and in an unqualified manner I strongly recommend Positive Design and Mark to anyone needing all manner of home construction from a true professional and frankly a nice guy. Louis J Garday Sr. More Background information: Sometimes you get lucky. I was introduced to Mark at a dinner in late 2024 and the conversation turned to the details of the multi-faceted work I needed need to renovate and upgrade my 4,000 sf home on ten acres preparatory to selling it in the Spring of 2026 (my best estimate at the time for the optimum timing to sell based on the political/economic chaos brought on by Fed, the then current administration and pending tax law changes during the four years ending in January 2025). I have a lifetime and some 50 years' experience in the construction and real property development businesses, know the trades and have built or developed multiple commercial properties and was impressed with his knowledge during our dinner. The following Monday I received a call from Mark asking if he could walk my property with me and organize my thoughts on what I characterized as extensive work. What followed was a long and detailed survey he compiled of what was needed to remodel and reposition a 30-year-old valuable and custom log home and natural 10-acre landscape of some 200 Ponderosa Pine Trees, surrounded by the San Juan National Forest. Mark made extensive notes and revisited me a few days later, with a detailed proposal, cost estimates, a few new ideas to maximize what I had in place, a time and materials schedule, work timing and scheduling (what us old time real estate guys call a PERT Chart). This being a new relationship and having just met Mark, I agreed to bite off the first phase immediately and Mark began the (bring it up to Code phase) the following Monday in December 2024. Work began immediately and he moved his equipment into my carport and began working. I need not have worried about Mark and the process. He did a great job from Day through the completion.

"Mark remolded our home when we bought it to perfection!!! He built a corner fireplace; a new kitchen with built in cabinet with glass doors and lights for displays. We have the most amazing master bath as he built a round shower stall, walkin with 5 shower heads, a seat and all done in glass bricks. The window is all glass bricks to let the light in with an open small window at the top to let steam out and fresh air in if wanted. A beautiful tile inlaid floor rhat is heated as wanted that he designed. Many people have come to look at it and he built several more!! He comes to fix anything or make something better when ever he is needed. He builds remarkable original things which he designs to fit the space and to last for ever! He is an artist and a very talented guy!!! I would not have anyone else do the kind of work Mark does!! Leslie Hawkinson"

He did a fabulous job & it looked like a new home!! All new kitchen, new wiring, a lot of new plumbing, new bathroom tub surround, new vanity & lighting , all new paint, floors refinished & new door locks & some new doors for closets & exterior doors. I was very pleased with his hard work & the finished project."

"4.5 stars - Mark Posiviata at Positive Design Build LLC did a beautiful job designing and building my laundry/mudroom. The cabinets, bench, and countertop are absolutely stunning, and the craftsmanship is truly top-notch. The quality of work and attention to detail really show — the space is both functional and gorgeous. Design-wise, Mark was excellent to work with. He listened carefully, offered great ideas/suggestions, and delivered a final result that exceeded my expectations. I’m thrilled with how the room turned out and receive compliments on it all the time. The only area for slight improvement would be communication and coordination with contractors during the process, which could have been smoother at times. That said, the end result was well worth it. I would absolutely recommend Mark and Positive Design Build LLC for anyone looking for high-quality custom work and thoughtful design."

Custom Home Building FAQ for Durango CO
Answers to the questions we hear most from homeowners planning custom builds in Durango, the Animas Valley, and across La Plata County.
Frequently Asked Questions
How do I find Durango residential contractor reviews?
Start by checking Google Business Profile reviews and asking any builder you're considering for local references you can actually call. In Durango, it's worth visiting past project sites in person — a portfolio photo doesn't tell you how the finishes hold up after a few La Plata County winters. At Positive Design Build, we encourage prospective clients to speak directly with our past homeowners. We also recommend vetting builders for technical expertise in mountain construction, not just curb appeal — a home that looks great but wasn't engineered for our climate won't serve you well long-term.
What is the cost of a room addition in Durango?
Room additions in Durango vary significantly based on scope and complexity. A master suite addition typically costs more than a kitchen expansion due to plumbing, HVAC extension, and structural tie-in requirements. Mountain homes present specific challenges — tying a new structure into an existing roofline on a sloped lot requires careful engineering, and matching materials on older homes adds cost. That said, well-planned additions in the Durango market consistently increase property value. We provide detailed cost breakdowns during our feasibility phase so you know exactly what to expect before committing.
Do you have sloped lot house plans for Durango properties?
Every sloped lot in Durango is different, so we design custom plans rather than pulling from a catalog. Our engineering team specializes in walk-out basements, tiered foundations, and stepped floor plans that work with the terrain instead of fighting it. Proper slope engineering also addresses drainage management — critical on Durango hillsides where snowmelt and summer storms can cause erosion. Building on a slope does add cost compared to flat ground, but the trade-off is the panoramic Animas Valley views that make Durango properties so desirable. We'll give you an honest cost comparison during your site analysis.
How long does it take to build a custom home in Durango?
Most custom homes in Durango take 10 to 16 months from groundbreaking to move-in, depending on size and complexity. Seasonal weather plays a major role — concrete pours and foundation work are best started in spring or early summer to avoid winter delays. La Plata County permitting typically runs 4 to 8 weeks depending on your lot's requirements. Our design-build model cuts overall timelines by running design and pre-construction in parallel, so you're not waiting months for an architect to finish before your builder can start planning.
What is a Passive House and is it right for Durango?
A Passive House is a building standard focused on extreme energy efficiency — we're talking 80-90% less heating energy than a conventional home. The approach relies on superinsulated walls, airtight construction, heat recovery ventilation, and high-performance windows. For Durango, where winter temperatures regularly drop below zero and heating bills can be punishing, Passive House design makes strong financial sense over the life of the home. The superior air sealing also means better indoor air quality and remarkable quiet. The upfront investment typically pays back through utility savings within 7 to 10 years, and the comfort difference is noticeable from day one.
How do you manage builds for out-of-town clients?
A significant portion of our Durango projects are second homes for clients who live out of state. We use digital project management tools with real-time photo updates, scheduled video walkthroughs, and detailed progress reports so you always know exactly where your build stands. We coordinate virtual design meetings during the planning phase and schedule in-person site visits at key milestones — foundation pour, framing completion, and finish selections. As your local boots-on-the-ground in La Plata County, our team handles everything from subcontractor coordination to county inspections so you don't have to fly in for every decision.
Are you a licensed general contractor in Durango?
Yes, Positive Design Build is a fully licensed general contractor operating in La Plata County and throughout Southwest Colorado. We carry comprehensive general liability insurance and bonding coverage that exceeds local requirements. Our team maintains current knowledge of Durango building codes, La Plata County zoning regulations, and wildfire mitigation requirements that apply to mountain construction. We handle all permitting, inspections, and code compliance as part of our design-build service.
What is the best way to heat a home in Durango?
For Durango's high-altitude climate, we typically recommend a combination approach. Radiant floor heating provides consistent, even warmth throughout the home without the drafts and noise of forced air — especially effective on concrete slab and tile floors common in mountain homes. High-efficiency heat pumps have become viable even at Durango's elevation, handling moderate cold while a backup system covers the coldest stretches. Many of our clients also love a Rumford fireplace — an efficient, tall-opening design that radiates more heat into the room than a standard firebox. We design the heating strategy alongside the building envelope so the whole system works together.
