Home Addition Contractors in Durango: Major Structural Renovations
From master suite additions to complete gut renovations — Positive Design Build transforms Durango homes with structural expertise built for mountain living. Over years of major renovation experience in La Plata County.
Strategic Home Additions & Structural Changes
When your Durango home needs more space, the solution isn't always building out. Sometimes it's building up, restructuring what's there, or adding exactly the right rooms in exactly the right places. As experienced home addition contractors in Durango, we engineer every expansion to blend seamlessly with your existing home and the mountain terrain around it.
Seamless Architectural Integration
Durango's homes span everything from historic Victorian-era houses in the downtown corridor to modern mountain builds in the Three Springs neighborhood. We match rooflines, siding materials, window proportions, and foundation levels so your addition looks like it was always part of the original design — not an afterthought bolted onto the side. Every room addition cost in Durango reflects the care we put into this integration work.
Second-Story Expansions
Adding a second story to a house in Durango is one of the smartest ways to gain square footage without expanding your footprint — critical on smaller lots in neighborhoods like Animas City and Crestview. We handle the structural engineering required to reinforce existing foundations for vertical loads, and we design upper levels that capture the San Juan mountain views that make Durango living special. It's specialized work that demands experienced home addition contractors.
Master Suite Additions
A master suite addition in Durango transforms your home into the retreat it should be. We build luxury primary suites with spa-quality bathrooms — heated tile floors, soaking tubs positioned for mountain views, walk-in showers with frameless glass — and private balconies that take advantage of Durango's 300 days of sunshine. Every master suite we build is designed around how you actually live, not a generic floor plan from a catalog.

Whole-Home Remodeling & Gut Renovations
Some Durango homes need more than a surface refresh — they need to be taken down to the studs and rebuilt from the inside out. Our gut renovation process modernizes older homes while preserving the character and location that made you fall in love with the property in the first place.
Full Gut Renovations
When we gut a Durango home, we strip it to the structural bones and rebuild every system — new electrical panels and wiring, modern plumbing, high-efficiency HVAC, and upgraded insulation throughout. Many older homes along Durango's main corridors and in the historic neighborhoods were built before current energy codes existed. A full gut renovation lets us bring these homes into the modern era while keeping the exterior character that gives Durango its identity. We handle everything from demolition through final finishes.
Energy & Code Modernization
Older Durango homes often have single-pane windows, minimal insulation, and outdated electrical systems that can't support modern living. We modernize these homes to meet current IRC building standards and energy efficiency requirements — proper vapor barriers for mountain humidity swings, spray foam insulation in roof cavities, and mechanical ventilation that manages indoor air quality at altitude. The result is a home that costs significantly less to heat through Durango's winters.
Open-Concept Conversions
Converting a compartmentalized floor plan to open concept requires removing load-bearing walls and installing engineered steel or laminated veneer lumber beams to carry the structural loads above. This isn't a weekend DIY project — it's precision structural work that demands experienced contractors who understand how forces transfer through a mountain home's framing system. We design beam installations that open up sight lines to your views and create the flowing living spaces that today's Durango homeowners want, while maintaining full structural integrity.
Living Through a Renovation
We know that many Durango families choose to stay in their homes during major renovations. Our phased construction approach isolates work zones with HEPA filtration and physical barriers, maintains access to essential rooms, and keeps daily disruption to a minimum. We schedule the noisiest and dustiest work during predictable windows and communicate the plan clearly so your family knows what to expect each week. Clean job sites and respectful crews are non-negotiable on every project.

"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.

Home Addition & Renovation FAQs for Durango
Common questions about room additions, whole-home remodels, and major renovations in Durango, CO.
What is the typical 20x20 room addition cost in Durango?
A 20x20 room addition in Durango typically costs between $150,000 and $250,000, depending on foundation requirements, finish levels, and the specific challenges of your property. Southwest Colorado's mountain terrain means many sites need engineered foundations that account for rocky soil conditions, steep grades, and frost depths that can reach 36 inches or more. Snow-load requirements in Durango also influence structural framing costs — roof systems need to handle significant weight. We provide detailed, itemized estimates after a site visit so you know exactly what drives the cost on your specific property.
How much does a sunroom addition cost in Durango?
Four-season sunroom additions in Durango range from $75,000 to $150,000 depending on size, glazing specifications, and foundation type. At our altitude, high-performance glazing is essential — we use low-E, argon-filled units that block intense UV radiation while preventing heat loss during Durango's cold months. A well-designed sunroom should be comfortable year-round without running a dedicated heating system at full blast. We engineer every sunroom addition for Durango's snow loads and solar exposure, so you get a room that performs as well as it looks against the San Juan backdrop.
Do I need a permit for a home addition in Durango?
Yes, all structural changes in Durango require permits — either through the City of Durango or La Plata County, depending on your property's jurisdiction. The permitting process includes plan review, structural engineering approval, and a series of inspections from foundation through final occupancy. Positive Design Build handles the entire permitting and site planning process for every addition project. We submit plans, coordinate with inspectors, and manage the timeline so you don't have to navigate the bureaucracy yourself. Our established relationships with local building departments help keep approvals moving efficiently.
How long does a major home renovation take?
Major gut remodels in Durango typically take 6 to 12 months from demolition to completion, depending on the scope of structural, mechanical, and finish work involved. Room additions generally run 4 to 8 months. Weather plays a role — exterior work and foundation pours are best scheduled during Durango's building season from May through October. We create detailed project schedules before breaking ground and update them weekly, so you always know where things stand. Our experience managing renovation timelines in mountain conditions means fewer surprises and tighter delivery.
Can I add a second story to my house in Durango?
Yes, adding a second story to a house in Durango is absolutely possible, provided the existing foundation can be reinforced to meet current structural codes and snow-load requirements. It's an excellent way to capture mountain and valley views in established Durango neighborhoods like Animas City, Crestview, and Hillcrest — where lot sizes don't allow horizontal expansion. We start every second-story project with a thorough structural assessment of the existing foundation and framing. The engineering for vertical expansion in Durango's snow country is specialized work, and it's one of our strengths as home addition contractors in Durango.
What is the cost of a master suite addition?
A master suite addition in Durango typically starts around $175,000 for a luxury suite with a custom bathroom, walk-in closet, and quality finishes. Final pricing depends on plumbing complexity — especially if you're adding the suite on the opposite side of the house from existing water lines — and the level of finish materials you select. Many of our Durango clients opt for heated tile floors, soaking tubs with mountain views, and custom cabinetry that pushes the total higher. We walk you through material and design options at every price point so the suite fits both your lifestyle and your budget.
Is a whole home remodel cheaper than building new?
A whole-home remodel can save 20 to 30 percent compared to new construction if the existing structure's core — foundation, framing, and roof — is sound. In Durango, remodeling is often the only practical option in established neighborhoods like Animas City or the historic downtown area where vacant lots simply don't exist. You also avoid the time and cost of new utility connections, driveway construction, and landscaping from scratch. We conduct a thorough structural assessment before recommending a gut remodel to make sure the savings are real and the existing bones can support the renovation you want.
How do you handle dust and debris during a renovation?
We take dust and debris management seriously on every Durango renovation project, especially when homeowners are living in the house during construction. Our standard practice includes HEPA-filtered air scrubbers running continuously in work zones, heavy-duty plastic barriers with zippered access doors to seal off living areas, and dedicated pathways for crew traffic that keep construction activity away from your daily routine. We perform daily site cleanup at the end of every work day and use professional waste management services for debris removal. Your home stays as clean and livable as possible throughout the renovation process.
