Mountain & Lake House Construction in Arboles
From A-frame lake houses overlooking Navajo Lake to rugged modern cabins built for Archuleta County winters, we specialize in mountain home construction engineered for the Arboles environment.
Building for the Arboles Environment
Arboles sits at the southern edge of Archuleta County where the San Juan foothills meet Navajo Lake — a landscape that demands mountain home construction built for real conditions, not generic building codes. We've been building in this corridor for over eight years and know what the terrain, weather, and soil throw at a structure.
Properties near Navajo Lake require waterfront-specific foundation systems that account for clay-heavy soils, seasonal moisture fluctuation, and variable bearing capacity. We work with geotechnical engineers to test every building site before design begins, then specify pier-and-grade-beam foundations, helical piles, or reinforced spread footings based on what's actually underfoot — not assumptions. Engineering for high snow loads and thermal bridging in Southwest Colorado is built into every structural plan from the start.
The Arboles landscape also means wildfire preparedness isn't optional. We build with ignition-resistant materials, design defensible space into every site plan, and install high-performance windows and insulation systems that handle the temperature extremes between summer lake days and sub-zero January nights. Your mountain home construction in Arboles needs to perform year-round, and we engineer it that way.

Lake House & Cabin Designs for Arboles
Lake house designs near Arboles start with the view. Whether you're building a year-round family home or a weekend retreat on Navajo Lake, we design floor plans that orient living spaces toward the water and mountains while managing solar exposure, prevailing winds, and site access.
Our modern cabin plans for Arboles combine the warmth of natural materials — wood, stone, and steel — with contemporary open layouts that make compact spaces live large. Specialized deck construction using composite and engineered hardwood materials gives you outdoor living space that handles Archuleta County weather without the maintenance burden of traditional wood decking. Every lakefront deck we build is engineered for snow loads and UV exposure specific to this elevation.
For vacation properties, our A-frame house designs in Colorado are a proven fit. The steep roofline sheds snow efficiently, the interior volume creates dramatic living spaces with minimal square footage, and the iconic silhouette sits naturally in the Arboles landscape. We also offer custom home building in Arboles for clients who want a fully bespoke design from the ground up.

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."

Building a Cabin in Arboles — FAQ
Answers to the questions we hear most from homeowners planning mountain and lake house builds near Navajo Lake and throughout Arboles.
Frequently Asked Questions
What are the challenges of building a cabin in Arboles?
Building a cabin in Arboles presents three main challenges that most builders underestimate. First, remote site access — many Arboles properties sit off unpaved county roads that require careful logistics for heavy equipment and material deliveries, especially during spring mud season. Second, soil stability near Navajo Lake can vary dramatically; waterfront and near-shore lots often have clay-heavy soils that shift with moisture levels and require engineered foundation systems. Third, utility infrastructure is limited in parts of Arboles, meaning wells, septic systems, and off-grid power solutions need to be factored into your build plan from day one. We've navigated all of these on multiple Arboles projects and plan for them during the design phase, not as surprises during construction.
Do you build A-frame homes near Navajo Lake?
Absolutely — A-frame house designs are one of our favorite builds for the Arboles area. The classic A-frame silhouette is more than aesthetics; the steep roofline sheds heavy Archuleta County snow loads efficiently, reducing the structural demands on the roof system compared to conventional pitch designs. We build both traditional A-frames and modern interpretations that open up interior living space with loft bedrooms, vaulted great rooms, and large gable-end windows framing Navajo Lake views. Our A-frame designs in Colorado incorporate updated insulation systems, modern mechanical layouts, and open floor plans that make a small footprint live much larger than the square footage suggests.
How do you handle steep slope construction in Arboles?
Steep slopes around Arboles call for engineered solutions tailored to the specific grade and soil conditions of your lot. We use specialized foundation pier systems drilled into stable bearing strata below the surface, which allows us to build on slopes that would be unbuildable with conventional footings. For steeper grades, engineered retaining walls create level building pads and protect against erosion. Walk-out basement designs are a natural fit on Arboles hillsides — they turn the slope into an advantage by adding a full daylight level with direct outdoor access and views toward Navajo Lake or the surrounding mesas.
What is the snow load requirement for Arboles homes?
Snow load requirements in Arboles follow Archuleta County engineering standards, which are based on elevation, terrain exposure, and roof geometry. Ground snow loads in the Arboles area typically range from 60 to 90 pounds per square foot depending on your specific lot elevation and exposure. Roof pitch plays a significant role — steeper pitches shed snow more effectively and can reduce the design load, while lower pitches require heavier structural framing. Every mountain home we build includes structural engineering calculations specific to your site, with reinforced trusses and connections sized for worst-case snow accumulation, not just average years.
Are your Arboles homes wildfire resistant?
Every home we build in Arboles meets or exceeds Wildland-Urban Interface requirements for Archuleta County. We use ignition-resistant siding materials like fiber cement and fire-rated composite panels, Class A fire-rated roofing, and tempered or dual-pane glazing that resists radiant heat. Eave and soffit venting is designed with ember-resistant screening to prevent fire intrusion at these vulnerable points. Beyond the structure itself, we work with each client on defensible space landscaping — creating fuel breaks, selecting fire-resistant native plantings, and positioning the home to reduce exposure. The dry pinyon-juniper landscape around Navajo Lake makes these measures essential, not optional.
Can you build a modern mountain home on Navajo Lake?
We specialize in modern mountain homes designed for lakefront living near Navajo Lake. Modern cabin plans for the Arboles area feature large glass view walls that frame lake and mesa views while maintaining energy efficiency through high-performance low-E glazing. We blend natural material palettes — native stone, reclaimed timber, weathered steel — with clean contemporary lines that feel connected to the Southwest Colorado landscape. Energy-efficient building envelopes with continuous insulation and passive solar orientation keep these homes comfortable through both summer heat and winter cold without excessive energy costs. The result is a home that looks striking on the lake and performs for decades.
What are the best materials for a lakefront home in Colorado?
Lakefront properties near Navajo Lake face UV exposure, temperature swings, wind-driven moisture, and occasional freeze-thaw cycles that punish standard building materials. For decking, we recommend composite materials like TimberTech or Trex that resist moisture, UV fading, and insect damage without the annual maintenance that wood decking demands at altitude. Stone veneers — both natural and manufactured — provide durable, low-maintenance exteriors that tie the home into the Arboles landscape. Fiber cement siding handles temperature extremes and resists fire, rot, and insect damage far better than wood alternatives. We select every exterior material for 30-plus year performance in lakefront conditions.
Do you offer pre-designed cabin plans?
We offer a collection of customizable cabin and mountain home starting plans that have been proven on Arboles and Southwest Colorado building sites. These aren't generic catalog plans — they're designs we've refined through actual builds in this terrain and climate, with foundation systems, roof structures, and insulation details already engineered for Archuleta County conditions. Small footprint cabins from 800 to 1,400 square feet are popular for vacation properties near Navajo Lake, and our pre-designed options allow fast-track construction timelines since engineering and permitting documentation is already developed. Every plan can be customized to your lot orientation, view preferences, and lifestyle needs.
