Comprehensive Construction & Addition Capabilities
✔ Site Preparation, Excavation & Foundations
Every successful addition begins with proper site preparation, and our team handles all excavation, grading, and foundation work with precision. We evaluate soil conditions, drainage requirements, and elevation concerns—especially important in Summit County’s sloped or hillside properties. Our foundations are engineered to support snow loads, long-term structural stability, and seamless integration with your existing home. This careful groundwork ensures your addition is built on a strong, durable base that will perform well for decades.
✔ Framing, Roofing & Exterior Integration
We frame new additions to align perfectly with your home’s architecture, structural layout, and rooflines. Our carpentry team builds durable, code-compliant framing designed to handle Summit County’s heavy snow loads and seasonal temperature changes. We then integrate roofing, siding, stonework, stucco, windows, and exterior trim to match your home’s existing appearance. The result is an addition that looks original—not like something tacked on later—while maintaining high structural integrity and curb appeal.
✔ Windows, Insulation & Energy Efficiency
High-elevation homes in Park City and Summit County require efficient insulation systems to stay warm during long winters. We install premium windows, high-R-value insulation, vapor barriers, and air-sealing measures that keep your addition comfortable year-round. This improves energy efficiency, helps reduce heating costs, and ensures that new spaces feel just as warm and quiet as the rest of your home. Our insulation and window packages meet or exceed Summit County’s strict energy codes.
✔ Plumbing, Electrical & HVAC Extensions
We extend and upgrade all necessary utilities to support your new addition, including plumbing lines, electrical circuits, and HVAC routing. Our team ensures your home’s mechanical systems can handle the added square footage, making adjustments for airflow, heating demand, and electrical loads. Whether you’re adding a new bathroom, expanding a kitchen, or building a heated garage, we integrate modern, safe, and efficient systems that meet local codes and deliver long-term reliability.
✔ Interior Finish Work & Custom Details
Interior finishes are what transform an addition from a construction project into a seamless, lived-in space. We install premium flooring, trim, doors, lighting, cabinetry, drywall, paint, windowsills, built-ins, and more—matched to your home’s existing style or upgraded for a more modern look. Whether your home features rustic mountain accents, modern minimalist finishes, or traditional architectural details, we tailor each interior element to ensure a polished, cohesive final result.
✔ Structural Engineering, Design Coordination & Architectural Blending
Larger or more complex additions often require structural engineering to ensure safety and long-term performance. We coordinate with engineers and architectural designers to plan roof tie-ins, beam placements, load-bearing wall modifications, and site-specific structural needs. This is especially important in Summit County, where snow load, wind exposure, and hillside construction demand precise engineering. Our integrated process ensures your new addition looks beautiful, meets building standards, and performs reliably in all seasons.
Garage Additions & Detached Garages in Summit County
Garage additions are one of the most valuable upgrades for Summit County homeowners, providing essential storage, protected parking, and practical space for year-round mountain living. Whether you’re in Park City, Jeremy Ranch, or the Snyderville Basin, we build garage additions that blend seamlessly with your home and stand up to high-elevation weather conditions.
✔ Attached Garage Additions
Attached garage additions provide valuable protected parking, improved convenience, and extra storage for skis, mountain bikes, or outdoor gear. We build single-, double-, and multi-bay garages with insulation, modern doors, and architectural matching to your home.
✔ Detached Garages & Workshops
Detached garages offer flexibility for storage, hobbies, or equipment common in mountain living. We build RV garages, multi-bay structures, heated workshops, and equipment storage buildings, all engineered for Summit County snow loads and winter weather conditions.
✔ Garage-to-Living-Space Conversions
For homeowners who need more interior space, we convert existing garages into guest suites, offices, gyms, hobby rooms, or additional living areas. These conversions are fully insulated, heated, and finished to blend with the rest of the home.
